The display should indicate STARTING… Vout=xxx.xVac Iout=x.xxAac Pressonce to see Master Ad. I Stand Alone followed by T.Switch Online Load->Inverter S Press or until the display shows Vgrid=xxx.xVac Igrid=x.xxAac Press or until the display shows The Vout and Vgrid should be close to 120Vac. If the Vgrid and Vout are also not within 20% of each other, contact Datapath FSR and have them check the inverters and generator. Step 1 Step 2 Step 3 Step 4 followed by the screen below. If the Ku Trailer is running and the Inverter is already turned on, you can proceed to Step 2 without performing Step 1. If this screen shows “Load -> Grid” then continue with the steps to verify the other settings. The screen will return to the Vgrid or Vout screen in a few seconds on its own.

7. Follow these instructions for both Left and Right inverters on the Ku Trailer. When you change from Mode 1 to Mode 2, you may notice a system outage. This may be a minor outage with no downtime or it may require the HPA to go into delay-T status for a few minutes (usually no longer than 2 minutes) and should come back up on its own. Maintain visibility of the system until it comes back up. If it does not, ensure everything is still turned on and has not tripped a circuit breaker. If the Ku trailer is not currently in operation, power everything up with the onboard generator and, once powered up, perform the steps above.. You must ensure that DC power is applied to the inverters by turning on the DC inverter power switch on the Right side stack. You must also ensure that the Battery Charger on the Right Side stack is turned on as well in order to maintain a charge on the batteries for backup purposes.
