and Surge Protected Outlets”. The power demands of these devices will overload and possibly damage the unit.
3. Plug the UPS into a 2 pole, 3 wire ground-ed receptacle (wall outlet). Make sure the wall branch outlet is
protected by a fuse or circuit breaker and does not service equip-ment with large electrical demands (e.g. air
conditioner, refrigerator, copier, etc.). The warranty prohibits the use of extension cords, outlet strips, and surge
strips in con-junction with the UPS unit.
4. Press the power switch to turn the unit on. The Power On indicator light will illuminate green and the unit will
“beep” twice.
5. If an overload is detected, an audible alarm will sound and the unit will emit one long beep. To correct this, turn
the UPS off and unplug at least one piece of equipment from the battery power supplied outlets. Make sure the
circuit breaker is depressed and then turn the UPS on.
6. To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times.
7. To store the UPS for an extended period of time, cover it and store with the battery fully charged. While in
storage, recharge the battery every three months to ensure optimal battery life.
8. Ensure the wall outlet and UPS are located near the equipment being attached for proper accessibility.
