that carry high currents and voltage. A properly installed enclosure is earthed
and IP20 rated against electrical shock and foreign objects. However, the UPS
is a sophisticated power system and only qualified personnel can install and
service it.
DANGER
This UPS carries lethal voltages. All repairs and service must be done by
authorized personnel only. There are no user-serviceable parts inside the
UPS.
WARNING
The UPS is powered by its own energy source (batteries). The output
terminals may be energized even when the UPS is disconnected from an AC
source. To reduce the risk of fire or electric shock, install this UPS in a
temperature and humidity controlled, indoor environment that is free of
conductive contaminants.
The ambient temperature must not exceed 40 °C (104 °F). Do not operate the
UPS near water or excessive humidity (95% maximum). 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 may come from multiple sources.
Also ensure system grounding / PE continuity.
In a parallel system, the output terminals may be energized even when the
UPS is turned off.
