WARRANTY CONDITIONS
BATTERY SIZING
It is important to match your Battery size according to the power rating of
the Inverter.
To ensure peak performance, it is important to choose the right Battery for
your Inverter. The Battery size required will depend on the load and intended
running time. Use this formula as a general guide:
Recommended Battery Size= Inverter rating in watts ÷ input voltage × 10
e.g. 1200W ÷ 12V x 10 = 1000Ah
Minimum Battery Size = Inverter rating in watts ÷ input voltage × 3
e.g. 1200W ÷ 12V x 3 = 300Ah.
Do not use an undersized Battery as this may result in an Inverter that does
not start or that will rapidly discharge the Battery and may cause damage to
the Battery.

MAINTENANCE
Battery Terminals require frequent care and maintenance. Very high current
(up to several hundred amps), is drawn by the Inverter when starting
electrical motors and other high power appliances. We recommend an
inspection of the Batteries and the interconnecting cable connections once
every 1-3 months or as recommended by the Battery manufacturer.
1. Regularly check all connections; make sure they are always tight.
Battery terminals are made of soft lead which will slowly compress over
time eventually causing loose connections.
2. Check all connections are free of corrosion. Remove any corrosion and
coat the terminals with Vaseline or grease to help prevent future
corrosion.
3. Take specific gravity or SG readings of each cell using a hydrometer to
check the level and performance of each Battery. Alternatively a Battery
Voltage reading for each cell will suffice but may not be accurate for
multiple Batteries connected in parallel. Report any serious imbalance to
your system installer or Battery supplier for corrective action.
SAFETY
When working on Batteries protective clothing and eye wear should be
worn. Extreme care should be taken not to short circuit any Battery
terminals especially with tools. If in doubt have the work carried out by
qualified personnel.

DIP SWITCH SETTINGS
FAULT FINDING
Should the Inverter appear to be malfunctioning we suggest the
following to eliminate any external problems:
1.
Turn the Inverter “OFF” via the Circuit Breaker switch on the front
panel.
2.
Disconnect all AC wiring from the Inverter.
3.
Disconnect DC Battery leads from Battery. Clean all terminals by
removing all grease/corrosion on both DC leads and Battery
terminals.
4.
Ensure you have sufficient Battery capacity at the nominal voltage
(specified on the compliance label of your Inverter).
Please note: Use minimum 100AH Battery or the size of
a substantial Car Battery.
5.
Make connection directly to Battery terminals and ensure all
connections are tight.
6.
Remove other wiring from the battery to unsure that the Inverter is
the ONLY device connected to battery bank.
7.
Ensure Battery voltage is within the correct limits as outlined in the
section INVERTER SPECIFICATIONS of this manual. If you do not
have a DC voltmeter or multimeter check the front panel for
Overvolts and Undervolts LED’S.
8.
Turn the Inverter ON via the Circuit Breaker switch on the front panel.
Observe the lights on the front left of your Inverter. Refer to
INVERTER OPERATION sections for explanation of Indicator lights.
9.
Plug in various appliances and monitor the Inverters operation.
HELPFUL HINTS
*
Remember that the Inverter automatically starts when a load is
applied.
*
Make sure leads and terminals are not corroded or faulty in any way.
*
Make sure the Inverter goes into STANDBY with no load switched
on.
*
Make sure the Circuit Breaker is reset properly. If unsure switch OFF
and ON again.
16
In order to access these options you have to open the Inverter. Before
altering the settings switch Inverter OFF, adjust the setting and switch
Inverter back ON again. We recommend these adjustments be carried out by
qualified personnel or your system installer.

Automatic Reset
OFF=Disabled

This feature is designed to restart the Inverter and maintain power in the
event of an external fault. Should the Inverter shut down due to under
voltage, over temperature or any fault condition it will attempt to reset every
8 minutes until the fault condition clears and normal operation resumes.
For overload shutdown the Inverter will only attempt 5 restarts. If the
Inverter can not resume normal operation within 5 restarts, it will remain
OFF until reset manually. This prevents continuous re-application of power to
faulty appliances or wiring.
For under voltage shutdown the Inverter will restart when the battery
voltage reaches the reconnect value as shown in the table 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.
Separate DC and AC wiring. Avoid running DC and AC cables in the
1.
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.
Minimize length of DC cabling. DC cables can act as an aerial, therefore
2.
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.
240Vac Earth. For household installations, it is recommended that a
3.
“good” Earth Stake is located as nearby the Inverter as is possible.
AM and HF Radios. These types of radio equipment inherently suffer
4.
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.
Televisions. TV signals are transmitted as FM waveforms. This type of
5.
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.
Mobile Installations. Due to the limitations of this type of installation, the
6.
best results for the minimization of RFI are usually obtained by maximizing
the distance between the Inverter and the Radio/Television.
14
AUTOMATIC AC TRANSFER SWITCH
(Option)
Eliminates the need to manually switch your power source between
Inverter and Generator. The Transfer Switch automatically senses
Generator AC power and switches the output between Inverter and
Generator accordingly.
Have this option fitted to your LS series Inverter to minimise your power
system wiring. Simply connect the Generator to the hardwire terminals.
Features
*
Available exclusively to the new LS series from 2000W to
7000W models.
*

