INSTALLATION

• Ensure the inverter has not been damaged in transit.

•  The inverter must not be installed outside

• The unit must be placed in a well-ventilated and protected area, not exposed air, battery gases, dust, ants).
  to the open environment, and free from contaminants (i.e. exhaust gases, sea

• A space of 10cm is needed on each side of the inverter for adequate transfer internal heat.

• The inverter can be mounted horizontally on a table or floor. The inverter can also be mounted on a wall, taking note of the sticker being the correct orientation.

• For best performance, the unit should be placed as close as possible, but not directly on top of the battery supply.

•  The inverter DC input voltage is stated on the identification label of the inverter. Check that it is the same voltage as the battery supply.

• The inverter is designed to operate on a battery supply only.

• The inverter is fitted with a circuit breaker in line with the battery Positive Lead, which may reduce the need for a battery Fuse.

• Ensure the inverter is switched OFF before connecting the DC supply.
  Turn the circuit breaker switch to the OFF position.

• Connect the inverter DIRECTLY to the battery terminals for optimal performance.

• Input leads marked RED = (positive), & BLACK = (negative).

OBSERVE POLARITY

N.B. Ensure sufficient battery capacity to match load requirements!

BATTERIES

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 and inverter.

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 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

Dip switch settings apply to all models from 1000W-1800W inclusive.
In order to access these switches you have to open the inverter. Before altering the settings, switch the inverter OFF, adjust the setting and switch the inverter back ON again. We recommend these adjustments be carried out by qualified personnel or your system installer.
SW1 Hz 50/60 Hz
ON = 50Hz (factory setting) OFF =60Hz
If you need to operate American or Japanese equipment this option will allow your inverter to operate at 60Hz.
SW3 SP Special
SW2 & SW4 AR Automatic Reset
OFF=Disabled ON=Enabled (factory setting)
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.
SW5 & SW6 UV Under Voltage Settings
SW5 OFF & SW6 OFF= (factory setting)

DIP SWITCH LOCATION

WARNING:
Due to dangerous voltages existing inside the unit, make sure the circuit breaker switch is turned off before opening the unit. Should you have any doubt about performing these modifications, we strongly recommend the use of a qualified trades person.
AUTOMATIC AC TRANSFER SWITCH (Option)

This 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.
Features

• Available exclusively to the LS series from 1000W to 1800W models.
• No Break changeover time of 0.02 second (< one cycle).

Please Note: The AUTOMATIC AC TRANSFER SWITCH is available as a separate device the ACTS40 or ACTS40PM Panel Mount.
If you are using a transfer switch other than the Latronics brand please ensure you wait 5 seconds between switching from one source to another. Fash switching may damage the inverter.

• Installation of system components and associated interconnecting wiring, should be performed by qualified and licensed personnel only.

INVERTER OPERATION
When the inverter is switched on all 3 LEDs light up for 1 second while the microprocessor performs a start up and system check procedure.

INVERTER EFFICIENCY & OUTPUT WAVEFORM

SAFETY

inverter Isolation and Safety

• All standard 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

• Make sure the inverter is switched OFF before working on the mains wiring. Turn the circuit breaker switch into OFF position.
• In standard Latronics inverters 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.
• Standard 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.
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.

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.  Separate DC and AC wiring. 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.  Minimize length of DC cabling. 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. 230Vac Earth. For household installations, it is recommended that a “good” earth stake is located as nearby the inverter as is possible.
4. AM and HF Radios. 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. Televisions. 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.
6. Mobile Installations. Due to the limitations of this type of installation, the best results for the minimization of RFI are usually obtained by maximizing the distance between the inverter and the radio/television.

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 battery to ensure 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 over volts and Undervolts LEDs.

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.
• In extreme weather it is suggested to shutdown and unplug

INVERTER SPECIFICATIONS

APPLIANCES

Some appliances may have trouble running on inverters due to the current waveform they draw.
Certain appliances draw un-even load from a.c. supplies which from a mains supply might be OK but when operating from an inverter it may unbalance the internal toroidal transformer which can shut the inverter down. An example of an un-even current waveform is below

Some appliances that can cause this issue are

• Variable heat guns / hair dryers
• Washing machines / dish washers

This is not to say that the above appliances don’t work, just a very small amount of models that draw very uneven current.
This imbalance can be evened out by applying more load or trying a different model/brand.
If you are having trouble with a certain appliance please call Latronics for further assistance
