5.02 If the inverter fails to operate, use the
following troubleshooting procedure.
5.02.1 Connect a 100 watt light bulb to the
inverter output.
5.02.2 Make sure the inverter is turned
"On", the output circuit breaker is reset and that
the voltage is at least +12-volt at the DC input
terminals. If not, check DC wiring connections and
the line fuse.
5.02.3 Check the connection to the remote
switch, if used. +12VDC (-12VDC if option "R2")
must be present at the violet wire for the unit to
operate. If not, check any fuses in the +12 VDC
(-12VDC if option "R2") remote switch circuit.
5.02.4 Observe the fault indicating lights on
the front of the inverter.
a) The Low input voltage light indicates a
low battery condition. Switch the inverter “Off” for
5 seconds, then “On” again. The light coming on
again indicates a fault in the battery wiring, bat-
tery capacity and voltage or the fuse.
b) The Overload light indicates an output
wiring short circuit or a load that is too large for the
power rating of the inverter. Switch the inverter
“Off”, remove the short circuit or excessive load
from the output, then switch the inverter back
“On”.
c) The High temperature light indicates the
inverter has overheated. The unit will automatically
turn back on when it has cooled to 40
0
C. Verify that
the inverter is not in a closed compartment and that
the fan is not blocked.
5.03 If the battery charger fails to operate,
follow this troubleshooting procedure:
5.03.1 Verify that there is 120VAC power
to the unit. If not, check all external power wiring
and external circuit breakers or fuses.
5.03.2 Verify that there is DC voltage by
measuring the voltage at the DC input terminals
and then turning the voltage adjustment higher
and reading the higher voltage at the terminals.
5.04.1 If the above steps are completed
and the inverter still will not operate satisfactorilly
call Airpax Dimensions, Inc. for a return material
authorization number.
