Consult Configuration for Normal Loads and Configuration for
Heavy Loads on page 13 for additional details that are specific to
your installation.
To make the DC connections:
1. Cut the cables to the correct length with enough insulation
stripped off so you can properly install the type of terminals
you will be using.
The terminals on the DC end are designed to fit up to 500
MCM crimp-on ring terminals (either AMP or ILSCO) or box
connectors.
2. Attach the connectors to both cables.
If using compression lugs, attach the terminals to both
cables using the crimp tool recommended by the
manufacturer of the ring terminals. There must be no stray
wire strands protruding from the terminal. If using box lugs,

switch or breaker is turned off before installing. They 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 Installing the
Inverter on page 21.
5. Attach one connector on the positive cable to the positive
DC terminal on the DC end, and then attach the other
connector to the positive (+) terminal on the fuse or breaker.
