of the inverter to the positive terminal of the
battery's main fuse, or to the battery selector
switch, if you are using one. Make a secure
connection.
You might observe a spark when you make this
connection since current can flow to charge
capacitors in the inverter.
Operation.
Turn the inverter On by using the ON/OFF switch
on the left side panel .
The inverter is now ready to deliver AC power to
your loads. If several loads are to be operated by
the inverter, turn them on separately, after the
inverter has been turned On. This will ensure that
the inverter does not have to deliver the starting
currents required for all the loads at once.
