Conext XW Pro Installation Guide

AC Wiring the Power Distribution Panel (PDP) to the Conext XW Pro
To connect the Power Distribution Panel (PDP) to the Conext XW Pro:
1. In the 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
Pro, as shown in Figure 32 on page 62.
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 Pro.
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 Pro, using one of
the following methods (depending on your installation):
n If the AC source will be the utility grid, connect to the GRID (AC1) terminals (L1-
GRID, L2-GRID) on the Conext XW Pro Inverter/Charger, see Figure 32 .
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 33 on page 63.
n 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 Pro
Inverter/Charger.
Note: Both lines (L1 and L2) of input power must be connected in order for the Conext
XW Pro 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
Pro for installations that do not use the Power Distribution Panel. For more information,
see Wiring the Conext XW Pro Inverter/Charger without a PDP on page 89.
