If the test fails at any point, go to “Step 6: Performing Checks Prior to Initial Start-
Up” on page 1–29 and go through the checklist again to check the installation.
Then perform the test again. If the test fails again, see the troubleshooting
section in the Conext SW Inverter/Charger Owner’s Guide.
Testing in Invert Mode
To test the Conext SW in invert mode, using a 100 watt light bulb as the test
load:
1. Close the DC disconnect switch or the DC circuit breaker to supply DC
power to the Conext SW.
Wait for the LEDs on the front panel to flash on and off, indicating that the unit
is successfully initializing (10 to 30 seconds). The LEDs will turn off after
initialization.
If none of the LEDs come on or flash intermittently, make sure the voltage at
the DC terminals on the Conext SW is correct, as described in “Step 6:
Performing Checks Prior to Initial Start-Up” on page 1–29.
2. After initialization, observe that none of the lights on the front panel should
remain illuminated.
3. Press the Inv Enable button. Verify that the green Inv Enabled LED
illuminates.
4. Connect the Conext SW to the test load by closing the AC breaker that
controls the circuit that the test load is connected to.
If the light bulb illuminates, the Invert mode is working.
5. Press the Inv Enable button to disable inverter mode. The Inv Enabled LED
goes off.
Testing in Charge Mode and AC Bypass Mode
1. Start the AC generator, if off-grid. If grid-connected proceed to step #2.
2. Close the main breaker in the AC input panel (the AC input panel feeds
power from either the generator or grid) in order to supply AC power to the
unit.
Verifying charging: 3. After a few seconds, verify that the AC IN / Charging LED on the front panel is
turned on and that it starts flashing indicating that the batteries are being
charged.
Verifying AC
bypass:
4. Disable the AC source by opening the main breaker in the AC input panel
and turn off inverter mode by pressing the Inv Enable button.
5. Connect the test load to the AC output connection of the unit.
6. Enable the AC source by closing main breaker in the AC input panel and the
test load should turn on after ten seconds.
