AEG PROTECT B. 750 Operating Instructions Manual page 11

The output may be live, even if the UPS is not
connected to the mains supply, as the UPS has
its own internal power supply (battery)!
For health and safety reasons, the unit must be
earthed correctly!
PROTECT B. may only be operated with or connected to a
230 Vac mains with protective grounding using a mains
connection cable with PE conductor (included in the delivery)
that has been tested in accordance with German standards
(VDE).
Danger! Risk of burning!
The battery has powerful short-circuit currents.
Incorrect connection or isolation faults can lead
to melting of the plug connections, sparking
potential and severe burns!
The unit has a warning signal that sounds when
the battery voltage of PROTECT B. is exhausted
or when the UPS is not working in its normal
mode.
Observe the following safety instructions to
ensure permanent operational safety of and safe
work with the UPS:
♦
Do not dismantle the UPS! (The UPS does not contain
any parts which require regular maintenance. Bear in
mind that the warranty will be invalidated if the unit is
opened!)
♦ Do not install the unit in direct sunshine or in close
proximity of heaters!
♦ The unit is designed to be installed inside in heated
rooms. Never install the UPS in the vicinity of water or in
an excessively damp environment!
♦ Condensation may occur if the UPS is brought from a cold
environment into the room where it is to be installed. The
UPS must be absolutely dry prior to start-up. As a result,
leave it to acclimatize for at least two hours.
