This section provides step-by-step instructions for starting your
Powerware 9170 system. Follow these procedures closely to avoid
potential damage to your equipment or the UPS and to protect yourself
and others from hazardous operating conditions.
C A U T I O N
S 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 system can 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 the DC disconnect switch in each battery cabinet or unplug all
battery strings in each battery cabinet.
S 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).
