Grounding AC Equipment
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, serious injury, or equipment
damage.
See "Grounding AC Equipment" on page59.
Installing Breakers
Wiring a second Conext XW Pro requires the installation of additional 60 A, 120/240
VAC, two-pole, type QOU AC breakers (included with the PDP 120/240V 60A 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.
Note: Ensure that the neutral (INV1 N-LOAD) wiring remains connected, as shown in
Wiring the Conext XW Pro with a PDP on page 50.
4. Install the dual-pole AC breakers (included with the PDP 120/240V 60A Breaker Kit)
onto the DIN rail, next to the pre-installed dual-pole AC breakers in the PDP.
5. Attach the four, four-tab jumpers (included in the Connection Kit for INV2 INV3 PDP)
to top and bottom of AC breakers as shown in Figure 44 .
