INSTALLING YOUR UPS SYSTEM (continued) 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 Primary Serial Port (I), one Secondary Serial Port (II), and one USB port to allow connection and communication between the unit and any attached computers. The Primary Serial Port (I) 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 thePowerPanel® Business Edition Software. The Secondary Serial Port II, only allows the UPS to initiate the connected computer's graceful auto-shutdown in case of an emergency. Note: If the USB port is used, the serial port(s) will be disabled. They cannot be used simultaneously. Note: PowerPanel® Business Edition Software is available on our website.
