1. Disconnect or turn off power.
2. Tap off the main 3-phase line voltage and run field-installed
wires to the ICM408 control.
3. Connect the field-installed wires to the L1, L2 and L3
connections.
4. Set the DOM time delay to a minimum for testing purposes.
5. Break one line of your control circuit and connect to the
COM and N.O. connections on the ICM408.
6. The N.C. connection can be used as an alarm output.
7. Reapply or reconnect power.
8. After the DOM time delay, the unit should energize and the
green (load) LED should light.
9. If the red (status) LED is on solid, reverse any 2 line
voltage wires
at the ICM408
.
DO NOT CHANGE THE
WIRING SEQUENCE TO THE UNIT
.
10. If the red (status) LED is flashing, make sure the voltage
and unbalance levels are set correctly.
The ICM408 continuously monitors the
incoming line voltage for errors. When the line
voltage is appropriate, the ICM408 closes a set
of N.O. contacts and lights a green LED. When
the incoming voltage is outside of the user-set
parameters, the N.O. contacts open and the
red LED will flash a code for the particular fault
present. The control will also interrogate the
line voltage during the fault condition to avoid
short cycling and nuisance trips.
