Switch Explosion-Protection Specifications (Japan only)
Simple apparatuses in accordance with relevant standards of each country can be installed in the hazardous area and connected to the EB3C located in the safe area.
In Japan, any switches, though regarded as simple apparatuses, must be certified for explosion-proof devices. EB9Z-A and EB9Z-A1 are IDEC’s generic Part No. of
any single apparatuses certified by TIIS for use with the EB3C, therefore simple apparatuses with specifications shown below can be used as those approved by the
Japanese explosion-proof certification.

Notes
• As shown in the diagram on the left, a required number of “contacts in one
switch” (3 contacts in the example at left) can be added to the “contacts in
one switch” connected to one input channel.
• Similarly, a required number of “contacts in one switch” can be added to a
common line connected to multiple input channels.
• The capacitance and inductance of the added “contacts in one switch”
must be included in the calculation of the wiring capacitance and inductance in “Precautions for Operation, 5. Wiring for Intrinsic Safety, (7)” on
page 11.
• In addition, a required number of contacts can be added in the enclosure of
“contacts in one switch.” In this case, however, do not include the capacitance and inductance in the calculation of the wiring capacitance and
inductance on page 11. Instead, make sure that the internal capacitance
(Ci) and internal inductance (Li) are within the values shown in the table
“Switch Explosion-Protection Specifications (Japan only)” on page 6.

EB3C Relay Barrriers
Operating Instructions
1. Installation of EB3C Relay Barriers
Applicable Switches
(1) The EB3C can be installed in any direction.
(2) Install the EB3C relay barrier in a safe area (non-hazardous area) in
accordance with intrinsic safety ratings and parameters. To avoid
mechanical shocks, install the EB3C in an enclosure which suppresses
shocks.
Control
Switches
(3) When installing or wiring the EB3C, prevent electromagnetic and
electrostatic inductions in the intrinsically safe circuit. Also prevent the
intrinsically safe circuits from contacting with another intrinsically safe
circuit and any other circuits.
Maintain at least 50 mm clearance, or provide a metallic separating
board between the intrinsically safe circuit and non-intrinsically safety
circuit. When providing a metallic separating board, make sure that
the board fits closely to the enclosure (top, bottom, and both sides).
Allowable clearance between the enclosure and board is 1.5 mm at the
maximum.
Sensing
Switches
The clearance of 50 mm between the intrinsically safe circuit and
non-intrinsically safe circuit may not be sufficient when a motor circuit
or high-voltage circuit is installed nearby. In this case, provide a wider
clearance between the circuits referring to 5 (3) “Minimum Parallel
Distance between the Intrinsically Safe Circuit and Other Circuits.”
(4) In order to prevent contact between intrinsically safe circuits and nonintrinsically safe circuits, mount EB3C units with terminals arranged in
the same direction.

Note: For installation in hazardous areas and connection to the EB3C, use switches which
are certified, approved, or considered to be simple apparatus in relevant standards in
each country.
(2) When the switch has internal wiring or lead wire, make sure that the
values of internal inductance (Li) and capacitance (Ci) are within the
certified values.
(3) Enclose the switch contact’s bare live part in an enclosure of IP20 or
higher protection.
(4) Depending on the explosion-protection specifications according to TIIS,
the exposed area of plastic switch operator is limited as follows:
• Exia II CT6 (EB9Z-A):
20 cm2 maximum
• Exia II BT6 (EB9Z-A1):
100 cm2 maximum
(5) Attach the certification mark supplied with the EB3C on the EB9Z-A or
EB9Z-A1 switch (for Japan application).
(6) When the switch operator of plastic enclosure has a wider exposed
area than the following limits, attach a caution label as shown below.

(5) Maintain at least 6 mm (or 3 mm according to IEC60079-11: 1999)
clearance between the terminal of intrinsically safe circuit and the
grounded metal part of a metal enclosure, and between the relay
terminal block of an intrinsically safe circuit and the grounded metal
part of a metal enclosure.
(6) For installing the EB3C, mount on a 35-mm-wide DIN rail or directly
on a panel using screws. Make sure to install securely to withstand
vibration. When mounting on a DIN rail, push in the clamp completely.
Use the BNL6 end clips on both sides of the EB3C to prevent from
moving sideways.
Caution Label Example
(7) For the 1-circuit separate wiring, a resistor to prevent reed switch
contact welding and an LED miniature pilot lights can be connected in
series with the contact. See below. Use the terminal screw of M3 or
larger.

