2.0 Installation

5. Check the output voltage of the inverter by connecting a true

RMS multimeter to the outlets powered by the inverter. Verify the
voltage is 230 VAC +/- 5 VAC. If not using a true RMS meter the
output AC voltage could indicate from 170-250 VAC, depending
on the battery voltage.

6. Turn on or connect a load to the outlets and verify it comes on.

Continue to keep the load connected and turned on.

7. Press the remote ON/OFF switch to turn the inverter off. If the

remote is not used, press and release the inverter’s ON/OFF power
switch to turn the inverter off. The inverter’s status indicator and
the connected load should go off.

8. Apply AC power to the inverter’s AC input. After the AC input

power is qualiﬁ ed (approximately 15 seconds), the incoming
AC power will transfer through the inverter to the inverter’s AC
output and power the connected load. Verify that the inverter’s
status indicator and the connected load come on.

9. Even though the connected load is on, the inverter is currently

disabled/off. Press the remote’s ON/OFF switch (or press and
release the ON/OFF power switch on the inverter) to enable/
turn on the inverter.

10. Disconnect the incoming AC power to the inverter. Verify the

connected load remains on, but now is powered by the inverter.

If the inverter passes all the previous steps, the inverter is ready
for use.

If the inverter fails any of the steps, refer to the Troubleshooting
section.
