Breaker Installation
Wiring a second and third Conext XW+ requires the installation of 60 A, 120/240
VAC, two-pole, type QOU AC breakers (included with the Conext 120/240VAC
Breaker Kits).
To install breakers for a triple-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 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. Mount the 60 A, 120/240 VAC, two-pole, type QOU AC breakers onto the DIN
rail, as shown in Figure 3-28 on page 3–49 and Figure 3-29 on page 3–50.
5. Install two jumpers, L1 and L2 at the output (bottom) terminals of the INV1,
INV2, and INV3 AC Load breakers.
6. Install two jumpers, L1 and L2 at the input (top) terminals of the INV1, INV2,
and INV3 Grid breakers. (See Figure 3-28 on page 3–49.)
7. If the installation includes a second AC source, install two jumpers, L1, and
L2 at the input (top) terminals of the INV1, INV2, and INV3 Gen breakers.
(See Figure 3-28 on page 3–49.)
AC equipment grounding
See “AC Equipment Grounding” on page 3–20.
AC Wiring for a Triple-Inverter System
1. Connect L1 and L2 AC wiring from each INV Grid breaker to the
corresponding AC Input (AC1) terminal on each of the three Conext XW+
Inverter/Chargers.
2. If the installation includes a second AC source, connect L1 and L2 AC wiring
from each INV Gen breaker to the corresponding AC Input (AC2) terminal on
each of the three Conext XW+ Inverter/Chargers.
3. Connect L1 and L2 AC wiring from each INV AC Load terminal from each of
the three inverters to the corresponding AC INV Out breaker terminal in the
PDP.
4. Connect L1 and L2 AC Load wiring to the INV Out (AC Load) jumper.
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.
Note: For illustrations of the following wiring arrangements, see Figure 3-28 on
page 3–49 and Figure 3-29 on page 3–50.
