OPERATION
1.
Connect the load to the inverter. If multiple loads are used it is good practice to switch all
loads off before switching on the inverter. This will prevent multiple in-rush currents from
tripping protective circuits in the inverter.
2.
Switch on the inverter. At this point, the sound of the cooling fans should be evident.
3.
The appropriate front panel LEDs should be illuminated.
4.
To test the inverter, use a True RMS type meter to confirm the output voltage is as
specified.
5.
Units provided with the A1 bypass option are AC preferred. This means that the incoming
AC line voltage will be routed to the inverter output terminals (or outlets) whenever it is
present. During this time the inverter is in a standby condition. If the AC input is removed
the output terminals will be switched to the inverter and operation from the DC source
begins.
