●The unit must be placed in a well-ventilated area, not exposed to the open environment, and
free from contaminates (i.e. exhaust gases, sea air, battery gases, dust).
●The LS inverter is of protective class I meaning the case must be earthed. This should be
attached using the earth connection on the a.c. output junction box.
●A space of 10cm is needed on each side of the inverter for adequate transfer of internal heat.
●The inverters inputs and outputs are classied as over voltage category II.
For more information on over voltage category, see page 17
●The inverter can be mounted horizontally on table or oor. The inverter can also be mounted
on a wall, taking note of the sticker being the correct orientation.
●Ensure the mounting surface is structurally sound.
●All fasteners should be rated to carry a minimum of 40kg.
●Inverter must not be:
Installed in direct sunlight.

INSTALLATION
To install the inverter please follow the instructions on the following pages. If you are unsure of
any aspect of the installation please email or call Latronics.
Considerations Before Install
Slots for easy mounting
Mount two xing to the wall
Slot the inverter on
Fixings and mounting
Ensure at least 3 xings are used at the
top and at least two at the bottom.

INSTALLATION
DC Wiring
●The inverter is designed to operate on a battery supply only.
●For best performance, the unit should be placed as close as possible, but not directly on top
of the battery supply.
●The inverter d.c. input voltage is stated on the identication label of the inverter. Check that it
is the same voltage as the battery supply.
●Ensure the inverter is switched OFF before connecting the d.c. supply. Turn the circuit
breaker switch to the OFF position.
●Connect the inverter DIRECTLY to the battery terminals for best performance.
●Input leads marked RED = (positive), & BLACK = (negative).
●The inverter is tted with a circuit breaker in line with the battery positive lead, which can
negate the need for a battery fuse. (Check regulations)
●Maximum input current is limited by inbuilt circuit breaker. Please check nameplate for
rating of circuit breaker.
●Interruption capacity of inbuilt circuit breaker is 4.5kA.
●Ensure you check the short circuit current of the battery bank. If the short circuit current is
more than 4.5kA you must install an appropriately rated external circuit protection device.
OBSERVE POLARITY
Cables connecting the inverter to the battery are designed to achieve
maximum eciency and output power:
DC CABLES SHOULD NOT BE EXTENDED
Battery Sizing
●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. ( 2000W ÷ 12V ) x 10 = 1666Ah
●Minimum battery size = Inverter rating in watts ÷ input voltage × 3
e.g. ( 2000W ÷ 12V ) x 3 = 500Ah.
●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.
5
INSTALLATION
AC Wiring
●Make sure the inverter is switched OFF before working on the mains wiring. Turn the circuit
breaker switch into OFF position.
●Ensure that the a.c. wiring is separated from the d.c. wiring to reduce the occurrence of noise
in the installation.
●In standard Latronics inverters the active and neutral of the 240V a.c. output are electrically
isolated from the battery negative, battery positive, and earth connections.
●The inverter a.c. output is connected directly to the transformer output winding.
●Standard Latronics inverters have the a.c. output (active and neutral) oating with respect to
the d.c. and earth. The earth connection is connected to the case only. This conguration
provides the highest level of safety and most exibility for installation wiring.
●The protective earthing connection should be attached to the earth terminal of the a.c.
output junction box.
●When using an inverter with a transfer switch ensure that no highly inductive or capacitive
loads are present such as pumps, compressors or similar. The reason for this is that transfer
from an unsynchronised source can produce large spikes that can feed back onto the
inverter and damage it.
●Ensure that power will never be fed into the inverter a.c. output junction box from
the mains or generator. This would result in the destruction of the unit and will not be
covered by warranty.
●Latronics inverters are suitable for use with type A and type B RCD’s.
●Latronics inverters are suitable for MEN connection.
●The earth is connected internally to the inverter case.

WARNING
The inverter output is just as lethal as normal mains electricity.
It is important that all wiring complies with the requirements of the
relevant wiring standards. Any electrical work carried out on a.c./mains
wiring and d.c. wiring is to be performed by suitably qualied electrical
worker.
Systems with solar panels, when exposed to light, supply d.c. voltage.

INSTALLATION
Other Safety Considerations
●If the inverter is used in a manner not specied in this manual or by Latronics, protection
provided by this equipment may be impaired
●All standard Latronics inverters have an isolation rating of 3500V between a.c. and d.c. via the
toroidal transformer, which provides safe operation.
●All LS series inverters have short circuit protection which limits the maximum fault current to
the 5 sec. surge rating of the inverter.
●All the switching electronics and control circuitry are on the d.c. input.
●For 12V, 24V and 48V d.c. inverters the circuit breaker assembly isolates the positive pole
only from the battery supply.
●For 72V, 96V and 110V, 120V and 125V d.c. inverters the circuit breaker assembly isolates the
positive and negative pole from the battery supply.
●If the battery voltage drops below nominal voltage this can eect the output voltage. If you
have loads that are sensitive to low a.c. voltages please ensure the battery voltage is never
able to drop below nominal voltage.
●All LS inverters contain double insulated mains frequency transformers.
●There are Y2 capacitors installed across active-earth and neutral-earth and are required for
EMC. These capacitors can establish a voltage divider which shows on some multimeter’s as
a voltage from earth-active and earth-neutral.

BATTERY MAINTENANCE AND SAFETY
Battery Safety
●Remove watches, rings, or other metal objects.
●Use tools with insulated handles.
●Wear rubber gloves and rubber soled boots.
●Do not lay tools or metal parts on top of batteries.
●Disconnect charging source prior to connecting or disconnecting battery terminals.
●Determine if battery is inadvertently grounded. If inadvertently grounded, remove the source
from the ground. Contact with any part of a grounded battery can result in electrical shock.
●The likelihood of such shock can be reduced if such grounds are removed during installation
and maintenance.
(Applicable to equipment and remote battery supplies not having a rounded supply circuit)
●When working on batteries protective clothing and eye wear should be worn.
●When replacing batteries, replace with the same type and number of batteries or battery
packs. Consult with the battery manufacturer for more information on replacement.
●CAUTION: Do not dispose of batteries in a re. The batteries may explode.
●CAUTION: Do not open or damage batteries. Released electrolyte is harmful
●If in doubt have the work carried out by a suitably qualied electrical worker.
CAUTION
A battery can present a risk of electric shock and high short-circuit
current. The following precautions should be observed when working on
batteries

BATTERY MAINTENANCE AND SAFETY
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
powered 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 often
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 specic 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 suce
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.

INVERTER OPERATION
LED Indicators
Standby/Power (Green LED)
This LED ashes when in standby mode
(i.e. no loads connected). When a load is
applied the LED will illuminate continuously to
indicate that 240V a.c. is being supplied.
Over temp/Over load (Red LED)
If the internal temperature exceeds safe operating limits of
the components for more than ve seconds, the inverter
will shut down in over temp with this LED on continuously.
Turn the ON/OFF switch o and allow 5 minutes for the
inverter to cool, then turn it back on. 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 ash.
Auto Start Sensitivity Adjustment
The screwdriver adjustment slot permits the operator to
adjust sensitivity between 0- 20W. Due to lengthy 240V a.c.
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.
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 specied in the
specications table on page 22. For undervolts
the LED will remain on continuous, while for an
overvolts situation the LED will continue to ash.
