Operating instructions

18
The UPS is an electrical device that can be
dangerous. The device should only ever be
opened by specially trained technicians. Repairs
are to be made by qualified customer-service
personnel only!
The output can also be electrically charged, even if
the UPS is not connected to the mains power
supply. The UPS has its own internal power supply
(battery)!
To ensure operator protection, the device must be
properly grounded!
The PROTECT D must only be connected and operated with a
VDE-approved power cord with a grounding conductor to 220 V /
230 V / 240 V AC voltage networks with a protective ground.
Caution – Risk of burns!
The battery has a high short-circuit current. Any
incorrect connection or error made in disconnection
can lead to the melting of plug connections, to
arcing and to serious burns!
The device is equipped with a warning signal that
sounds when the PROTECT D battery power is
dead or when the UPS is not working in the normal
mode (also see Chapter 9.1.1 “Alarm / error
messages”, pg. 59).
To ensure operating safety with the UPS and the
battery modules (special accessory), please note
the following safety instructions:
 Do not attempt to open the UPS! (there are no parts in the
UPS that require regular servicing. Please note that if the
UPS has been opened, any warranty claims will no longer
apply)
 Do not expose the device to direct sunlight or a direct heat
source!
 The device is designed to be installed in heated rooms
indoors. Do not install the device close to water or in very
humid areas!
