## HANDLING 

- ■Mounting method of relay 

- 1) Match the direction of relay and socket. 

**==> picture [60 x 93] intentionally omitted <==**

- 2)  Insert both ends of the relay securely all the way in until both hooks clear the ribs on the relay case. 

**==> picture [140 x 63] intentionally omitted <==**

- ■Removing method of relay 

- 1) Remove the relay, applying force in the direction shown below. 

**==> picture [65 x 80] intentionally omitted <==**

- 2)  In case there is not enough space for finger to pick relay up, use screwdrivers in the way shown. 

**==> picture [75 x 109] intentionally omitted <==**

- 3) When using the removal key ( APA801 ) , remove the relay as shown in the figure. You can purchase the removal key ( APA801 ) as an accessory.

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE 

■For cautions for use, please read " GUIDELINES FOR RELAY USAGE ". https://industry.panasonic.com/global/en/products/control/relay/cautions_use 

## 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, 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. 

## ■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. 

## ■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. 

## ■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.

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE 

## 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 

**==> picture [166 x 142] intentionally omitted <==**

**----- Start of picture text -----**<br>

- 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. ) 

## ●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. 

- ●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. 

## ●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.

## 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 ℃ 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.
