IMPORTANT SAFETY INFORMATION
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.
Always shut off internal breaker before servicing connected
equipment.
• 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.
GENERAL INSTALLATION
CAUTION: Remove all power at the main service panel before
installing or servicing the Sentry 3N1 by switching off the
appropriate breaker or removing the appropriate fuse. Also
make sure the service disconnect breaker on the sentry 3N1 is
in the OFF position.
1. With the Sentry 3N1 enclosure in a vertical position, drill an
appropriately sized hole for the appropriate waterproof whip (NEMA
rated waterproof wire raceway) you will be using.
2. Mount the appropriate NEMA rated waterproof wire raceway to the
Sentry 3N1 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 Sentry 3N1 against the desired mounting location and using
appropriate hardware, fasten the Sentry 3N1 to the desired location
through the holes in the feet.
5. Bring Line voltage 208/240VAC power wires to the breaker switch
input and wire your equipment load wires to the contactor output as
seen in the diagram below.

GENERAL OPERATIONS GENERAL OPERATIONS
Upon installation and application of power, the Sentry 3N1 from ICM Upon installation and application of power, the Sentry 3N1 from ICM
controls will monitor the incoming line for voltage variation and surges. controls will monitor the incoming line for voltage variation and surges.
If the voltage is within the preset limits of the voltage monitor, the Sentry If the voltage is within the preset limits of the voltage monitor, the Sentry
3N1 will close the onboard contactor and power the load. If there is an 3N1 will close the onboard contactor and power the load. If there is an
over or under voltage condition caused by incoming voltage varying over or under voltage condition caused by incoming voltage varying
outside the preset limits, the contactor will open and will not close outside the preset limits, the contactor will open and will not close
again until the voltage is back within range. The parameters of the
ICM492 voltage monitor can be customized for specifi c operation but it is
recommended to leave them at the preset values.
CAUTION: Do not set the voltage setpoint of the ICM492 above
240VAC and no more than 5% over voltage or potential damage
to Sentry 3N1 could occur.
The Sentry 3N1 will constantly monitor voltage surges and suppress
surges within the limits of the ICM517A specifi cations. Once surge
suppression capability is compromised, the LED on the ICM517A will stop
illuminating and the ICM517A will require replacement.

Trouble shooting tips
1. Check to see if incoming voltage is out
of range from the voltage settings on
the ICM492.
2. Check the control mode is turned off in
the set-up menu of the ICM492.
3. Make sure the control is not in a short
cycle delay.
4. Check your fault history to see if you are
currently in a fault condition.
5. Check contactor coil voltage and
contactor operation and replace
contactor if defective.
1. Check wiring to make sure no wires are
loose or broken
2. Replace the ICM517A because the surge
elements (TMOV'S) are spent
