Connecting the DC Cables

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.

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 1800 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.

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.

.

WARNING: Explosion or fire

Do not complete the next step if flammable fumes are present. Explosion or fire may result if the disconnect/battery selector switch is not in the off position. Thoroughly ventilate the battery compartment before making this connection.

13.Connect the cable from the negative post of the battery to the negative DC terminal of the inverter.
