DC Connections
BEFORE MAKING ANY CONNECTIONS, MAKE THE POWER SWITCH IS OFF.
DC INPUT CONNECTION
Before making any connections to the unit, you will need to prepare an external circuit breaker
or fuse for the DC power source. See
Specifications
for the appropriate rating.
This unit is equipped with a Marathon Terminal Block connector with 4 1⁄4” studs to serve
as a DC input connection. An externally-supplied circuit breaker or fuse is required for safe
operation.
• Connect the positive terminal of the DC power source to the indicated terminal block
stud(s) using RED AWG12 stranded wire and appropriately sized lugs.
• Connect the negative terminal of the DC power source to the indicated terminal block
stud(s) using BLACK AWG12 stranded wire and appropriately sized lugs.
TIP:
Use the largest gauge (AWG 1/0) recommended) and shortest length of welding
wire possible.
The biggest effect on Inverter performance and EMI is the length and gauge of the DC Input
connections.
TIP
:
Make sure the wire insulation butts up tightly against the lug.
For maximum safety, no non-insulated wire should be exposed. Trim the length of
non-insulated wire if necessary.
CAUTION
:
Do not reverse connect the input wires.
This will cause serious damage to the Inverter and will not be covered under warranty.
