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. This 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 brack-

ets 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.

Verify the breakers 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.
