Important Safety Information
HIGH VOLTAGE WARNING! – Turn off power at the
main service panel before installing.
Specifications
Input
• Line Voltage: 190 – 630 VAC
• Frequency: 50 – 60 Hz
• Load Side Monitoring: Optional
• Control Voltage: 18 – 240 VAC
Control Operating Temperature
• Operating Temperature: -40°F to 167°F (-40°C to 75°C)
• Storage Temperature: -40°F to 185°F (-40°C to 80°C)
LCD Operating Temperature
• Operating Temperature: -4°F to 167°F (-40°C to 75°C)
Mechanical
• Mounting: Surface mount using two (2) #8 screws
• Terminations: Screw terminals
• Dimensions: 5.5"L x 4.5"W x 1.5"H
Parameters
Phase Unbalance Protection
• Voltage Unbalance: 2-20%, adjustable
Over/Under Voltage
• Under Voltage: 2-25%, adjustable
• Over Voltage: 2-25%, adjustable
Phase Loss Protection
• Phase Loss Condition: Equals 25% of nominal for any given phase; system will
shut down and a fault will be recorded if this should occur.
Delay on Break Timer
• Control Voltage: 18-240 VAC
• Time Delay: 15 seconds to 10 minutes
Fault Interrogation Delay
• Time Delay: 0 – 15 seconds, adjustable
• Provides a delay between fault detection and system shutdown—helps to eliminate
nuisance trips and unnecessary shutdowns.
Installation
1. Turn off power at main service panel.
2. Using two (2) #8 screws, mount the ICM455 in a cool, dry, easily accessible
location in the control panel.
3. Connect voltage as shown in "Wiring Diagram". Leave existing line and load side
connections intact on the contactor.
4. Load side monitoring is optional (unit may be used to monitor line side only). Wire
the contactor and optional control voltage monitor as shown in "System Diagram".
Note: Load/line wire must be rated for 3-phase voltage rating, 20ga minimum.
5. Upon application of power, the ICM455 will be on line and will begin to monitor
the system.
Note: If voltage is not correct, see "Voltage Read Calibration" in Button
Functions section
• Terminals 3 and 4 are the control signal input terminals.
• "Control Mode" is turned ON or OFF in setup.
• With "Control Mode" set to ON, there must be a voltage present on terminals 3
and 4 for the relay output terminals 1 and 3 to close; this voltage can be supplied
from a thermostat, pressure switch, etc.
• When the voltage on theses terminals is re-applied, the unit will not re-energize
until the delay on break (0-10 minutes) time has elapsed.
• Use of terminals 3 and 4 is optional; they will be ignored if the "Control Mode" is
switched to OFF.
• Terminals 1 and 3 are "dry", normally open contacts.
• Terminals 1 and 3 are closed when power is within specifications.
• Terminals 1 and 3 open when there is a fault condition.
• Terminals 1 and 3 open when there is a loss of the control signal with "Control
Mode" set to ON.
• Auxiliary terminals will be used in future models.
Output
• Type: Relay, SPDT
• Voltage Range: 240 VAC at 10A max
• Frequency: 50 – 60 Hz
• Remote Monitor Voltage: 0 – 10 VDC
