GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE
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 a󰀨ected 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 di󰀨ers for
each relays, please refer to the relay's individual specications.
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, re and so on, and circuit do not work. Avoid
impressing voltages to the set coil and reset coil at the same time.
Usage, Transport, and Storage Conditions
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 di󰀨er from the
allowable range. In this case be sure to check the individual
specications. Also allowable humidity level is inuenced by
temperature, please check charts shown below and use relays
within mentioned conditions. (Allowable temperature values
di󰀨er for each relays, please refer to the relay's individual
specications.)
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
(Hot start)
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.
Precautions for Coil Input
Ambient Environment
For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
1) Temperature:
The tolerance temperature range differs for each relays,
please refer to the relay’s individual specifications
2) Humidity:
5 to 85 % RH
3) Pressure:
86 to 106 kPa
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 sulde gases may cause a sulde lm or oxide lm 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.

GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE
Package
In terms of the packing format used, make every e󰀨ort to keep the
e󰀨ects of moisture, organic gases and sulde gases to the absolute
minimum.
Silicon
When a source of silicone substances (silicone rubber, silicone oil,
silicone coating materials and silicone lling 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).
Others
Cleaning
1) 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.
2) 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 specications"
when designing your product.

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 a󰀨ects 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.
