GUIDELINES FOR USAGE
■ For cautions for use, please read " GUIDELINES FOR RELAY USAGE ".
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
■ Cautions for usage of LD-P relays
● Max. applied voltage and temperature rise
Proper usage requires that the rated voltage be impressed
on the coil. Note, however, that if a voltage greater than
or equal to the maximum applied 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.

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
■ Coil connection
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, longterm 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.
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.
■ 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 operate 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 ℃,
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 operate voltage and the
operate voltage rises in accordance with the increase
in the resistance value. However, for some polarized
relays, this rate of change is considerably smaller.

Ambient Environment
■ 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 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
2) Humidity: 5 to 85 % RH
Humidity (% RH)

Allowable range
Avoid icing

temperatures
lower than 0°C
Avoid condensation when
used at temperatures higher

0
●Low temperature and low humidity
The plastic becomes brittle if the relay 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.
●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.

-40
●Icing
Condensation or other moisture may freeze on relays
when the temperature become lower than 0 ℃.This
icing causes the sticking of movable portion, the
operation delay and the contact conduction failure etc.
Panasonic Industry Co., Ltd. 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.
85
Ambient temperature (℃)
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 Industry Co., Ltd. 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. )
●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 sealed 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 ℃ ). If use at high humidity is unavoidable,
please contact our sales representative.

■ 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 ℃ 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.
