Connecting the DC Cables to the Inverter/Charger
FIRE HAZARD
Use only appropriately sized copper cable. Loose connections, improper
connections, and under-rated cables will overheat. Make sure that the
supplied bolts on the inverter/charger are tightened to a torque of 14.9–
16.3 Nm. Torque all other connections to the manufacturer's
specifications. Make sure the DC cable, washers, and bolt are assembled
in the order shown in Figure 7.
Failure to follow these instructions can result in death or serious injury.
EQUIPMENT DAMAGE DUE TO REVERSE POLARITY
Before making the final DC connection or closing the DC breaker or
disconnect, check cable polarity at both the battery and the inverter/
charger. Positive (+) must be connected to positive (+). Negative (–) must
be connected to negative (–).
Failure to follow these instructions can damage the unit and/or damage
other equipment.

To connect the DC cables:
1. Route the DC cables from the battery bank to the inverter/
charger. Observe the "Guidelines for Routing the DC
Cables" on page 30.
2. Install a DC fuse and disconnect switch or a DC circuit
breaker between the inverter/charger and the battery. It
must be installed in the positive side of the DC circuit, as
close as possible to the battery.
This protects your battery and wiring in case of accidental
shorting. See Table 3 on page 15 for required fuse or
breaker size.
3. Open the DC disconnect switch or turn off the DC circuit
breaker.
4. Connect one connector on the POSITIVE (+) cable to the
POSITIVE DC terminal on the inverter/charger, as shown
in Figure 7. The connector goes on first, then the lock
washer and bolt.
