HARDWARE INSTALLATION GUIDE
1. Your new UPS may be used immediately upon receipt. However, recharging the battery for at least 8 hours is recommended to ensure
that the battery's maximum charge capacity is achieved. Charge loss may occur during shipping and storage. To recharge the battery,
plug the UPS into an AC outlet. The unit will charge in both the on and off position.
2. With the UPS turned off and unplugged, connect the computer, monitor, and any equipment into the battery power supplied outlets.
DO NOT plug a laser printer, copier, space heater, vacuum, paper shredder or other large electrical device into the battery
power supplied outlets. The power demands of these devices will overload and possibly damage the unit.
3. Plug the UPS into a 2 pole, 3 wire grounded receptacle (wall outlet). Make sure the wall branch outlet is protected by a fuse or circuit
breaker and does not service equipment with large electrical demands (e.g. air conditioner, refrigerator, copier, etc. Avoid using