(7) Excessive extraneous noise may cause malfunction and damage to
the EB3C. When extraneous noise activates the voltage limiting circuit
(thyristor), remove the noise source and restore the power.

2. Terminal Wiring
(1) Using a ø5.5 mm or smaller screw driver, tighten the terminal screws
(including unused terminal screws) to a torque of 0.6 to 1.0 N·m
(recommended value).
(2) Make sure that IP20 is achieved when wiring. Use insulation tubes on
bare crimping terminals.
(3) To prevent disengaged wires from contacting with other intrinsically
safe circuits, bind together the wires of one intrinsically safe circuit.
(4) When the adjacent terminal is connected to another intrinsically safe
circuit, provide an insulation distance of at least 6 mm.

EB3C Relay Barrriers
Operating Instructions
4. Output Specifications
(1) When wiring the output from the EB3C, connect the non-intrinsically
safe circuit to terminals A and C. The EB3C output circuit is not
equipped with short-circuit protection. If required, provide a protection
in the external circuit.
(2) Relay Output
Some types of loads generate reverse emf (such as solenoids) or cause
a large inrush current (incandescent lamps), resulting in a shorter
operation life of output relay contacts. The operation life of contacts
can be extended by preventing the reverse emf using a diode, RC, or
varistor, or by suppressing the inrush current using a resistor or RL.

(4) When identifying intrinsically safe circuits by color, use light blue
terminal blocks and cables.
Contacts are made of gold-clad silver. When using at a small current
and a low voltage (reference value: 0.1 mA, 0.1V), test the contact on
the actual circuit in advance.
(5) When using two or more EB3C’s to set up one intrinsically safe circuit
in the common wiring configuration, interconnect two neutral terminals
(N1 through N10) on each EB3C between adjacent EB3C’s in parallel.
(3) Transistor Output
When connecting a small load, the load may not turn off because of a
leakage current, even though the transistor output is turned off. If this
is the case, connect a resistor in parallel with the load to bypass the
leakage current.
When an excessively high voltage (clamps at 33V, 1W) or a reverse
voltage is applied to the output terminals, the clamping circuit or output
transistor may be damaged.
(6) Make sure that the power of the EB3C and contact are turned off before
starting inspection or replacement.
(7) When wiring the intrinsically safe circuit, determine the distance to
satisfy the wiring parameters shown below. Note that parameters are
different between separate wiring and common wiring.
When driving an inductive load, be sure to connect a diode across the
load to absorb reverse emf.

Example of Overvoltage Absorption Circuit
(4) In the common wiring only models, the output terminals are not isolated
from each other.
(5) When connecting the connector model EB3C’s in parallel, use one
power supply to power the EB3C’s. Do not connect any wiring to the C1
and C2 terminals.
5. Wiring for Intrinsic Safety
(1) The voltage applied on the general circuit connected to the nonintrinsically safe circuit terminals of the EB3C relay barrier must be
250V AC, 50/60Hz, or 250V DC at the maximum under any conditions,
including the voltage of the input power and the internal circuit.
(2) When wiring, take into consideration the prevention of electromagnetic
and electrostatic charges on intrinsically safe circuits. Also, prevent
intrinsically safe circuits from contacting with other circuits.
(3) The intrinsically safe circuits must be separated from non-intrinsically
safe circuits. Contain intrinsically safe circuits in a metallic tube or duct,
or separate the intrinsically safe circuits referring to the table below.
Note: Cables with a magnetic shield, such as a metallic sheath, prevent
electromagnetic induction and electrostatic induction, however, a nonmagnetic shield prevents electrostatic induction only. For non-magnetic
shields, take a preventive measure against electromagnetic induction.
Finely twisted pair cables prevent electromagnetic induction. Adding
shields to the twisted pair cables provides protection against electrostatic
induction.

