ICM CONTROLS ICM518 Surge Protective Device
Please follow all State, Local and National electrical codes when installing this product. Installation should only be done by a licensed electrician for Type 1 devices or a licensed HVAC technician for Type 2 devices.
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.
- WARNING — No Serviceable Parts (Attention: Aucune pièce remplaçable ou reparable).
- WARNING — Shock hazard — Do not open (ATTENTION – RISQUE DE CHOC – NE PAS OUVRIR).
Maintenance
Periodically check the LED status on the SPD. If the Greenlight is OFF, the
protection is no longer available and the SPD needs to be replaced
immediately. 12 AWG stranded copper wire or larger required. Product contains
no serviceable parts. This device features an internal protection that will
disconnect the surge protective component at the end of its useful life but
will maintain power to the load – now unprotected.
Mode of Operation
The ICM518 is a UL Listed Type 1&2 Surge Protective Device for 240 VAC Split
Phase voltage configurations. When a surge occurs, the ICM518 will
absorb the surge up to the limits expressed in the specifications section of
this guide. The ICM518 incorporates thermal protection on the surge elements
(TMOV’s) which allows for safe disabling of the surge elements when a surge
exceeds the thermal limits of the device. The ICM518 has a status light on
the control which identifies operational status when illuminated. The ICM518
can be installed as a Type 1 or Type 2 device for both indoor and outdoor
applications. Suitable for use on a circuit capable of delivering not more
than 200kA RMS symmetrical amperes, 240V maximum (Convient à des circuits
produisant au plus 200kA RMS A eff.”, 240V maximum).
Installation Instructions
The conductors used to connect the SPD shall not be any longer than necessary and shall avoid unnecessary bends.
-
Turn off the main breaker and/or main power to the service disconnect.
-
Verify your mains voltage and match that with ICM518 ratings.
-
Remove the cover on service disconnect or the electrical panel.
-
Mount the ICM518 through the 3/4” conduit connection of the electrical panel.
-
Remove the retaining ring and washer on the ICM518.
-
Feed the wires into the electrical panel or service disconnect.
-
Re-secure the retaining ring and washer.
-
Route the white wire to the neutral lug and secure.
Wiring Type 1 installation
Route the two black wires to the appropriate L1 and L2 connections before the breaker panel as seen in the wiring diagram for Type 1 installation and according to your local, state, and national electrical codes.
Connect the white wire to the Neutral Bus
Wiring Type 2 installation
Route and connect the two black wires (L1 and L2) to the individual breakers on the circuit breaker panel as seen in the wiring diagram for Type 2 installation and according to your local, state and national electrical codes.
Connect the white wire to the Neutral Bus. -
Reinstall cover on service disconnect or the electrical panel.
-
Restore power; Green LED should be on indicating full protection.
