The ICM530 is a UL Listed Type 1&2 Surge Protective Device for three phase
Delta 240 VAC or Wye 120/208 VAC three phase voltage configurations.
When a surge occurs, the ICM530 will absorb the surge up to the limits
expressed in the specifications section of this guide. The ICM530
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 ICM530 has a status light on the control
which identifies operational status when illuminated. The ICM530 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. Determine if you have a Wye or Delta configuration.
3. Verify your mains voltage and match that with ICM530 ratings.
4. Remove the cover on service disconnect or the electrical panel.
5. Mount the ICM530 through the 3/4” conduit connection of the
electrical panel.
6. Remove the retaining ring and washer on the ICM530.
7. Feed the wires into the electrical panel or service disconnect.
8. Re-secure the retaining ring and washer.
9. Route the white wire to the neutral lug and secure.
Wiring Type 1 installation
• Route the three black wires to the appropriate L1, L2, 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.
• There will be a white wire which is only used in the Wye configuration
and which needs to be capped off in the Delta configuration.
Wiring Type 2 installation
• Route and connect the three black wires (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.
• There will be a white wire which is only used in the Wye configuration
and which needs to be capped off in the Delta configuration.
10. Reinstall cover on service disconnect or the electrical panel.
11. 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).
