Precautions for Safe Use

Electric Shock

Please do not touch the relay terminal (live parts) or socket terminal (live parts) while the power is on. This may lead to electric shock.

Wiring

When wiring, please be sure to turn off the power. Also, while the power is on, please keep the cover closed and do not touch the terminal.

Please apply the correct voltage to the input terminal. If the correct voltage is not applied, regular functions may not run, and this may lead to damage or fire to the product.

For Relay Type

Please do not use at loads exceeding contact ratings such as for the number of openings and closings (contact current, contact voltage) etc.. This can lead to reduced performance in terms of poor insulation, contact welding, and loose connections etc., and may cause damage or fire to the relay.

The durability of relays varies significantly based on the opening and closing conditions. Before use, please perform a system check under real operating conditions, and then open and close up to the number of times that works without failure. If use is continued after performance has deteriorated, this may cause dielectric breakdown between circuits or fire damage to the relay.

Please do not use in an environment with flammable or explosive gases. This may lead to fire or explosions caused by an arc when switching contacts or the heat that a relay generates.

Non-contact Output (Transistor relay, Power MOS FET Relay and SSR)

Please do not use for the loads that exceed the rated output current. This can cause destruction of the output element, leading to a short-circuit failure or an open failure.

When using a direct current inductive load, be sure to connect a diode that can handle the reversed voltage. Otherwise, this may cause the destruction of an output element due to a reversed voltage or a short-circuit failure or an open failure.
