The ICM533 is a UL Listed Type 1 & 2 Surge Protective Device for Delta
High-Leg 120/240 VAC Three Phase voltage configurations. When a surge
occurs, the ICM533 will absorb the surge up to the limits expressed in
the specifications section of this guide. The ICM533 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 ICM533 has a status light on the control which identifies
operational status when illuminated. The ICM533 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).
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.

MAINTENANCE
MODE OF OPERATION
SPECIFICATIONS
The conductors used to connect the SPD shall not be any longer
than necessary and shall avoid unnecessary bends.
1. Turn off the main breaker and/or main power to the service
disconnect.
2. Verify your mains voltage and match that with ICM533 ratings.
3. Remove the cover on service disconnect or the electrical panel.
4. Mount the ICM533 through the 3/4” conduit connection of the
electrical panel.
5. Remove the retaining ring and washer on the ICM533.
6. Feed the wires into the electrical panel or service disconnect.
7. Re-secure the retaining ring and washer.
8. Route the white wire to the neutral lug and secure.
Wiring Type 1 installation
• Route the two black wires and one red wire to the appropriate L1, L2,
and L3 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.
NOTE: The red wire attaches to the high-leg.
Wiring Type 2 installation
• Route the two black wires and one red wire (L1, L2, and L3) 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.
NOTE: The red wire attaches to the high-leg.
9. Reinstall cover on service disconnect or the electrical panel.
10. Restore power; Green LED should be on indicating full protection.
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).