∗ The 4.8 or 3.2 recess is needed only when using an anti-rotation
ring or a nameplate with an anti-rotation projection.
EB3P-LHW does not have an anti-rotation groove.
Lamp Test
When checking the lamp lighting without using the EB3L lamp barrier,
first make sure that the atmosphere is free from explosive gases.
Connect a 12V DC power supply and a protection resistor of 1 kΩ in
series to turn on the pilot light.

Note: The wiring in dashed line does not affect the operation of the EB3L.
Applicable connector is IDEC’s JE1S-201.
Output power for PLC outputs is supplied by the EB3L, therefore the PLC output does not
need an external power supply.

EB3L Lamp Barrriers
Operating Instructions
1. Installation of EB3L Lamp Barriers
2. Terminal Wiring
(1) The EB3L can be installed in any direction.
(2) Install the EB3L lamp barrier in a safe area (non-hazardous area)
in accordance with intrinsic safety ratings and parameters. To
avoid mechanical shocks, install the EB3L in an enclosure which
suppresses shocks.
(3) When installing or wiring the EB3L, prevent electromagnetic
and electrostatic inductions in the intrinsically safe circuit. Also
prevent the intrinsically safe circuits from contacting with another
intrinsically safe circuit and any other circuits.
Maintain at least 50 mm clearance, or provide a metallic separating
board between the intrinsically safe circuit and non-intrinsically
safety circuit. When providing a metallic separating board, make
sure that the board fits closely to the enclosure (top, bottom, and
both sides). Allowable clearance between the enclosure and board
is 1.5 mm at the maximum.
The clearance of 50 mm between the intrinsically safe circuit and
non-intrinsically safe circuit may not be sufficient when a motor
circuit or high-voltage circuit is installed nearby. In this case,
provide a wider clearance between the circuits referring to 6. (3)
“Minimum Parallel Distance between the Intrinsically Safe Circuit
and Other Circuits.”
(4) In order to prevent contact between intrinsically safe circuits and
non-intrinsically safe circuits, mount EB3L units with terminals
arranged in the same direction.
(1) Using a ø5.5 mm or smaller screw driver, tighten the terminal
screws (including unused terminal screws) to a torque of 0.6 to 1.0
N·m (recommended value).
(2) Make sure that IP20 is achieved when wiring. Use insulation tubes
on bare crimping terminals.
(3) To prevent disengaged wires from contacting with other intrinsically
safe circuits, bind together the wires of one intrinsically safe circuit.
(4) When the adjacent terminal is connected to another intrinsically
safe circuit, provide an insulation distance of at least 6 mm.

(5) Maintain at least 6 mm (or 3 mm according to IEC60079-11: 1999)
clearance between the terminal of intrinsically safe circuit and the
grounded metal part of a metal enclosure, and between the relay
terminal block of an intrinsically safe circuit and the grounded
metal part of a metal enclosure.
(6) For installing the EB3L, mount on a 35-mm-wide DIN rail or directly
on a panel using screws. The EB3L can be installed in any direction.
Make sure to install securely to withstand vibration. When mounting
on a DIN rail, push in the clamp completely. Use the BNL6 end clips
on both sides of the EB3L to prevent from moving sideways.
(7) Excessive extraneous noise may cause malfunction and damage
to the EB3L. When extraneous noise activates the voltage limiting
circuit (thyristor), remove the noise source and restore the power.
22
3. Signal Input
(1) Connect the EB3L to the switches or output equipment which have
a low leakage current (0.1 mA maximum).
(2) The EB3L is equipped with power supply. Do not apply external
power to the EB3L.
(3) When connecting the EB3L’s of connector model in parallel, make
sure that the same power supply is used. When using C1 and C2
terminals to supply power to outside equipment, maintain the
current at 50 mA maximum.
4. Power Voltage
(1) Do not apply an excessive power voltage, otherwise the EB3L may
be damaged.
(2) The EB3L of AC power type may operate at a low voltage (approx.
20V).
5. Pilot Lights, Illuminated Switches, and Buzzers in the
Hazardous Area
(1) EB3P and IPL1 units shown on page 14 can be used with the EB3L.
Buzzers cannot be connected in common wiring.
(2) Install the EB3P and IPL1 units on enclosures of IP20 or higher
protection. Use a metallic enclosure with magnesium content of
7.5% or less (steel and aluminum are acceptable).
(3) When wiring, make sure of correct polarities of the EB3P and IPL1.
(4) Certification mark is supplied with the units. Attach it on the visible
area of the EB3P or IPL1 (for Japan application).
(5) When connecting illuminated switches to the EB3L lamp barrier
and the EB3C relay barrier, a maximum of 16 channels can be
connected in common wiring.
EB3L Lamp Barrriers
Operating Instructions
6. Wiring for Intrinsic Safety
(1) The voltage applied on the general circuit connected to the nonintrinsically safe circuit terminals of the EB3L lamp barrier must
be 250V AC, 50/60Hz, or 250V DC at the maximum under any
conditions, including the voltage of the power line and the internal
circuit.
(2) When wiring, take into consideration the prevention of
electromagnetic and electrostatic charges on intrinsically safe
circuits. Also, prevent intrinsically safe circuits from contacting with
other circuits.
(3) The intrinsically safe circuits must be separated from nonintrinsically safe circuits. Contain intrinsically safe circuits in a
metallic tube or duct, or separate the intrinsically safe circuits
referring to the table at right.
Note: Cables with a magnetic shield, such as a metallic sheath,
prevent electromagnetic induction and electrostatic induction,
however, a non-magnetic shield prevents electrostatic induction
only. For non-magnetic shields, take a preventive measure
against electromagnetic induction.
Finely twisted pair cables prevent electromagnetic induction.
Adding shields to the twisted pair cables provides protection
against electrostatic induction.

