*1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.
*2. Wave is standard shock voltage of ±1.2×50 μs according to JEC-212-1981
*3. For ambient temperature, please read “GUIDELINES FOR RELAY USAGE”.
*4. The operate and release voltages rise approximately 0.4% for every 1°C given a standard ambient temperature of 20°C.
Therefore, when using relays where the ambient temperature is high, please take into consideration the rise in operate voltage and keep the coil applied voltage within the
maximum allowable applied voltage.

HANDLING
Mounting method of relay
Removing method of relay
1) Match the direction of relay and socket.
1) Remove the relay, applying force in the direction as shown in
the figure.
2) In case there is not enough
space to grasp relay with
fingers, use screwdrivers
in the way as shown in the
figure.
2) Both ends of the relay are to be secured
firmly so that the socket both hooks on
the top surface of the relay.
3) Exercise care when removing relays. If greater than necessary
force is applied at the socket hooks, deformation may alter the
dimensions so that the hook will no longer catch, and other
damage may also occur.
Please refer to "the latest product specifications"
when designing your product.

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE
For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
Precautions for Coil Input
Long term current carrying
A circuit that will be carrying a current continuously for long periods
without relay switching operation. (circuits for emergency lamps,
alarm devices and error inspection that, for example, revert only
during malfunction and output warnings with form B contacts)
Continuous, long-term current to the coil will facilitate deterioration
of coil insulation and characteristics due to heating of the coil itself.
For circuits such as these, please use a magnetic-hold type latching
relay. If you need to use a single stable relay, use a sealed type
relay that is not easily affected by ambient conditions and make a
failsafe circuit design that considers the possibility of contact failure
or disconnection.
DC Coil operating power
Steady state DC current should be applied to the coil. The wave
form should be rectangular. If it includes ripple, the ripple factor
should be less than 5%.
However, please check with the actual circuit since the electrical
characteristics may vary. The rated coil voltage should be applied to
the coil and the set/reset pulse time of latching type relay differs for
each relays, please refer to the relay's individual specifications.
Maximum allowable voltage and temperature rise
Proper usage requires that the rated coil voltage be impressed on
the coil. Note, however, that if a voltage greater than or equal to the
maximum continuous voltage is impressed on the coil, the coil may
burn or its layers short due to the temperature rise. Furthermore, do
not exceed the usable ambient temperature range listed in the
catalog.
Operate voltage change due to coil temperature rise
In DC relays, after continuous passage of current in the coil, if the
current is turned OFF, then immediately turned ON again, due to the
temperature rise in the coil, the pick-up voltage will become
somewhat higher. Also, it will be the same as using it in a higher
temperature atmosphere. The resistance/temperature relationship
for copper wire is about 0.4% for 1°C, and with this ratio the coil
resistance increases. That is, in order to operate of the relay, it is
necessary that the voltage be higher than the pick-up voltage and
the pick-up voltage rises in accordance with the increase in the
resistance value. However, for some polarized relays, this rate of
change is considerably smaller.
Coil connection
When connecting coils of polarized relays, please check coil polarity
(+,-) at the internal connection diagram (Schematic). If any wrong
connection is made, it may cause unexpected malfunction, like
abnormal heat, fire and so on, and circuit do not work. Avoid
impressing voltages to the set coil and reset coil at the same time.
Ambient Environment
Usage, Transport, and Storage Conditions
Dew condensation
Condensation occurs when the ambient temperature drops suddenly
from a high temperature and humidity, or the relay is suddenly
transferred from a low ambient temperature to a high temperature
and humidity. Condensation causes the failures like insulation
deterioration, wire disconnection and rust etc.
Panasonic Corporation does not guarantee the failures caused by
condensation.
The heat conduction by the equipment may accelerate the cooling
of device itself, and the condensation may occur.
Please conduct product evaluations in the worst condition of the
actual usage. (Special attention should be paid when high
temperature heating parts are close to the device. Also please
consider the condensation may occur inside of the device.)
Icing
Condensation or other moisture may freeze on relays when the
temperature become lower than 0°C.This icing causes the sticking
of movable portion, the operation delay and the contact conduction
failure etc. Panasonic Corporation does not guarantee the failures
caused by the icing.
The heat conduction by the equipment may accelerate the cooling
of relay itself and the icing may occur. Please conduct product
evaluations in the worst condition of the actual usage.
Low temperature and low humidity
The plastic becomes brittle if the switch is exposed to a low
temperature, low humidity environment for long periods of time.
High temperature and high humidity
Storage for extended periods of time (including transportation
periods) at high temperature or high humidity levels or in
atmospheres with organic gases or sulfide gases may cause a
sulfide film or oxide film to form on the surfaces of the contacts and/
or it may interfere with the functions. Check out the atmosphere in
which the units are to be stored and transported.
During usage, storage, or transportation, avoid locations subjected
to direct sunlight and maintain normal temperature, humidity and
pressure conditions.
Temperature/Humidity/Pressure
When transporting or storing relays while they are tube packaged,
there are cases the temperature may differ from the allowable
range. In this case be sure to check the individual specifications.
Also allowable humidity level is influenced by temperature, please
check charts shown below and use relays within mentioned
conditions. (Allowable temperature values differ for each relays,
please refer to the relay's individual specifications.)
1) Temperature:
The tolerance temperature range differs for each relays, please
refer to the relay’s individual specifications

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE
Package
In terms of the packing format used, make every effort to keep the
effects of moisture, organic gases and sulfide gases to the absolute
minimum.
Silicon
When a source of silicone substances (silicone rubber, silicone oil,
silicone coating materials and silicone filling materials etc.) is used
around the relay, the silicone gas (low molecular siloxane etc.) may
be produced.
This silicone gas may penetrate into the inside of the relay. When
the relay is kept and used in this condition, silicone compound may
adhere to the relay contacts which may cause the contact failure.
Do not use any sources of silicone gas around the relay (Including
plastic seal types).
NOx Generation
When relay is used in an atmosphere high in humidity to switch a
load which easily produces an arc, the NOx created by the arc and
the water absorbed from outside the relay combine to produce nitric
acid.
This corrodes the internal metal parts and adversely affects
operation.
Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If
use at high humidity is unavoidable, please contact our sales
representative.
Others
Cleaning
• Although the environmentally sealed type relay (plastic sealed type,
etc.) can be cleaned, avoid immersing the relay into cold liquid (such
as cleaning solvent) immediately after soldering. Doing so may
deteriorate the sealing performance.
• Cleaning with the boiling method is recommended(The temperature
of cleaning liquid should be 40°C or lower ).
Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may
cause breaks in the coil or slight sticking of the contacts due to
ultrasonic energy.
Please refer to "the latest product specifications"
when designing your product.
