5. Press the power switch to turn the UPS on. The Power-On indicator light will illuminate. If an overload

is detected, an audible alarm will sound and the UPS will emit one long beep. In order to reset it, turn

the unit off and unplug some equipment from outlets. Make sure the total load of the equipment

connected to the UPS is within the unit’s safe range, (refer to the technical specifications), and then

turn the unit on.

6. To maintain an optimal battery charge, leave the UPS plugged into an AC outlet at all times.

7. Before storing the UPS for an extended period of time, turn the unit OFF. Then cover it and store it

with the batteries fully charged. Recharge the batteries every three months or so, to ensure good

battery capacity and long battery life; further, this might also prevent damage to the unit from an

unlikely battery leakage.

8. The unit provides one Serial port and one USB port to allow connection and communication between

the unit and any attached computers. The Serial Port as well as its paired USB port allow for

bi-directional communication among the UPS and the primary connected computer running the

PowerPanel

Business Edition Software. The computer can monitor the UPS and alter its various

programmable parameters. When there is a power failure, the computer connected to the port will

start to shut down after a user controlled delay based on the settings given to the PowerPanel®

Business Edition Software.

Note: If the USB port is used, the serial port will be disabled. They cannot be used simultaneously.

Note: PowerPanel® Business Edition Software is available on our website. Please visit