(7) When wiring the intrinsically safe circuit, determine the distance to
satisfy the wiring parameters shown below. Note that parameters
are different between separate wiring and common wiring and
depend on the connected units, such as pilot lights, illuminated
pushbuttons, and buzzers.
a) Wiring capacitance Cw ≤ Co – Ci
Co: Maximum external capacitance of the EB3L
Ci: Internal capacitance of the connected unit
b) Wiring inductance Lw ≤ Lo – Li
Lo: Maximum external inductance of the EB3L
Li: Internal inductance of the connected unit
c) Wiring resistance ≤ Rw
Rw: Allowable wiring resistance
d) Allowable wiring distance D (km) is the smallest value of those
calculated from the capacitance, inductance, and resistance.
D ≤ Cw/C C (nF/km): Capacitance of cable per km
D ≤ Lw/L L (mH/km):
Inductance of cable per km
D ≤ Rw/2R R (Ω/km): Resistance of cable per km
Note: For the details of wiring the intrinsically safe circuits, refer to a
relevant test guideline for explosion-proof electric equipment in
each country.
(4) When identifying intrinsically safe circuits by color, use light blue
terminal blocks and cables.
(5) When using two or more EB3L’s to set up one intrinsically safe
circuit in the common wiring configuration, interconnect two
neutral terminals (N1 through N10) on each EB3L between adjacent
EB3L’s in parallel.
(6) Make sure that the power of the EB3L, pilot lights, and other
connected units are turned off before starting inspection or
replacement.
Safety Precautions
• Do not use the EB3C Relay Barrier and EB3L Lamp Barrier for other than explosion protection purposes.
• Read the user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and inspection of the EB3C
Relay Barrier and EB3L Lamp Barrier.

