Basic Installation Procedures
To make the DC connections:
1. Make sure the inverter/charger is off and no AC or DC is
connected to the unit.
2. Remove the wiring compartment cover by loosening the
captive nut panel screw.
ELECTRIC SHOCK HAZARD
Use a screwdriver to loosen the captive nut panel screw.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
3. Loosen the DC terminal nuts from the terminal bolts and set
them aside for later.
4. Strip ½" (13 mm) to ¾" (19 mm) insulation from one end of
each cable. The amount stripped off will depend on the
terminals chosen.
5. Attach the connectors that will secure the cables to the
battery, to the disconnect/battery selector switch, and the
fuse block. The connectors you use must create a
permanent, low-resistance connection. It is recommended
to use approved and certified cable ring lugs. Use the tool
recommended by the terminal manufacturer. Make sure no
stray wires protrude from the lug or terminal.
NOTE: You may find it more convenient to have the cable
lugs attached by the company that sells you the cable and/or
connectors.

WARNING
6. Strip ½" (13 mm) to ¾" (19 mm) of insulation from each
cable end that will be connected to the inverter/charger
cable. The amount stripped off will depend on the terminals
chosen.
7. Attach the cable ring lug that will join the cable to the
inverter/charger DC terminal. Cover the lug stem with heat
shrink insulation (see Step 6: Connecting the DC Cables) to
ensure that the lug does not touch the enclosure.
8. Install a fuse and fuse holder in the cable that will be used for
the positive side of the DC circuit. The fuse must:
a. be as close to the battery positive terminal as possible
b. be rated for DC circuits
c. have an Ampere Interrupting Capacity (AIC) that
exceeds the short-circuit current available from the
battery (that is, Class T fuse)
9. To prevent sparking when making the connection, ensure
the disconnect/battery selector switch is off.
10. Route the positive cable through the left side strain relief
clamp and attach the cable lug on the positive cable to the
positive DC terminal on the inverter/charger.
11. Fasten the DC terminal nut (set aside earlier) to the terminal
bolt. Tighten the nut to a torque of 8–9 N-m (71–80 in-lb ) of
force. Do not overtighten. Make the connection snug enough
so the cable lug does not move around on the DC terminal.
Center it through the DC knockout hole and do not let it
touch the edge. See Step 6: Connecting the DC Cables on
page 27.
