533 Surge Protective Device for
3-Phase Delta High-Leg 120/240 VAC

ICM533 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 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).

Installation Instructions

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.

Wiring Diagrams – Delta Configuration

Note 1:
For the ease of checking the SPD protection status, the LED display should face outwards after installation has been complete.
Note 2:
ICM533 is a Type 1 and 2 SPD, designed to be compatible with 3-phase Delta and 3-phase Wye voltage configuration. Please check your supply voltage configuration and voltage levels before installing the ICM533 per wiring diagram.
Note 3:

• When installing the Surge Protecting Device (SPD), avoid sharp bends in the conduit and long line sets.
• Keep the mounting conduit straight and short in length.
