Conext XW+ Inverter/Charger Grounding
The Conext XW+ is provided with ground terminals that must be reliably
connected to ground (protective earth) by appropriately sized equipment
grounding conductors. System grounding for the AC and DC systems must be
done according to all applicable NEC and local installation codes.
For more information about system grounding, see “Grounding the DC System”
on page 3–8 and “AC Equipment Grounding” on page 3–20.
Dual Inverter/Charger Installation
This section provides instructions for adding a second Conext XW+ to your
installation. Complete the following installation steps only after you have already
connected the PDP to the first Conext XW+, as shown in “Wiring the Conext XW+
Inverter/Charger with a PDP” on page 3–7.
DC Grounding
See “Grounding the DC System” on page 3–8.
DC positive bus bar installation
1. Remove the existing bus bar from the bottom terminal of the GJ250A 160
VDC, 3/8" DC disconnect/breaker (pre-installed in the PDP).
2. Install a second GJ250A - DC rated breaker (included with the Conext XW+
Connection Kit for INV2 INV3 PDP) next to the existing DC disconnect/
breaker.
3. Install the DC positive bus bar included with the Conext XW+ Connection Kit
for INV2 INV3 PDP. (This DC positive bus bar supports up to three GJ250A -
DC rated breakers.)
4. Remove the appropriate knockout from the Conext XW+ Power Distribution
Panel lower faceplate.
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 or serious injury.
Note: Replace faceplates after all AC and DC wiring is complete.
