Conditions
Switch (a, fig 7.1 or 7.2), wait for 3 minutes and switch on again.
note: If the unit goes into overload once again, remove all the loads, reset as above
and switch on. If it goes into overload condition again without any load, it is defective.
Please call Technical Support.
SYMPtoM
on switching on, the input voltage lEd bar graph (d, fig. 7.1 or 7.2) does not light.
There is no Ac voltage.
PoSSiBle cAUSe #1
There is no voltage at the dc input terminals
Remedy:
1. check the continuity of the battery input circuit.
2. check that the external battery fuse is intact. replace if blown
3. check that all connections in the battery input circuit are tight
PoSSiBle cAUSe #2
Input voltage of > 10.5V is available at the dc input terminals
Polarity of the dc input voltage has been reversed that has blown the
internal dc side fuses.
Remedy:
correct the polarity of the input connections and replace the internal fuses
(note: reverse polarity may cause permanent damage). If the unit does not work
after replacing the fuses, the unit has been permanently damaged.
call Technical Support.
SYMPtoM
Ac output output voltage reads low (96 to 104 VAc) when measured with an
ordinary voltmeter.
PoSSiBle cAUSe
The voltmeter being used is not designed to read the true rMS value of modified
sine waveform.
Remedy:
use true rMS reading voltmeter like fluke 87.
