SINUS/SINE INVERTER – SI-/TSI-SERIES
Possible reason
No input voltage.
blown fuse due to polarity
reversal
(Caution: polarity re-
versal can damage the
inverter despite a fuse)
1. connection to
consumers cut off
2. short circuit of
consumers
possible undervoltage
(see table)
]
Solution
1. check battery voltage
2. check input fuse
3. check all connections to
battery
Exchange blown fuses and
connect cables correctly.
If inverter does not work
after exchange, it's broken.
Please call the support!
1. check connection
2. check if short circuit
1. check charging status
of battery, charge if
necessary
2. check compatibility
of battery cable, use
higher cross section if
necessary
3. check if conductive
parts (cables, pole termi-
nals, lugs) are damaged
