This guide for use by qualified personnel only

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 1–30.

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.

Installation Complete

Your installation is now complete. The inverter/charger is ready for use.

The preceding tests use a light test load (a light bulb) as a test case. If you

encounter problems when using a load over 1000 watts (for example, a hair dryer

or microwave), see the troubleshooting information in the Conext SW Inverter/

Charger Owner’s Guide.
