The PROTECT 1. may only be operated with or connected to a
three-phase power system with protective grounding using a
mains connection cable with PE conductor that has been tested
according to German standards (VDE).
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 1. is exhausted
or when the UPS is not working in its normal
mode (see also chapter 6.1 "Signalling”, page 47ff
and the following).
Observe the following safety instructions to
ensure permanent operational safety of and safe
work with the UPS and the battery modules
(special accessories):
♦ Do not dismantle the UPS!
(The UPS does not contain any parts that 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 housing 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 acclimate for at least two hours.
♦ Never connect the mains input and the UPS output!
♦ Ensure that no fluids or foreign bodies can penetrate the
housing!
♦ Do not block the air vents of the unit! Make sure, for
example, that children do not insert any objects in the
ventilation openings!
