This UPS contains its own energy source (batteries). The output receptacles
may carry hazardous voltage even when the UPS is not connected to an AC
supply. When AC input voltage is present, the Powerware 9170
provide output voltage even though its batteries are disconnected. To
confirm that there is no UPS output voltage, always disconnect all of the AC
input sources and unplug all strings of internal battery modules; if the UPS
has one or more separate battery cabinets, open (push in) the DC
disconnect switch button on each battery cabinet or unplug all battery
strings in each battery cabinet.
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).
For optimum battery life, ambient temperature should not exceed 25°C
(77°F). Battery life is substantially reduced if ambient temperature is higher.
