Making AC Connections
This section provides instructions for making AC connections between the
Conext XW+ Inverter/Charger, the main utility panel, and your inverter load
sub-panel without a PDP.
For installations that include a PDP, see “Wiring the Conext XW+ Inverter/Charger
with a PDP” on page 3–37.
Note: AC breakers are not included with the Conext XW+ Inverter/Charger. You
will need to provide your own appropriately sized and rated AC breakers. For
more information, contact your local Schneider Electric Sales Representative.
Note: Install an inverter load sub-panel and AC conduit before completing your
Conext XW+ installation. For more information, see “AC wiring the Conext XW+
Inverter/Charger to the Inverter Load Sub-Panel” on page 3–22.
Note: Do not use a residual current detection (RCD) equipped AC source to
power either the Grid (AC1) or Generator (AC2) inputs. The AC input filters on the
Conext XW+ may cause nuisance tripping of ground fault protected outputs.
The Conext XW+ Inverter/Charger has a mains transformer which fully isolates
the battery (DC) from the Grid (AC1) and from the Generator (AC2). This galvanic
separation allows very low leakage current to pass, rendering the use of an RCD
or RCMU (residual current monitoring unit) unnecessary.
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.
Note: Wiring the inverter’s AC output to the utility or generator output will cause
severe damage to the inverter which is not covered under warranty.
