TV Interference
You can sometimes get interference on TV & Radio receivers. This may be improved
through use of a filter(s) but most problems occur because of Weak Signal to the TV.
On some occasions when there is interference on every station, you can try the
following:
Place the inverter farther from the TV and TV antenna and cable.
Make sure the Inverter Casing is grounded to the Vehicle Ground(Chassis)
Try to change the direction of TV signals cable and TV antenna to reduce the
interference to minimum.
Use screened antenna cable of higher quality.
SYMPTOM
POSSIBLE CAUSE
SOLUTIONS
ON/OFF switch is switched on,
LED does not light. Buzzer is
off. There is no AC voltage
There is no voltage at the DC
input Terminals
1. Check the continuity of the
battery input circuit
2. Check that the battery fuse is
intact. Replace if blown
3. Check that all connections in
the battery input circuit are tight
Polarity of the input voltage has
been reversed that has blown the
DC side fuses.
(
Note: Reverse polarity may
cause permanent damage)
Correct the polarity of the input
connections and replace the
fuse.
If the unit does not work after
replacing the fuse, the unit has
been permanently damaged
Call Technical Support
Buzzer alarm is sounded 1
time. There is no AC voltage.
1.Loose AC output connections.
2.Short circuit of AC Output
wiring.
1.Tighten AC output connections
2.Check AC wiring for short
circuit.
Buzzer sounds 2 times
and Red LED blinks 2
times
every
eight
seconds
Voltage at the DC input
terminals reads below;
10.8±0.2VDC(12V version),
21.6±0.4VDC(24V version),
43.2±0.8VDC(48V version).
1.Check that the battery is fully
charged. Recharge if low.
2. Check that the battery cables
are thick enough to carry the
required
current
over
the
required length. Use
thicker cables if required.
3. Tighten connections of the
battery input circuit
