Preparing the Cables

24
Connect and disconnect DC wiring only after opening the disconnect switches or
breakers at all AC and DC sources.
For the best load starting surge performance, the DC cables should be as short as
possible and large enough to handle the required current, in accordance with the
electrical codes or regulations applicable to your installation. Avoid excessive
cable lengths. The DC cables must be copper and must be rated 90 °C
minimum.
For recommended DC cables and fuse size, see Table 2, "Required DC Input
Cable (copper) and Fuse Size" on page 11. Using a longer or smaller gauge cable
may cause the inverter to shut down under heavy load.
To prepare the DC cables:
1. Cut the negative cable to the required length. Strip off enough insulation so
you can install the terminals you will be using.
Xantrex recommends the use of crimp connectors. The connector should be
designed for a 3/8" stud size to connect to the RS2000. If a crimp connector is
used, it should be crimped using the tool indicated by the connector
manufacturer.
2. Cut the positive cable to the required length. Strip off enough insulation so
you can install the terminals you will be using.
3. Attach the connectors to the ends of both cables. Make sure no stray wire
strands protrude from the connectors.
