Wiring for Intrinsic Safety, (7)” on page T-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 T-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 T-6.

Installation of EB3C Relay Barriers (1) The EB3C can be installed in any direction. 3. Switches in the Hazardous Area (For Japan application only) (2) Install the EB3C relay barrier in a safe area (non-hazardous area) in accordance with intrinsic safety ratings and param­ eters. To avoid mechanical shocks, install the EB3C in an enclosure which suppresses shocks. (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, such as a pushbut­ton switch. See below. (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. The clearance of 50 mm between the intrinsically safe cir­ cuit 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 non-intrinsically safe circuits, mount EB3C units with terminals arranged in the same direction. Intrinsically Safe Circuit EB3C EB3C EB3C Control Switches Sensing Switches Push-pull Switches Pushbutton, Foot, Trigger, Rocker, Grip Twisting Switches Rotary, Selector, Cam, Drum, Thumb wheel Lever and Slide Switches Toggle, Multidirectional, Wobble stick, Lever, Slide switch Displacement Switches Microswitch, Limit, Magnetic proximity, Door, Reed, Mercury Level Switches Liquid level Others Pressure, Temperature 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 opera­ tor 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. Caution EB3C Non-intrinsically Safe Circuit Applicable Switches EB3C Intrinsically Safe Circuit (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. (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. To prevent electrostatic charges, do not rub the switch surface during operation. Use a soft cloth dipped with water for cleaning. II C: 20 cm2 maximum II B: 100 cm2 maximum 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. Applicable Resistor Ratings Resistance 100Ω maximum Rated Wattage 0.5 to 3W Type Metal (oxide) film resistors R 2. Terminal Wiring Reed Switch (1) Using a ø5.5 mm or smaller screw driver, tighten the termi­ nal screws (including unused terminal screws) to a torque of 0.6 to 1.0 N·m (recommended value). Terminal Block (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 intrinsi­ cally safe circuit, provide an insulation distance of at least 6 mm.

Output Specifications (1) When wiring the output from the EB3C, connect the nonintrinsically 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 sole­ noids) 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. 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. (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. When driving an inductive load, be sure to connect a diode across the load to absorb reverse emf. Load An ∗ Cn ∗: Surge Absorber Example of Overvoltage Absorption Circuit (4) In the common wiring only types, the output terminals are not isolated from each other. (5) When connecting the connector type 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 non-intrinsically safe circuit terminals of the EB3C relay bar­rier must be 250V AC, 50/60Hz, or 250V DC at the maxi­ mum 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 nonintrinsically 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 non-magnetic shield prevents electrostatic induction only. For non-magnetic shields, take a preventive measure against electro­magnetic induction.

Display Lights (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. Operator Interfaces (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 dis­ tance to satisfy the wiring parameters shown below. Note that parameters are different between separate wiring and common wiring. a) Wiring capacitance Cw ≤ Co – (Ci + N × 2 nF) Co: Maximum external capacitance of the EB3C Ci: Internal capacitance of the switch N: The number of switches connected in series or parallel (the number is infinite) PLCs Softwares Relays Sockets b) Wiring inductance Lw ≤ Lo – (Li + N × 5 µH) Lo: Maximum external inductance of the EB3C Li: Internal inductance of the switch N: The number of switches connected in series or parallel (the number is infinite) Timers 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.
