Installation

9. Install the lock washer and nut that are supplied with the inverter.
Tighten the nut to a torque of 6.3–6.6 foot pounds (8.5–9.0 Nm). Make
the connection snug enough so the ring terminal does not move around
on the DC terminal, but do not overtighten. See
Figure 3-3 on page 3–17
DC Panel Connections.
10. Before proceeding, double check that the cable you have just installed
connects the positive DC terminal of the inverter to the fuse holder, and
that the other end of the fuse holder is connected to the positive terminal
on the battery.
CAUTION
Loose connections cause excessive voltage drop and may cause
overheated wires and melted insulation.
CAUTION
Do not over tighten the nut on the DC input terminals. Damage
to the DC input terminals may result.
The maximum torque setting is 6.3–6.6 foot pounds (8.5–9.0
Nm).
CAUTION: Reverse Polarity
DC power connections to the XPower Plus must be positive to
positive and negative to negative.
A reverse polarity connection (positive to negative) will blow a
fuse in the inverter and may permanently damage the inverter.
The fuse is not user replaceable and the inverter may need to be
returned for servicing.
Damage caused by a reverse polarity connection is not covered
by your warranty.
