Part 1: System Startup Check
To test the charging and inverting functions:
1. Close the battery disconnect and turn on the PROsine’s ON/OFF/REM
switch.
2. To test the inverter, set the INVERTER switch to ENABLE and disconnect
the AC input source breaker.
3. Place a load on the inverter (e.g. plug a light into an outlet that the inverter is
powering) and make sure it works. The INVERTING LED should come on
and the inverter should run the load using battery power.
4. To test the charger, connect the AC input source breaker. Set the display’s
CHARGER switch to ENABLE. After a short delay, the CHARGING LED
should come on. Any AC loads powered by the inverter will also work at this
time.
5. Remove the AC shorepower. The PROsine should transfer to Inverter mode
immediately. (The transfer relay will make a clicking sound and the
INVERTING
LED will come on.) Loads should continue to operate
uninterrupted.
If any part of this procedure fails, determine the cause before using the PROsine.
Consult the Chapter 6, “Troubleshooting”.
WARNING
Review the “Important Safety Instructions” on page vii before operating the PROsine.
