Installation-Connecting the UPS

These UPS are equipped to work with power supply with wide voltage range 135 ~ 300V AC, 50Hz ± 5%. Plug the UPS into a two pole,

three wire, AC wall socket outlet equipped with an earth connection.

* Do not use extension cords. * Do not plug appliances such as electric heaters, toasters and vacuum cleaners into the UPS. * Do not

plug/unplug the input cord when the UPS is switched ON.

Charging the Battery

Before initial start/first time use it is recommended that the UPS may be connected to mains and battery should be

charged for 6 ~ 8 hours for optimum use. The UPS charges its battery whenever it is connected to mains. For best

results charge the battery before use.

Connecting the Loads

Plug the loads through the output socket of the UPS. Now, you can switch ON the loads/devices as per your requirement.

UPS suitable for the best load.

Note :

1. Do not connect a laser printer to the UPS. A laser printer periodically draws significantly more power than when idle and will over load the UPS.

2. The UPS output can be used only for electronic loads such as : computers.

3. In case of fuse blown out please replace the fuse with same type and rating only.

Caution : 1. Never touch the contents of fuse or sockets when the mains plug is connected OR the UPS is Switched ON.

*May not work with certain configurations.

2. These UPSs are designed to operate from 230V, 50Hz, Sinewave Power Supply available from Electricity Boards. No Power-

conditioning device like Stabilizer/CVT should be connected with the UPS.

3. Abnormal voltages may appear at the output of UPS if it is driven from non-sinusoidal source like Inverter/Portable Generator

etc. These voltages may be potentially harmful for the loads, other than Computers/SMPSs, connected to the output of UPS.
