Installing the Inverter/Charger
Connecting the DC Cables to the Inverter/Charger
FIRE HAZARD
Use only appropriately sized copper cable. Loose connections, improper connections, and
21.7Nm. 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
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 29.
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 14 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.
5.Connect the other connector to the POSITIVE (+) terminal on the fuse or breaker. Observe polarity carefully while completing the installation.
