ICM CONTROLS ICM493 Programmable Single-Phase Voltage Monitor Installation
Guide
INSTALLATION
-
Remove cover by extracting the screw from the bottom of the enclosure.
-
Remove desired size knock-outs for conduit from the enclosure (1/2” or 3/4”).
-
Mount the enclosure to the desired surface.
-
Attach input and output conduit, apply strain relief.
-
Tilt front panel diagonally and insert the panel into the enclosure, as shown in Figure 1.
-
Lay the front panel horizontally in the enclosure and align the holes on the side, as shown in Figure 2.
-
Using the two larger screws, included in the kit, and a screwdriver, attach the front panel to the enclosure.
-
Wire L1 and L2 directly to the contactor input and output, as shown in Figure 3.
-
Close the hinged plate and secure the upper right corner into the bracket with the small screw provided in kit.
-
Once settings have been configured, attach cover and secure with screw.
CALIBRATION FEATURE
The ICM493 can be calibrated to match the reading from a true RMS meter.
- Measure input voltage from T1 to T2 using a true RMS meter.
- Hold buttons simultaneously until line voltage starts to flash.
- Adjust voltage using buttons to match measured voltage from step 1.
- Push button to lock values into memory.
