Make sure the IC Series is fully disconnected from the battery bank and no AC power is connected to the Inverter/Charger before commencing any AC wiring connections.

Tighten terminal blocks on both sides periodically to correct torque specs.

AC INPUTS WIRING (50A Dual IN, Dual Out Configuration)

• Remove the AC cover plate.
• Route the wires: IN1 (Hot1), IN2 (Hot2), ACN-IN (neutral), and Ground from the main panel through the AC Input strain relief clamp. Tighten the strain relief clamp securely on the wires. Always leave a little extra slack in the wiring.
• Connect the HOT1 wire (black) from the main panel to the Inverter/Chargers IN1 terminal. Connect the HOT2 wire (red) from the main panel to the Inverter/Charger’s IN2 terminal. Tighten the terminals securely, to 16 in lbf (1.8 N-m). Note: To use the Battery Charger, IN1 must always be connected to an AC Input.
• Connect the NEUTRAL (white) from the main panel to the Inverter/Chargers ACN-IN terminal. Tighten the terminal securely to 16 in lbf (1.8 N-m).

AC OUTPUTS WIRING

• Route the wires (hot, neutral, and ground) from the sub panel through the AC INV. Output strain relief clamp. Tighten the strain relief clamp securely on the wires. Always leave a little extra slack in the wiring.
• Connect the OUT1 wire (black) and OUT2 (red) from the Inverter/Charger to the sub panel. Tighten the terminals securely, to 16 in lbf (1.8 N-m).
• Connect the ACN-OUT Neutral out (white) from the Inverter/Charger to the sub panel. Tighten the terminal securely, to 16 in lbf (1.8 N-m).
• To prevent possible damage to the case, always add additional external non-conductive strain relief when using large diameter multi-conductor cables for AC inputs and AC outputs

NOTE: Double-check the manufacturer’s side of the terminal block. Tighten to 16 in lbf (1.8 N-m) if they come loose.

AC GROUND WIRING

• Connect the ground (Green) wire from the main panel to the AC Ground IN terminal. Tighten the terminal securely, to 16 in lbf (1.8 N-m)
• Connect the ground (Green) wire from the sub panel to the AC Ground OUT terminal. Tighten the terminal securely, to to 16 in lbf (1.8 N-m)

NOTE: The Ground terminals are lugs and they are not labelled within the compartment. See diagram on the following page.

AC WIRING CHECKS

• Ensure all wires are secured. In RV applications use zip ties or other non-conductive fasteners to prevent chaffing or damage from movement and vibration.
• Ensure strain reliefs or grommets are in place to prevent damage to the wiring or conduit where it passes through the walls/bulkheads or other openings.
• If using large diameter multi-core cable, add additional external non-conductive strain relief(s) to prevent damage to the Inverter/Charger case.
• After checking all AC connections and ensuring all the terminal set screws are tightened securely, replace the AC Cover Plate, 3 x Phillips set screws, and the covers on the main and sub panels.

AC WIRING FOR MARINE APPLICATIONS

To comply with American Boat and Yacht Council (ABYC) requirements for marine installations, all wire connections into the AC terminal blocks must be protected with stainless steel wire protectors such as pin terminals to prevent wire damage from the set screw.
