WARNING
ELECTRICAL SHOCK HAZARD
Use a torque screwdriver to tighten the captive nut panel screw to
5 in-lb torque of force to ensure a proper ground connection and a
required tool access to the wiring compartment.
Failure to follow these instructions can result in death, serious
injury, or equipment damage
.
DC Grounding
To connect the DC ground:
1. The equipment grounding lug (DC ground lug) on the DC end
of the Freedom X is used to connect the chassis of the
Freedom X to your system’s DC negative connection or
grounding bus point as required by electrical regulations.
2. Use copper wire that is either bare or provided with green
insulation. Do not use the DC ground lug for your AC
grounding. See the AC wiring instructions in this section.
3. Follow the guidelines below that correspond to the specific
type of installation. These guidelines assume you are using
the DC supply cable and fuse sizes recommended in this
guide. If you are using different sizes, refer to the applicable
installation code for DC grounding details.
4. See
for the location of the DC ground lug. Make
sure to tighten the bolt on the DC ground lug to a torque of
23 in-lb (2.6 N-m) of force. Apply an anti-corrosion
compound to the copper wire prior to connecting to the DC
ground lug.
Recreational Vehicle
Use 8AWG minimum-sized, stranded copper wire and connect it
between the Chassis Ground lug and the vehicle’s DC grounding
point (usually the vehicle chassis or a dedicated DC ground bus).
See regulatory references below.
Marine
Use copper wire that is bare or has insulation rated minimum
105 °C, and connect it between the Chassis Ground lug and the
boat’s DC grounding bus or engine negative bus. For the Freedom
X 1000 120VAC 12VDC and Freedom X 2000 120VAC 24VDC,
use a wire of gauge 3AWG minimum. For the Freedom X 2000
120VAC 12VDC, use a wire of gauge 1/0AWG minimum. For the
Freedom X 3000 120VAC 12VDC, use a wire of gauge 1/0AWG
minimum. See regulatory references below.
Regulatory
references
For DC voltage systems under 50 VDC in an RV installation, an 8AWG copper
bonding conductor would be acceptable for the inverter enclosure ground bonding
only per UL458 §63.6; §30.10 standard [≤ 150 mV @ 30A connection, per §63.9;
§63.10] and per ANSI/RVIA LV code §2-5.1 Bonding Voltage Converter
Enclosures. The "house" battery system must, however, be ground bonded per
ANSI/RVIA LV code §2-4 Auxiliary Battery Grounding; and
For DC voltage systems under 50 VDC in a marine installation, [UL458 §SA7.2]
a DC Grounding conductor shall not be smaller than one size under that required
for current carrying conductors supplying the device per ABYC E-11 §11.16.2 but
not less than 8AWG [USGC 46 CFR §111.05-31].
