5. Attach the four, four-tab jumpers (included in the Conext XW+ Connection Kit
for INV2 INV3 PDP) to top and bottom of AC breakers as shown in Figure
3-24.
AC Wiring for a Dual-Inverter System
1. Connect the grid wiring and inverter load sub-panel wiring to the new
jumpers as shown in Figure 3-25 on page 3–45.
2. Connect INV1 LOAD (INV1 L1-LOAD, INV1 L2-LOAD), INV2 LOAD (INV2
L1-LOAD, INV2 L2-LOAD), and INV2 GRID (INV2 L1-GRID, INV2 L2-GRID)
wires to AC breakers as shown in Figure 3-25 on page 3–45.
3. Connect neutral (INV2 N-LOAD) and ground (INV2 GROUND) wiring as
shown in Figure 3-25 on page 3–45.
4. Remove the knockouts on the upper faceplate of the PDP to accommodate
additional breakers.
5. Re-label the AC breakers with the appropriate labels, included with the
Conext XW+ Power Distribution Panel.
6. Install the custom designed bypass interlock plate, as shown in Figure 3-26
on page 3–46.

Note: If a backup generator or other secondary AC source is installed in the
system, reuse two of the dual-tab jumpers previously installed on INV1 Grid/
Bypass breakers for generator breakers.

IMPORTANT: Install L1 PDB in first
Grid breaker slot facing FRONT.
Failure to do so will result in overlap
of terminals on L1 and L2 PDBs and
potential for shorting to occur.
