• as close to the battery as possible
• rated for DC circuits
• have an Ampere Interrupting Capacity (AIC) that exceeds the short-
circuit current available from the battery.
9. To prevent sparking when making the connection, ensure the
disconnect/battery selector switch is off.
10. Attach the connector on the positive cable to the positive DC terminal
on the inverter.
11. Install the lock washer and nut that are supplied with the inverter.
Tighten the nut to a torque of 108–120 in-lbf (12.2–13.6 N-m). 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, “DC Panel
Connections” on page 3–12.
12. Before proceeding, double check that the cable you have just installed
connects the positive DC terminal of the inverter to the disconnect/
battery selector switch, 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
120 in-lbf (13.6 N-m) .
CAUTION: Reverse polarity
DC power connections to the XM Series Inverter 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.
