Basic Installation Procedures
This
section for use by
qualified per
sonnel
only.
To make the DC connections
Refer to Figure 5.
1. Make sure the inverter is off and no AC or DC is connected to
the unit.
2. Remove the DC compartment cover by loosening the captive
nut panel screw.
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 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.
6. Strip ½" (13 mm) to ¾" (19 mm) of insulation from each cable
end that will be connected to the inverter cable. The amount
stripped off will depend on the terminals chosen.
7. Attach the cable lug that will join the cable to the inverter DC
terminal. Cover the lug stem with heat shrink insulation (see
Figure 5) 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:
•
be as close to the battery positive terminal as possible
• be rated for DC circuits
• 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.
11. Fasten the DC terminal nut (set aside earlier) to the terminal
bolt. Tighten the nut to a torque of 71–80 in-lbf (8–9 N-m). 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
Figure 5, “DC Cable Connections” on page 28.
