AC wiring the Conext XW+ PDP to the Conext XW+ Inverter/Charger
To connect the Conext XW+ Power Distribution Panel to the Conext XW+
Inverter/Charger:
1. In the Conext XW+ Power Distribution Panel (PDP), locate the wire labelled
INV1 N-LOAD (SPLIT PHASE), pre-installed in the neutral bus bar N-LOAD
terminal. Connect the INV1 N-LOAD (SPLIT PHASE) wire to the AC Load
terminal (N-LOAD) on the Conext XW+ Inverter/Charger, as shown in Figure
3-12 on page 3–23.
2. Locate the wires labelled INV1 L1-LOAD and INV1 L2-LOAD, pre-installed in
the terminals at the input (top) side of the 60 A, 120/240 VAC, two-pole, type
QOU output AC breaker in the PDP. Connect the INV1 L1-LOAD and INV1
L2-LOAD wires to the AC Load terminals (L1 -LOAD and L2-LOAD,
respectively) on the Conext XW+ Inverter/Charger.
3. Locate the wires labelled INV1 L1-GRID and INV1 L2-GRID, pre-installed in
the terminals at the bottom of the output breaker in the PDP.
4. Connect the INV1 L1-GRID and INV1 L2-GRID to the Conext XW+ Inverter/
Charger, using one of the following methods (depending on your
installation):
• If the AC source will be the utility grid, connect to the GRID (AC1) terminals
(L1-GRID, L2-GRID) on the Conext XW+ Inverter/Charger. (See Figure 3-12
on page 3–23.)
• If the system will be off-grid and the only AC source will be a generator,
connect these wires to the GEN (AC2) terminals (L1-GEN, L2-GEN) on the
Conext XW+ Inverter/Charger. (See Figure 3-14 on page 3–25.)
Note: In an on-grid system with a generator, you will need to install an additional
60 A, 120/240 VAC, two-pole, type QOU AC breaker onto the DIN rail. For
information, see Figure 3-13 on page 3–24.
Note: Both lines (L1 and L2) of input power must be connected in order for the
Conext XW+ Inverter/Charger to operate. For example, L1 and L2 of Grid Input
L1 and L2 of Gen Input need to be connected.
Note: Additional neutral terminals (N-GRID, N-GEN) are provided on the Conext
XW+ Inverter/Charger for installations that do not use the XW+ Power Distribution
Panel. For more information, see “Wiring the Conext XW+ Inverter/Charger
without a PDP” on page 3–64.
