The UPS operates with mains, battery or bypass power. It contains components that carry high currents
and voltage. A properly installed enclosure is earthed and IP20 rated against electric shock and unwanted
objects. The UPS is a sophisticated power system and only qualified personnel are allowed to 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 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.
