Wiring the Conext XW+ Inverter/Charger with a PDP
975-0239-01-01 Rev J 3–27
This manual is for use by qualified personnel only
An inverter load sub-panel and AC conduit must be installed before your Conext
XW+ installation can be completed.
Wiring 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
(9.27mm) cable (maximum).
See “Torque Values” on page 2–16 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+ Inverter/Charger 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.
To connect the Conext XW+ 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).
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 damage to equipment.
