5. Start-up and Test

Connecting the Batteries to the Inverter

After all electrical connections have been completed, connect the batteries to the
inverter to begin the start-up process.
CAUTION: Verify correct battery voltage and polarity before connecting the cables to the inverter.
Replace the fuse or (close the breaker) at the DC disconnect.
Remove the electrical tape from the cable lugs and verify 12 VDC at the cable
connectors using a multimeter. Verify correct polarity: Black is negative (- ); Red is
positive (+).
Connect the negative (BLACK) battery cable to the inverter's negative terminal. The
cable lug must be flush to the terminal's surface. Place a lock washer and nut over the lug and torque the
connection to 10 to 15 foot pounds.
NOTE: There may be a spark (and audible snap) when the cable lug first contacts the inverter's positive
terminal. Th is is a normal condition.
Connect the positive (RED) battery cable to the inverter's positive terminal. The cable
lug must be flush to the terminal's surface. Place a lock washer and nut over the lug and torque the
connection to 10 to 15 foot pounds.
Verify all cables and connectors are properly secured.
Place the red and black terminal covers on the inverter's DC connector. Secure the covers with
enclosed hardware.
If the batteries are in an enclosure, perform a final check of the hold down brackets and all connections.
Close and secure the battery enclosure.

Final Inspection and Power-up

Prior to starting the inverter, make sure all connected appliances are switched
OFF or disconnected from the AC receptacles.
Use a multimeter to verify 12 VDC at the inverter's DC connectors.
Switch the inverter power switch to ON. The inverter's LED will flash indicating
DC power and the start -up sequence.
NOTE: When using the remote control, the inverter's ON/OFF switch is disabled in
Charge mode.
V e r i f y t h e b r e a k e rs on the distribution panel are switched ON.
Use a true RMS multimeter to verify 120 VAC at the coach's AC outlets. Connect the inverter to shore
power and switch the main circuit breaker ON. Verify the inverter's LED switches from
INVERTER to AC IN (SHORE POWER). Use a true RMS multimeter to verify 120 VAC at each
of the coach's AC outlets. Switch the Shore Power OFF. Verify the inverter's LED switches
to inverter mode.
