Breaker installation
Wiring a second Conext XW+ requires the installation of additional 60 A, 120/240
VAC, two-pole, type QOU AC breakers (included with the Conext 120/240VAC
Breaker Kit).
To install breakers for a dual-inverter system:
1. In the PDP, disconnect all AC wires (from the utility grid or generator and to
the inverter load sub-panel) and remove the pre-installed two-tab power
distribution jumpers connected to the top and bottom terminals on the AC
breakers.
2. Remove bypass interlock bracket.
3. Disconnect INV1 AC LOAD (INV1 L1-LOAD, INV1 L2-LOAD) wires from the
top terminals on right-hand side breaker.
4. Install the dual-pole AC breakers (included with the Conext 120/240VAC
Breaker Kit) onto the DIN rail, next to the pre-installed dual-pole AC breakers
in the PDP.
WARNING
UNGROUNDED EQUIPMENT
Equipment ground terminals must be reliably connected to ground by
appropriately sized grounding conductors. All installations must comply with
national and local codes. Consult local and national codes for specific
grounding and bonding requirements.
Failure to follow these instructions can result in death or serious injury.
Note: Ensure that the neutral (INV1 N-LOAD) wiring remains connected, as
shown in “AC wiring the Conext XW+ PDP to the Conext XW+ Inverter/Charger”
on page 3–22.
