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 field replaceable 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 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.).

REPLACES

• 30A: Mars: 83916, RectorSeal: RSH-50 96417
• 60A: Mars: 83915, RectorSeal: RSH-50 96419
• All standard disconnect boxes rated for equal voltage and current configurations

Please follow all State, Local and National electrical codes when installing this product. Installation should only be done by a licensed HVAC technician for Type 2 devices.

As covered by NEC 110.20 and UL’s listing requirements, field replacement of the SPD module in this product constitutes restoring an equipment to operating condition and is considered a modification of the product’s UL Listing (certification).

DIAGNOSTICS AND MAINTENANCE

Periodically check the status on the SPD. If the green light is OFF, the protection is no longer available and the SPD portion (ICM495-SPD) needs to be replaced immediately (see SPD replacement section of this guide). 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. If this situation is undesirable for the application, follow the manufacturer’s instructions for replacing the device. 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 14 AWG stranded copper wire rated for the appropriate voltage being used. 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).

1. Make sure the 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 labeled 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.

ICM495-60A (NON-FUSED)

Use 14 AWG stranded copper wire rated for the appropriate voltage being used. Use wiring suitable for 75/90°C (Utiliser un câblage convenant à 75/90°C).

1. Make sure the 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 labeled 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.

SPD REPLACEMENT INSTRUCTIONS

(FUSED DISCONNECT)

1. Disconnect power before servicing! Failure to disconnect power can result in personal injury or death.
2. Remove the pull out shunt. Remove the insulating barrier. Pry at upper right corner and upper left corner of cover. Some force is required.
3. Remove the SPD power wires from the left and right line terminals on the fused disconnect and remove the SPD ground wire from the ground terminal block on the fused disconnect.
4. Remove the fuses and remove the mounting screws on the line voltage terminal block.
5. Slide the line voltage terminal block down until it touches the top of the fuse holders. This allows room to remove the SPD.
6. Remove the mounting screws on the SPD. Grasp the wires of the SPD and pull up and out thus removing the old SPD.
7. Replace the old SPD with the new SPD in reverse order. Re-insert and tighten the mounting screws to hold down the new SPD.
8. Re-install the line voltage terminal block and tighten the screws.
9. Re-install the fuses if functional or replace the fuses.
10. Re-wire the black wires of the SPD to the left and right line terminals of the fused disconnect and re-wire the SPD ground wire to the ground terminal block of the fused disconnect.
11. Check all wiring is correct and secure including the source and load wiring.
12. Replace the top closeout cover and reinsert the pullout shunt

11. Replace the top closeout cover and reinsert the pullout shunt.

WARNING!
FOR FUSED & NON-FUSED DISCONNECTS

The field replacement of the SPD will 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. The field evaluation body will apply a field label on to the product to indicate that the product has been evaluated, and issue a report to AHJ.