SAFETY
ON DELAY TIMER AND VOLTAGE INTERLOCK MODULE
This module is available with the automatic AC Transfer Switch option for
the LS series Sine Wave Inverter models from 2000W to 7000W. It offers
further protection to connected appliances from Generator voltage
fluctuations and ensures a more stable AC supply.
Upon the starting of a Generator the output voltage will rise and stabilise
as the Generator speed increases. Once the Generator voltage is within
the required limits the timer provides a short delay before switching the
Generator power to the AC output. This ensures the Generator is warmed
up and the output voltage is stable. The Generator output voltage is
continuously monitored and if it is outside the set limits the transfer switch
will switch back to the Inverter. This prevents problems due to low voltage
and overvoltage surges, which can harm appliances.
Inverter Isolation and Safety
*
All Latronics Inverters have an isolation rating of 3500V between AC
and DC via the toroidal transformer, which ensures extremely safe
and risk free operation.
*
All the switching electronics and control circuitry are on the DC input.
*
The single pole Circuit Breaker assembly ensures that when the
Inverter is switched OFF, it is isolated from the Battery supply.
Please refer to relevant Australian Standards for safety procedures.
AC WIRING
On Delay Timer - ensures the Generator has warmed up and the output
voltage is stable before the transfer switch is activated.
*
Voltage Interlock - monitors the Generator output voltage. If too high or
too low the Transfer Switch reverts back to the Inverter output until the
generator output re-stabilises.
*
Versatile - selectable voltage levels and time delay.
*
*
Note: Highly recommended for Generators with large fly wheels that
ramp up and down slowly at start up and shut down.
*
*
Make sure the Inverter is switched OFF before working on the mains
wiring. Turn the circuit breaker switch into OFF position.
The active and neutral of the 230V AC output are electrically isolated
from the battery negative, battery positive, and earth connections.
The Inverter AC output is connected directly to the Transformer output
winding.
Latronics Inverters have the AC output (active and neutral) floating
with respect to the DC and Earth. The Earth connection is connected
to the case only. This configuration provides the highest safety and
most flexibility for installation wiring.
Latronics Inverters are suitable for MEN connection.
The Earth is connected internally to the Inverter case.
Ensure that power will never be fed into the Inverter AC output Junction
Box from the Mains or Generator. This would result in the destruction of
the unit and will not be covered by warranty.
Settings are adjustable via DIP
switches located inside the
Generator Input Junction Box.
ENSURE POWER IS DISCONNECTED BEFORE ADJUSTING DIP SWITCHES.
To be adjusted by qualified personnel only!
Available for LS series models from 2000W to 7000W

WARNING:
The Inverter output is just as lethal as normal mains electricity
It is important that all AC wiring complies with the requirements of the
relevant wiring standards, (AS 3000).
Any work carried out on AC/Mains wiring is to be performed by
Qualified and Licensed personnel only.

INVERTER OPERATION
When the Inverter is switched on all 3 LED'S light up for 1 second
while the microprocessor performs a start up and system check
procedure.
Standby/230 volts (Green LED)
This LED flashes when in Standby mode
(i.e. no loads connected). When a load is
applied the LED will illuminate continuously to
indicate that 240V AC is being supplied.
Circuit Breaker ON/OFF Switch
The Circuit Breaker is designed for ease of operation and safety. By pushing the
switch “UP”, the Battery supply is connected to the Inverter. The Circuit Breaker
will turn OFF automatically if too large a load is left on the Inverter continuously.
Reset the switch after allowing approximately 5 minutes to cool. If the Inverter
shuts down due to overload, undervolts or overvolts it can be reset by turning the
Circuit Breaker OFF, waiting 10 seconds (or until LED goes out), then turning it on
again.
Hardwire - 3 Terminal
Output Junction Box
For distribution of AC
output power.
Over temp./Over load (Red LED)
If the internal temperature exceeds safe operating
limits of the components for more than five
seconds, the Inverter will shut down in Over
temp with this LED on continuously.
Allow 5 minutes for the Inverter to cool and reset
the unit. If the APPLIED load demands more
current than the Inverter can safely supply for more
than 5 seconds, the Inverter will shutdown in Over
load and this LED will flash.
Battery Leads
RED = Battery positive.
BLACK = Battery negative.
Undervolts/Overvolts (Red LED)
In order to protect the battery the Inverter will
shutdown after 5 seconds if the battery voltage
falls below its limit, (Undervolts), or exceeds the
maximum, (Overvolts), as specified in the
Electrical Specifications table.
For Undervolts the LED will remain on continuous,
while for an Overvolts situation the LED will
continue to flash.
Hardwire - 3 Terminal
Input Junction Box
For connection of AC Input
Power e.g. from Generator.
(Available only when AC
Transfer Switch option is fitted).
AutoStart Sensitivity Adjustment
The screwdriver adjustment slot permits
the operator to adjust sensitivity between
0- 20W. Due to lengthy 240V AC cables the
Inverter may sense fake loads. To combat
this, turn the control clockwise. Alternatively
turning the control in the opposite direction
increases sensitivity. Turning the control fully
anti-clockwise will disable the Auto Start feature
and the Inverter will remain constantly ON.
10
11
Fan
If the temperature inside the Inverter
reaches preset levels, the dual speed
fan will switch on initially in low
speed and then into high speed if
the temperature continues to
increase. Obstruction of the air
intake and output will reduce the
power rating of the Inverter.