Operating Instructions
Notes for Operation
1. Do not disassemble, repair, or modify the EB3N safety relay barrier,
otherwise the safety characteristics may be impaired.
2. Use the EB3N within its specification values.
3. The EB3N can be mounted in any direction.
4. Mount the EB3N on a 35-mm-wide DIN rail or directly on a panel surface
using screws. When mounting on a DIN rail, push in the clamp and use end
clips to secure the EB3N. When mounting on a panel surface, tighten the
screws firmly.
5. Excessive noise may cause malfunction or damage to the EB3N. When the
internal voltage limiting circuit (thyristor) has shut down the power due to
noise, remove the cause of the noise before powering up again.
6. The internal power circuit contains an electronic fuse to suppress
overcurrents. When the electronic fuse has tripped, shut down the power,
remove the cause of the overcurrent before powering up again.
7. Use crimping terminals with insulation sheath for wiring. Tighten the terminal
screws, including unused terminal screws, to a recommended tightening
torque of 0.6 to N·m using a screwdriver of ø5.5 mm in diameter.
8. Before inspecting or replacing the EB3N, turn off the power.
Notes for Machine Safety
1. Operate the safety input device to check the EB3N functionality everyday.
2. For safety input devices, such as safety switches or emergency stop
switches, connected to the EB3N, use safety standard-compliant devices
with direct opening action and 2NC contacts.
3. Do not use the auxiliary input as a safety input.
4. For safety control devices connected with the EB3N, use machine safety
standard-compliant devices with a disparity detection function.
5. Use safety inputs and safety outputs in a circuit configuration compliant
with safety requirements.
6. To calculate the safety distance, take into consideration the response time
of all devices comprising the system, such as the EB3N and safety devices
connected to the EB3N.
7. Separate the input and output wiring from power lines and motor lines.
8. When using multiple EB3N safety relay barriers, do not connect one switch
to more than one EB3N. Use separate switches for each EB3N.
9. To ensure EMC, use shielded cables for safety inputs and auxiliary inputs.
Connect the shield to the FG of the control panel on which the EB3N is
mounted.
10. For protection against overcurrents, connect an IEC60127-2-compliant 2A
fast-blow fuse (5 × 20 mm).
11. Evaluate the ISO 13849-1 category and performance level in consideration
of the entire system.
Notes for Explosion Protection Safety
1. Install the EB3N in an enclosure capable of protecting against mechanical
shocks at a hazardous location in accordance with intrinsic safety ratings
and parameters.
2. Install and wire the EB3N so that the EB3N is not subject to electromagnetic
and electrostatic induction and does not contact with other circuits.
For example, keep a minimum spacing of 50 mm between intrinsically safe
and non-intrinsically safe circuits, or provide a metallic separating board
between the intrinsically safe circuit and non-intrinsically safe circuit. When
providing a metallic separating board, make sure that the board fits closely
to the enclosure (top, bottom, and both sides). Allowable clearance between
the board and the enclosure is 1.5 mm at the maximum.
When a motor circuit or high-voltage circuit is installed nearby, keep a wider
spacing than 50 mm between intrinsically safe and non-intrinsically safe
circuits.
3. Keep a minimum spacing of 3 mm between the terminal or relay terminal
block of the intrinsically safe circuit and the grounded metal parts of the
metal enclosure.
4. Connect the terminals so that IP20 is ensured.
5. To prevent disengaged wires from contacting with other intrinsically safe
circuits, bind together the end of wires.
6. Make sure that the voltage of the power supply for the devices connected
to the non-intrinsically safe circuit or the internal voltage of such devices
does not exceed 250V AC/DC 50/60 Hz or 250V DC under any normal and
abnormal conditions.
7. Make sure that the wiring of intrinsically safe circuits does not contact
with other circuits or is not subject to electromagnetic and electrostatic
inductions, otherwise explosion protection is not ensured.
8. When identifying intrinsically safe circuits by color, use light blue terminal
blocks and cables.
9. When wiring the intrinsically safe circuit, determine the distance to satisfy
the wiring parameters shown below.
a) Wiring capacitance Cw ≤ Co – Ci
Co: Intrinsically safe circuit allowable capacitance
Ci: Internal capacitance of switches
b) Wiring inductance Lw ≤ Lo – Li
Lo: Intrinsically safe circuit allowable inductance
Li: Internal inductance of switches
c) Wiring resistance ≤ Rw
Rw: Allowable wiring resistance
Switches in the Hazardous Area
1. A switch contains the switch contact, enclosure, and internal wiring. A
switch contact refers to an ordinary switching device which consists of
contacts only.
2. When the switch has internal wiring or lead wire, make sure that the values
of internal capacitance (Ci) and inductance (Li) are within the certified
values.
3. Enclose the bare live part of the switch contact in an enclosure of IP20 or
higher protection.
4. Depending on the explosion-protection specifications of TIIS, the exposed
area of plastic switch operator, when installed in Japan, is limited as
follows:
