WARNING
The UPS is powered by its own energy source (batteries). The output
terminals could be energized even when the UPS is disconnected from
an AC source. To reduce the risk of fire or electric shock, install the UPS
in a temperature and humidity controlled, indoor environment that is free
of conductive contaminants. See temperature and humidity limits in
Technical data
.
The ambient temperature limit must not be exceeded. Do not operate the
UPS near water or excessive humidity. The system is not intended for
outdoor use.
Before you start any installation or service work, make sure that all AC
and DC power sources are disconnected. Power can come from multiple
sources. Also ensure system grounding / PE continuity.
In a parallel system, the output terminals could be energized even when
the UPS is turned off.
WARNING
Batteries present a risk of electrical shock or burn from high short-
circuit current. Obey proper precautions.
Electric energy hazard. Do not attempt to alter any battery wiring or
connectors. Attempting to alter wiring can cause injury.
Do not open or mutilate batteries. Released electrolyte may be toxic and
is harmful to the skin and eyes.
Batteries can contain HIGH VOLTAGES, and CORROSIVE, TOXIC and
EXPLOSIVE substances. Because of the battery string the output
terminals can carry high voltage even when the AC supply is not
connected to the UPS. Read the shutdown instructions carefully.
IMPORTANT: The battery may consist of multiple parallel strings. Make
sure that you disconnect all strings before installation.
