For health and safety reasons, the unit must be
earthed correctly!
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 8 "Signalling”, page 47
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!
