HIGH VOLTAGE WARNING! – Turn o power at the
main service panel before installing.
1. Remove cover by extracting the screw from the bottom of the
enclosure.
2. Remove desired size knock-outs from the enclosure needed to
install the required conduits (1/2” or 3/4”).
3. Mount the enclosure to the desired surface with (4) screws and
pull any conduits through the knockouts on the bottom as needed
(refer to Figure 0).
4. Rest the front panel door in a vertical position using the contactor
bracket as a base of support as seen in Figure 1.
5. Hold the contactor and unscrew the two Phillips head mounting
screws on the front of the panel also seen in Figure 1.
6. Whilst holding the contactor against the front panel, lay the front
panel face down as seen in Figure 2.
7. Rotate the contactor 90 degrees counter clockwise and rest it on
its base as seen in Figure 3. This orientation will give you access
to the L1, L3 and T1, T3 terminal screws which are needed to mount
the heavy gauge wires of the 60 AMP circuit. CAUTION: DO NOT
USE THE ¼” QUICK CONNECT TERMINALS IN A 60 AMP CIRCUIT.
8. Insert the line wires from the incoming power to the L1 & L3
terminals and tighten down the screws as seen in Figure 4.
9. Insert the load (equipment) wires to T1 & T3 and tighten down the
screws as seen in Figure 5.

INSTALLATION
10. Rotate the contactor 90° clockwise, then rotate the whole front
panel and contactor assembly 180° counter clockwise so the front
panel is facing up and the contactor is resting on its side as seen in
Figure 6.
11. Adjust the position of the contactor to align the mounting bracket
threaded holes with the front panels through holes also seen
in Figure 6.
12. Re-insert the two Phillips head screws which secure the contactor
to the front panel and tighten down securely seen again in Figure
6.
13. Tilt front panel diagonally and insert the panel into the enclosure
as seen in Figure 7.
14. Lay the front panel horizontally in the enclosure and align the
holes on the sides of the case one at a time also seen in Figure 7.
15. Using the two larger screws included in the kit, attach the front
panel to the enclosure as seen in Figure 8, (do not overtighten
screws).
16. Close the hinged front plate and secure the upper right corner
into the bracket with the small screw provided in kit as seen in
Figures 9 & 10.

4. Maintenance Features

The ICM493-60A is a programmable, single-phase voltage monitor with surge protection, designed for industrial and commercial applications. It provides comprehensive protection against various power anomalies and offers advanced monitoring and control features.

Function Description

The device monitors line voltage and protects equipment from over/under voltage conditions, short cycles, and power surges. It features a control board with terminals (T1, T2, T3, T4) for wiring and a user interface for setting parameters and viewing status. The ICM493-60A is designed for outdoor installation and is housed in a NEMA/Type 3R rain-tight enclosure.

Important Technical Specifications

• Input:
  • Voltage: 195-264 VAC
  • Frequency: 50/60 Hz
• Contact Ratings:
  • Voltage: 240 VAC
  • Full Load Amps (FLA): 60A
  • Locked Rotor Amps (LRA): 360A
• Control Operating Temperature:
  • Operating: -40°F to 167°F (-40°C to 75°C)
  • Storage: -40°F to 185°F (-40°C to 85°C)
  • LCD Operating: -4°F to 167°F (-20°C to 75°C)
• Mechanical:
  • Mounting: Four mounting holes in the back of the enclosure.
  • Enclosure: NEMA/Type 3R, rain-tight enclosure rated for outdoor installation.
  • Dimensions: 8"L x 10"W x 6"H
• Parameters (Adjustable):
  • Line voltage: 200-240 VAC (adjustable, default 240 VAC, recommended nameplate voltage).
  • Over/under voltage setting: 5%-10% (adjustable, default 10%, recommended 10% over/under). Under voltage is limited to 195 VAC.
  • Anti-short cycle time delay: 0.5-10 minutes (adjustable, default 0:30, recommended 4 minutes). This is the delay between the end of a fault and the closing of the contactor.
  • Number of trials (Reset mode retries): 1-5, Auto (adjustable, default Auto, recommended Auto). Auto has unlimited retries.
  • Allowed MOV fail (Number of surge devices allowed to fail while maintaining operation): 0-5 (adjustable, default 5, recommended 5 for ensured operation, or 4 for maximum operation while ensuring surge protection).

Usage Features

• Installation:
  • The enclosure is designed for easy installation with knockout provisions for conduit entry (1/2" or 3/4").
  • The control board is mounted with screws and can be removed for easier wiring.
  • Wiring involves connecting line power to T1 and T2, and load power to T3 and T4.
  • The device uses 75°C copper wire only.
  • It is crucial to verify the voltage warning and turn off power at the main service panel before installation.
• Setting Parameters:
  • The SETUP button is used to scroll through user-configurable settings.
  • The UP and DOWN arrow buttons are used to change the set point.
  • After setting the last parameter, the device returns to the Read screen.
• Button Functions:
  • SETUP: Enters setup mode and toggles through configurable settings.
  • READ: Returns to the Read screen, displaying faults, current line voltage, and remaining MOVs.
  • FAULT: Scrolls through past recorded faults. Holding for 5 seconds clears fault memory.
  • UP/DOWN Arrows: Adjusts settings and performs line voltage calibration.
  • SETUP + FAULT (Hold for 2 seconds): Resets the unit.
• Calibration Feature:
  • The ICM493-60A can be calibrated to match a true RMS meter.
  • To calibrate, measure input voltage from T1 to T2 with a true RMS meter.
  • Hold the UP and DOWN buttons simultaneously until the line voltage starts to flash.
  • Adjust the voltage using the UP or DOWN buttons to match the measured voltage.
  • Push the SETUP button to lock the values into memory.

Maintenance Features

• Fault Monitoring: The device records past faults, which can be reviewed using the FAULT button.
• Fault Memory Clear: Fault memory can be cleared by holding the FAULT button for 5 seconds.
• Unit Reset: The unit can be reset by holding the SETUP and FAULT buttons simultaneously for 2 seconds.
• MOV Monitoring: The device monitors the number of remaining MOVs (Metal Oxide Varistors), which are surge protection components. This allows users to track the health of the surge protection system. The "Allowed MOV fail" parameter can be set to allow operation even if some MOVs have failed, providing flexibility in maintenance and operation.
