4. Install a fuse and disconnect switch or breaker between the inverter and
the battery. Ensure that the disconnect switch or breaker is open (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.
5. Place one of the provided DC terminal covers over the terminal.
Ensure that no part of the terminal cover goes in between the battery
cable lug and the input terminal surface.
6. Attach the positive cable to the inverter positive DC terminal, and then
attach the other connector to the POSITIVE (+) terminal on the fuse or
breaker at the battery.
WARNING: Fire and energy hazards
If left exposed and unprotected, there is a risk the terminals could be short
circuited by a tool, lug, jewelry, or other metal item, which could present a risk of
burns or fire hazard. Use the provided terminal covers to prevent shorting
between the cable lugs or from the cable lugs to the inverter chassis. Make sure
that no part of the cover is between the battery cable lug and the surface of the
input terminal.
CAUTION: Reverse polarity
DC power connections to the inverter 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. Damage caused by a reverse polarity connection is not covered by
warranty.
CAUTION: Wire terminal damage
Do not over-tighten the nut on the DC input terminals. Damage to the wire and
DC input terminals may result.
WARNING: Fire hazard and risk of wire and
equipment damage
Loose connections cause excessive voltage drop and may cause overheated wires
and melted insulation.
