CAUTION:
1. The use of any coil voltage less than the rated coil voltage may compromise the operation of the relay.
2. Pickup and release voltages are for test purposes only and are not to be used as design criteria.
3. When testing, coil terminals should be connected if coil transient suppression is installed in relay.
