Testing the Inverter
Before proceeding,
fi
rst test whether the inverter was successfully installed.
Use the functional test below to test the inverter, and then perform the GFCI
test that follows to ensure the protection device is functioning properly.
2.5.1 Inverter Functional Test
After all electrical connections to the inverter and batteries have been
completed, plug a small AC load (e.g., 40W light bulb or small appliance)
into the GFCI’s outlet, and follow these steps to test the installation and the
inverter’s operation.
CSW412 Inverters:
1. Toggle the ON/OFF Power Switch to the ON (I) position to turn the unit
on.
2. The Power Indicator will turn on to indicate that the AC output power is
available.
3. Check that the AC load is on (i.e., the bulb lights).
Note:
If the bulb does not light, the GFCI may have tripped. Reset the GFCI
by pressing the RESET button
.
CSW1012 and CSW2012 Inverters:
1. Press and hold the Power/Select button until a beep sound is heard
(about 1 second). The Status light turns on.
2. Check that the digital display alternately shows the inverter’s measured
battery voltage and output power.
3. Check that the AC load is on (i.e., the bulb lights).
Note:
If the bulb does not light, the GFCI may have tripped. Reset the GFCI
by pressing the RESET button
.
If the inverter passes all steps, it is functioning properly and ready for use.
If the inverter fails any of the steps, refer to the troubleshooting information
in Section 4.0.
2.5.2 GFCI Function Test
Use the steps below to periodically test the GFCI to ensure it is functioning
properly.
1. Turn the inverter on.
2. Plug a small AC load (e.g., 40W light bulb) into the GFCI’s outlet.
3. Check that the AC load is on (i.e., the bulb lights).
4. Press the GFCI’s TEST button. The GFCI’s RESET button should pop out,
and the power should shut off (light bulb goes out).
Note:
If the bulb remains lit or the RESET button does not pop out, the GFCI
may not be functioning properly
.
5. Press the RESET button. The AC load should come back on (the bulb
lights again).
