Conext XW Pro Installation Guide

Wiring for connections between the PDP and the inverter load sub-panel is not included.

Power distribution jumpers in the PDP accept up to a #2/0 AWG (9.27 mm

) cable

(maximum).

See "Torque Values" on page40 for torque requirements.

To install the inverter load sub-panel and AC conduit:

1. Choose a location for the inverter load sub-panel and install it according to the

manufacturer’s directions.

2. Install an AC conduit between the PDP and the inverter load sub-panel.

3. Determine which circuits the Conext XW Pro will power and install the appropriate

circuit breakers into the inverter load sub-panel.

4. For on-grid systems:

a. Disconnect all power to the main AC panel (utility grid).

b. Choose which circuits will be backed by the inverter(s), and remove their

wires from the main panel.

c. Reroute these wires to the new inverter load sub-panel.

5. Remove unused breakers from utility panel.

6. Install a 60amp maximum (disconnect) main circuit breaker in the inverter load sub-

panel.

NOTICE

BACK FED AC POWER

Back fed AC Power can damage equipment. Do not wire the inverter’s AC output port

directly to the utility line or generator output.

Failure to follow these instructions can result in equipment damage.

To connect the Power Distribution Panel (PDP) to the Inverter Load Sub-Panel

and Utility Grid:

1. Connect L1 (from the L1 output jumper) and L2 (from the L2 output jumper), Neutral,

and Ground to your inverter load sub-panel.

2. Connect the ground wire between the PDP and the main AC Panel (utility grid).

3. Connect Neutral from the PDP to the main AC panel (utility grid).

4. Connect L1 and L2 from the input side of the 60 A, 120/240 VAC, two-pole, Type

QOU AC1 breaker (L1 and L2 jumpers) to the main AC panel (utility grid).
