ATTENTION: The ratings of the EC4 Current Monitoring Relay’s
output and trip relay must not be exceeded. If the coil current or
voltage of the contactor exceeds the relay’s ratings, an
interposing relay must be used.
ATTENTION: When the power is applied to the EC4 Current
Monitoring Relay (DeviceNet terminals V+ and V-), the N.O. trip
relay contact across terminals 95 and 96 will close after
approximately 2.35 seconds if no trip condition exists.
