Connecting the DC Chassis Ground (Earth)
The Truecharge™ 2 Battery Charger Battery Charger must be
connected to a grounded, metal, permanent wiring system, or
an equipment-grounding conductor should be run with the
circuit conductors and connected to the equipment-grounding
lead on the charger. Connections to the battery charger must
comply with all local and application-specific codes and
ordinances.
Xantrex recommends that you install a DC chassis ground
(earth) wire from the ground stud on the Truecharge™ 2
Battery Charger to the engine bus or DC ground bus. The DC
chassis ground (earth) wire should be sized correctly with the
power conductors, and both must be sized for the battery
fuses that are used to protect the DC wiring. Refer to your
local electrical codes to verify the requirements in your
jurisdiction for your application.
To connect the DC chassis ground (earth):
1. Locate the ground stud on the Truecharge™ 2 Battery
Charger.
2. Connect the DC chassis ground (earth) from the ground
stud to the ground bus. See Figure 2-1, “Typical
Truecharge™ 2 Battery Charger System Installation” on
page 2–3.
Use a flat washer, a lock washer and a nut (included in
the installation kit) to secure the connection.
3. Tighten the nuts to 2.3 N-m (20 lb-in.) torque and test
that the wire is secure. Do not over-tighten as this may
result in damage to the charger.
WARNING: Electric shock hazard
Have an electrician install a properly grounded circuit if one is not
available. Improper connection can result in risk of electric shock.
