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 all other wiring from battery to ensure that the Inverter is the ONLY device connected to the battery bank.
6. 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.
7. 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.
8. 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.

BATTERY SIZING
BATTERIES
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.
M AINTENANC E
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
Dip Switch Settings apply to all models from 1000W to 5000W inclusive.
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.

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. 240Vac 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.
16
AUTOMATIC RESET FEATURE
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 opposite.
5
AUTOMATIC AC TRANSFER SWITCH (Option code – KX)
Eliminate the need to manually switch your power source between Inverter and Auxiliary AC. The Transfer Switch automatically senses Auxiliary AC power and switches the output between Inverter and Auxiliary AC accordingly.
Take the hassle out of wiring a changeover switch between Inverter and Auxiliary AC. Have this option fitted to your IRM series Inverter to simplify your power system wiring. Simply connect the Auxiliary AC to the hardwire terminals, its that easy!
Features * Available exclusively to the IRM series from 500W to 7000W models * No Break changeover time of 0.02 second (< one cycle) * Single pole relay switching active * Minimise and simplify system wiring

AUTOMATIC AC TRANSFER SWITCH Continued.
The Automatic transfer switch option is available for all IRM Series inverters. 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.
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 recom m ended for Generators with large fly wheels that ram p up and down slowly at start up and shut down.
Settings are adjustable via Jumpers located on the inside of the Inverter on the blue circuit board.

SAFETY
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 Circuit Breaker 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.
* 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.
WARNING: The Inverter output is just as lethal as normal mains electricity, thus 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.
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.
POWER INDICATOR (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 230V AC is being supplied.
CIRCUIT BREAKER BATTERY ISOLATOR
ON/OFF Switch The circuit breaker is designed for ease of operation and safety. 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.
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.
10
AutoStart Sensitivity Adjustment The screwdriver adjustment slot permits the operator to adjust sensitivity between 0- 20W. Due to lengthy 230V 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.
