Product Usage Instructions

Installation Instructions

1. Ensure all power to the disconnect is off and the pull-out shunt is removed.
2. Connect the ground wire (G) of the SPD to the ground terminal block (GND) and connect ground wires from the source and load to the GND terminal block.
3. Connect line wires (A & B) to line terminals on the disconnect’s terminal block labelled line.
4. Connect SPD wires C & D to the Left (L) and Right (R) line terminals of the disconnect box.
5. Connect Load wires (E & F) to the Left (L) and Right (R) Load terminals of the disconnect box.
6. Install the disconnect box vertically with the cover facing forward and the drain hole at the bottom.

Diagnostics and Maintenance
For any diagnostics or maintenance, ensure compliance with State, Local, and National electrical codes. Field replacement of the SPD requires evaluation by a UL-certified engineer or a competent field evaluation body.

MODE OF OPERATION

The ICM495 is a UL Listed Electrical Disconnect with an Internal Surge Protective Device built-in. The ICM495 is available in two models 30A Fused and 60A Non-Fused.
The included Type 2 SPD is intended for 240 VAC Split Phase configurations. When a surge occurs, the ICM495 will absorb the surge up to the limits expressed in the specifications section in this guide. The ICM495 incorporates thermal protection on the surge elements

(TMOV’s) which allows for the safe disabling of the surge elements when a surge exceeds the thermal limits of the device. The ICM495 has a status light on the control which identifies operational status when illuminated. The ICM495 can be installed as a Type 2 device for both indoor and outdoor applications. Suitable for use on a circuit capable of delivering not more than 10kA RMS symmetrical amperes (Convient à des circuits produisant au plus 10kA eff.).

DIAGNOSTICS AND MAINTENANCE

Periodically check the status on the SPD. If the green light is OFF, the protection is no longer available and the unit needs to be replaced immediately. This device features 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. 14 AWG stranded copper wire or larger required. If any of the 30 Amp fuses blow on the fused model, please replace the fuse or fuses with the appropriate 30 amp fuses. Note: the ICM495-60A model does not accommodate fuses.

INSTALLATION INSTRUCTIONS

ICM495-30A (FUSED)

Use 8 – 14 AWG wire for ground and 2-14 AWG wire for Line and Load. Replace fuses with 30 Amp fuses rated at the appropriate voltage being used. Use wiring suitable for 75/90°C (Utiliser un câblage convenant à 75/90°C). Torque all connectors to 37.5 in-lbs.

1. Make sure all power to the fused disconnect is off and the pull-out shunt is removed.
2. Connect the ground wire (G) of the SPD to the ground terminal block (GND). Also, connect the ground wires from the source and LOAD to the GND terminal block.
3. Connect the line wires (A & B) to the line terminals on the terminal block of the disconnect labelled line.
4. Connect the SPD wires C & D to the Left (L) and Right (R) line terminals of the fused disconnect box.
5. Connect the Load wires (E & F) to the left (L) and Right (R) Load terminals of the fused disconnect box.
   NOTE: To meet the NEMA 3R rating, the disconnect box needs to be installed vertically with the cover facing forward and the drain hole in the bottom facing down.

WARNING! FOR FUSED & NON-FUSED DISCONNECTS
ELECTRICAL SHOCK HAZARD – Disconnect all power before servicing or installing. Installation should only be performed by trained and licensed technicians. Always follow all state and national electrical codes upon installation and service.

ICM495-60A (NON-FUSED)

Use 8 – 14 AWG wire for ground and 2-14 AWG wire for Line and Load. Use wiring suitable for 75/90°C (Utiliser un câblage convenant à 75/90°C). Torque all connectors to 37.5 in-lbs.

1. Make sure all power to the disconnect is off and the pull-out shunt is removed.
2. Connect the ground wire (G) of the SPD to the ground terminal block (GND). Also, connect the ground wires from the source and LOAD to the GND terminal block.
3. Connect the line wires (A & B) to the line terminals on the terminal block of the disconnect labelled line.
4. Connect the SPD wires C & D to the Left (L) and Right (R) line terminals of the disconnect box.
5. Connect the Load wires (E & F) to the left (L) and Right (R) Load terminals of the disconnect box.

NOTE : To meet the NEMA 3R rating, the disconnect box needs to be installed vertically with the cover facing forward and the drain hole in the bottom facing down.

WARNING! FOR FUSED & NON-FUSED DISCONNECTS
The field replacement of the SPD would require a field evaluation by a UL- certified engineer or a competent field evaluation body, to determine compliance of the product and approval of the installation.
