INSTALLATION MODE OF OPERATION
1. Disconnect or turn off power.
2. Tapoffthemain3-phaselinevoltageandruneld-installedwirestothe
ICM409 control.
3. Theeld-installedwiresshouldhave1ampfuses(ratedforthevoltage
being used) installed in series with the ICM409.
4. Connecttheeld-installedwirestotheL1,L2,andL3screw-down
connections.
5. Set the DOM time delay to a minimum for testing purposes.
6. Break one line of the control circuit and connect to the COM and N.O.
screw-down connections on the ICM409.
7. The N.C. connection can be used as an alarm output.
8. Reapply or reconnect power.
9. After the DOM time delay, the unit should energize and the Green
(load) LED should light.
10. If the Red (status) LED is on solid, reverse any 2 line voltage wires at
the ICM409. DO NOT CHANGE THE WIRING SEQUENCE TO THE
CONTACTOR OR MOTOR/COMPRESSOR.
11. IftheRed(status)LEDisashing,makesurethevoltageand
unbalance levels are set correctly.
12.Setallparametersaccordingtomanufacturer’sspecications.
Designed in a small, easy-to-mount, DIN
Rail style case, the ICM409 continuously
monitors the incoming line voltage for errors.
When the line voltage is appropriate, the
ICM409 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 up and the red
LEDwillash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 due to noise.
STATUS LED INDICATORS
• GREEN LED = Load ON
