Installation
W A R N I N G
This UPS contains its own energy source (batteries). The output receptacles may carry live voltage even when the UPS is not connected to an AC supply.
Do not remove or unplug the input cord when the UPS is turned on. This removes the safety ground from the UPS and the equipment connected to the UPS.
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled, indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40°C (104°F). Do not operate near water or excessive humidity (95% max).
To comply with international standards, the sum of earth leakage current from the load connected to the UPS must not exceed 1 mA.
NOTE Do not make unauthorized changes to the UPS; otherwise, damage may occur to your equipment and void your warranty.
