Other Precautions
1. General notice:
Turn off the power to the relay before starting installation, removal, wiring,
maintenance, and inspection of the relays. Failure to turn power off may
cause electrical shock or fi re hazard.
Observe specifi cations and rated values, otherwise electrical shock or fi re
hazard may be caused.
Use wires of the proper size to meet voltage and current requirements. Tight-
en the terminal screws on the relay socket to the proper tightening torque.
Surge absorbing elements on AC relays with RC or DC relays with diode are
provided to absorb the back electromotive force generated by the coil. When
the relay is subject to an excessive external surge voltage, the surge absorb-
ing element may be damaged. Add another surge absorbing provision to the
relay to prevent damage.
To maintain the initial characteristics, do not drop or shock the relay.
The relay cover cannot be removed from the base during normal operation. To
maintain the initial characteristics, do not remove the relay cover.
Use the relay in environments free from condensation, dust, sulfur dioxide
(SO
Make sure that the coil voltage does not exceed applicable coil voltage range.

2. UL and CSA ratings may differ from product rated values determined by IDEC.
3. Do not use relays in the vicinity of strong magnetic fi eld, as this may affect
Before operating the latching lever of the RU relay, turn off the power to
the RU relay. After checking the circuit, return the latching lever to the
original position.
Do not use the latching lever as a switch. The durability of the latching lever
is a minimum of 100 operations.
When using DC loads on 4PDT relays, apply a positive voltage to terminals of
neighboring poles and a negative voltage to the other terminals of neighbor-
ing poles to prevent the possibility of short circuits.
DC relays with a diode have a polarity in the coil terminals. Apply the DC volt-
age to the correct terminals.
