AC WIRING
Both models require an external 10A circuit breaker for protection of
inverter’s AC input. Usually mounted in main switchboard. The active and
neutral of the AC output are electrically isolated from the DC inputs and earth
connections.
Latronics Inverters have the AC output (active and neutral) floating with
respect to the DC and Earth. This configuration provides the highest safety
and most flexibility for installation wiring. The earth
is connected internally
to the Inverter case and is suitable for
wiring.
The unit is supplied with both male and female 20Amp Wieland Gesis
lockable AC connectors that
To install connectors read the following procedure.
1. Make sure Inverter is switched OFF before working on mains wiring. Turn
external AC Circuit Breaker switch into OFF position and
make sure it cannot be switched back on.
2. Test the wiring with a voltmeter to make sure no voltage is present.
3. Peel back 30mm of cable jacket and cut Active and Neutral cables
5mm shorter than Earth.
4. Strip 5mm off all three cables.
5. Take the Wieland Gesis connector, disassemble into three main sections
and insert stripped wire through as shown below.

RADIO FREQUENCY INTERFERENCE
Radio Frequency Interference (RFI) is a phenomenon that exists in modern
society and is a problem in many areas of electronics. For Inverter users,
RFI normally presents itself in the form of static and/or interference when
listening to an AM radio and in unusual cases may interfere with TV reception.
Over the years Latronics has continued to invest significant time and effort in
the reduction of RFI related emissions from the entire product range, so that
they comply with the appropriate International and/or Australian Standards.
Even with this compliance, there are situations where RFI may still be a cause
for concern, and can differ greatly from installation to installation. Accordingly,
the following is a list of recommendations made to assist in the overall
reduction of RFI.
1.
Avoid running DC and AC cables in the
same conduits and/or cable trenches. It is strongly recommended that
DC and AC wiring be separated by the greatest distance possible. In
extreme cases, the use of shielded conduit may be necessary.
2.
. DC cables can act as an aerial,
therefore all such cables should be kept as short as is practicable. For
best performance minimize DC cable length to Inverter and Batteries and
if possible avoid the use of auxiliary DC loads.
3.
. For household installations, it is recommended that a
“good” Earth Stake is located as nearby the Inverter as is possible.
4.
These types of radio equipment inherently suffer
from all forms of RFI, especially when the received signal level is weak.
In such cases reception can sometimes be improved by relocation of the
radio itself, alternatively the use of an appropriate external antenna and
co-axial cable
may be necessary. External antennas should be located
in a manner that ensures maximum signal strength whilst affording the
greatest possible distance away from the Inverter and Batteries.
5.
TV signals are transmitted as FM waveforms. This type of
signal fundamentally reduces the effects of RFI, therefore the use of a
good antenna and feeder cable is normally sufficient to ensure quality
reception. Locating the television as far as possible from the Inverter may
also improve picture clarity.
