GENERAL INSTALLATION
CAUTION: Remove all power at the main service panel before
installing or servicing the 3VMS by switching off the appropriate
breaker or removing the appropriate fuse.
1. With the 3VMS enclosure in a vertical position, drill an
appropriately sized hole for the waterproof whip (NEMA rated
waterproof wire raceway) you will be using.
2. Mount the appropriate NEMA rated waterproof wire raceway to
the 3VMS enclosure.
3. Mount the four feet which come with the enclosure to the four
corner holes in the bottom of the enclosure.
4. Lay the 3VMS against the desired mounting location and using
the appropriate hardware, fasten the 3VMS to the desired
location through the holes in the feet.
5. Connect the line voltage wires to the contactor's input (L1, L2 and
L3) and wire your equipment load wires to the contactor output
(T1, T2 and T3) as seen in the System Diagram.
6. Connect the incoming source ground to the ground bus. Attach a
ground wire from the ground bus to the chassis ground.
IMPORTANT SAFETY INFORMATION
WARNING! : ELECTRICAL SHOCK HAZARD – Before
installing this unit, turn off power at the main service
panel by removing the fuse or switching the appropriate
circuit breaker to the OFF position.
• This control should be installed by a trained professional
• Incorrect installation can cause personal injuries, property
damage or even death.
• Follow all local & national codes while installing control.
• WARNING — No Serviceable Parts (Attention: Aucune pièce
remplaçable ou reparable).
WARNING — Shock hazard — Do not open (ATTENTION –
•
RISQUE DE CHOC – NE PAS OUVRIR).

between presses for voltage averaging. Press READ to exit calibration.
3VMS
GENERAL OPERATIONS
Upon installation and application of power, the 3VMS from ICM Controls
will monitor the incoming line voltage for variations including phase loss,
phase reversal, phase unbalance and over/under voltage conditions
while providing continuous surge protection. If the voltage parameters
are within the preset limits of the voltage monitor, the 3VMS will close the
onboard contactor and power the load. If there is an over/under voltage,
phase loss, phase reversal or phase unbalance caused by incoming
voltage varying outside the preset parameters, the contactor will open
and will not close again until the voltage parameters are back in range.
The parameters of the ICM450A voltage monitor can be customized for
specifi c operation but it is recommended to leave them at the preset
values.
WARNING! Do not set the voltage setpoint of the ICM450A above
240VAC and no more than 10% over voltage or potential damage
to 3VMS could occur.
The 3VMS will constantly monitor voltage surges and suppress surges
within the limits of the ICM530 specifi cations. Once surge suppression
capability is compromised, the LED on the ICM530 will stop illuminating
and the ICM530 will require replacement.
