Other Precautions

1. General notice: 2. UL and CSA ratings may differ from product rated values determined by IDEC.
To maintain the initial characteristics, do not drop or shock the relay.
3. Do not use relays in the vicinity of strong magnetic fi eld, as this may affect Switches & Pilot Lights
The relay cover cannot be removed from the base during normal operation. To relay operation.

Use the relay in environments free from condensation, dust, sulfur dioxide
(SO ), and hydrogen sulfi de (H S).
