CAUTION!
Installation of the ICM450A and ICM450A PLUS+ shall be performed by trained
technicians only. Adhere to all local and national electric codes.
Disconnect all power to the system before making any connections.
INSTALLATION
1. Using (2) #8 screws, mount the ICM450A and ICM450A PLUS+ in a cool, dry,
easily accessible location in the control panel.
2. Connect voltage as shown in Figure 1 (below). Leave existing line and load side
connections intact on the contactor.
3. Load side monitoring is optional (unit may be used to monitor line side only).
Wire the contactor and optional control voltage monitoring as in Figure 2.
Note: Load/line wire must be rated for the voltage applied. Do not use wire
smaller than 20 AWG.
4. Upon application of power, the ICM450A and ICM450A PLUS+ will be on line and
will begin to monitor the system.

INSTALLATION
• With "Control Mode" set to "ON," there must be a voltage present on terminals 4
and 5 for the relay output terminals 1 and 2 to close; this voltage can be supplied
from a thermostat, pressure switch, etc.
• When the voltage on these terminals is re-applied, the unit will not re-energize
until the delay on break (0-10 minutes) time has elapsed
• Use of terminals 4 and 5 is optional; they will be ignored if the "Control Mode" is
set to "OFF"
• Terminals 1 and 2 are "dry," normally open contacts
• Terminals 1 and 2 are closed when power is within specifications
• Terminals 1 and 2 open when there is a
fault condition
• Terminals 1 and 2 open when there is a loss

set to "ON"
Note 1: Terminals 6, 7 and 8 used for
ModBus communication on
ICM450A PLUS+.
Note 2: Use of female quick connect terminals
suitable for field wiring required.
Female quick-connect terminals
suitable for factory-wiring only are not permitted.

DIN RAIL MOUNTING INSTRUCTIONS
1. Align the DIN rail mounting plate with the 4 holes on the
back side of the ICM450A/450A Plus+.
2. Thread the four # 10 screws provided in the kit through
the ICM450A/450A Plus+ mounting holes from the top
side and thread into the mounting plate as seen in fig 5.
** Optional din rail mounting kit sold separately

Voltage Read Calibration
Hold down both the UP & Down buttons simultaneously to enter calibration
mode (Fault and Setup LEDs will flash). Press the Up & Down buttons individually
to adjust display voltage allowing a few seconds between presses for voltage
averaging. Press SETUP to exit calibration
