Inverter Operation Using the Front Panel
Once the inverter/charger is installed, you can operate it in invert mode. The
steps below will test the unit for normal operation using the front panel.
To test the inverter using the front panel:
1. Press the Inv Enable button on the Conext SW on the front panel. The
Inv Enabled LED illuminates.
2. Turn on the main AC breaker or AC disconnect to supply AC input power to
the inverter.
3. Turn off the main AC breaker or AC disconnect to stop AC input power from
going into the inverter.
4. Place a load on the inverter. This also usually means turning on the inverter’s
AC distribution sub-panel’s breaker switch.
5. Connect a load such as a lamp into an outlet connected to the sub-panel
circuit and turn it on. The lamp lights up.
6. Repeat step #2. The lamp will remain lit up.
7. Repeat step #3. The inverter/charger should invert immediately. The transfer
relay will make a clicking sound and the Inv Enabled LED will illuminate.
The lamp should remain lit up. If any part of this test does not happen
correctly, determine the cause before continuing to use the unit.
8. Monitor the Conext SW front panel.
The indicator LEDs on the front panel show you the operating status of the
Conext SW. A description of the LEDs is provided in Table 3-1.
If none of the front panel LEDs are on, see “General Troubleshooting
Guidelines” on page 5–2.
IMPORTANT: Review the “Important Safety Instructions” on page v before
operating the inverter/charger.
NOTE: The Inv Enabled LED will remain lit. However, AC will continue to be
passed through (also called AC bypass) to the loads until conditions exist that
cause AC to be disqualified, in which case the unit will start inverting. The AC
IN LED should also illuminate. The Charging LED will start flashing to
indicate that the unit is charging the battery. The charger automatically starts
when qualified AC power is connected and when the battery is not fully
charged.
