Wiring the Conext XW+ Inverter/Charger and Conext XW+ Power Distribution Panel
3–8 975-0239-01-01 Rev G
This manual is for use by qualified personnel only
This section provides instructions for making AC and DC connections between
the Conext XW+ Inverter/Charger and an Conext XW+ Power Distribution Panel
(PDP), using a Conext XW+ Conduit Box and the pre-installed cables in the PDP.
To install a Conext XW+ without the Conext XW+ Conduit Box or PDP, see “Wiring
the Conext XW+ Inverter/Charger without a PDP” on page 3–67 of this Guide.
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.
Grounding the DC System
To connect the Conext XW+ to the DC grounding system, use the ground lug at
the bottom of the Conext XW+ chassis (see “Conext XW+ Features” on page 1–
4). The terminal accepts wires from #14 AWG (1.63 mm) to #2 AWG (6.54 mm).
System grounding for the DC system, which typically involves bonding
(connecting) the battery negative circuit to ground, is dependent on the system
configuration.
Note: If a Conext XW+ Conduit Box is installed, run the communication and
Battery Temperature Sensor cables through the raceway at the rear of the Conext
XW+ Conduit Box and PDP before making AC and DC connections. The
raceways become more difficult to access after AC and DC wiring is completed.
For more information, see “Communications Network Preparation” on page 2–12
of this Guide.
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: If a grounded DC system is required, ensure that the system bonding is
done in one location only, and that all conductors and connections comply with
all applicable NEC and local installation codes.
