INVERTER EPM 250 / 500 / 1000

DESCRIPTION

            The inverter uses PWM control for voltage / over current control & comes on instantly  during mains failure to feed power to predetermined points which are connected to the inverter through a single wire and when the mains supply is resumed the inverter automatically  goes off and the load is connected to the mains supply.

              The battery charging is controlled  through an intelligent battery charging circuit.

The front panel of the inverter has,

1.        Inverter Cut - Push to on  / Push to off switch along with a Red LED above .  This feature is provided
            to conserve battery power in case of power failure.
           
2.        Yellow, Green & 2 Red LED's indicating Batt. Chg., Mains, Standby & Overload status respectively.
            Red LED lights up during power failure, Green when the mains supply is present & Yellow whenever
            the battery is being charged. A programmed intelligent charger takes care of the charging cycle.

            The overload Red LED blinks during excess load conditions & stops once the excess load is
            withdrawn.

The Rear panel has,

1.          Connector for making connections to the battery alongwith a FUSE inline & a 5A socket to connect
             the load.

MAINTENANCE & PRECAUTIONS

1.        Fuse is provided at the rear of the inverter & has to be replaced by 26 SWG / 22 SWG tinned copper
            wire only (supplied in ample quantity with the inverter). Do not use thicker gauge or eliminate the fuse,
            as this will have a damaging effect on the inverter.
             
2.        Electrolyte level in all the cells of the battery is to be topped up as & when required to 1/2" (approx.)
            above the plates with battery water commonly available at petrol pumps. Do not run the battery dry,
            as this will cause irreversible damage to the battery and the load handling capacity will be decreased
            drastically. Also do not overfill till the cap level (at the top) of the battery.

3.        Vaseline (White petroleum jelly) has to be applied regularly to the battery terminals. If the terminals are
            dirty / sulphonated then clean them before applying vaseline. A situation of dirty terminals should never
            arise, as it will drastically affect the performance of the inverter.

4.         During terminal cleaning / battery water top up, the system may be disengaged by removing the fuse
            link on the rear of the inverter.

5.        Do not attempt to shift the inverter (electrically) from its installed point, kindly consult us if it has to be 
           shifted to another electrical point.

6.        Do not spill water on the inverter or the battery, as it will damage the circuitry inside. 

7.        Do not cover the inverter or the battery. In case it has to be covered / housed, provide ample ventilation, 
            this is very essential.

8.        Do not take naked flame (lighted candle, match stick etc.) near the battery to check the water level etc.
            as it will cause the battery to catch fire.

9.        At the time of installation the recommended load (as per actual current drawn) has been informed to you,
            kindly adhere to the suggested load pattern to ensure optimum performance of the system.

10.       Do not take out the AC plug of the inverter mains supply, because when removed it carries the AC
            voltage generated by the inverter & if the plug pins are touched it gives a terrible shock. Hence if the
            plug has to be taken out then first remove the fuse link provided at the rear of the inverter to avoid shock
            / accident.
