Checking Battery Status
You can check the battery status by pressing the Select button until the
Input Voltage LED illuminates. The battery voltage appears in the three-
digit LED display. The normal operating battery voltage range is between
11 and 15 volts.
Checking Output Power
You can check how much power the XM 1800 is supplying to the
connected loads by pressing the Select button until the Output Power
LED illuminates.
Operating Several Loads at Once
If you are going to operate several loads from the XM 1800, turn them on
one at a time after you have turned the inverter on.
Turning loads on separately helps to ensure that the inverter does not have
to deliver the starting current for all the loads at once, and will help
prevent an overload shutdown.
Turning the Inverter Off When Not Used
The XM 1800, on average, draws less than 0.5 A (XM 1000) or 0.7 A
(XM 1800) from the battery when the inverter is on with no load
connected. However, when it is left in this state the XM 1800 will
eventually discharge the battery.
To prevent unnecessary battery discharge, turn the XM 1800 off when
you are not using it.
