3.2 SAFETY INSTRUCTIONS FOR PROTECT C
This chapter contains important instructions for the PROTECT C UPS
and its external battery modules (special accessories). These must be
followed during assembly, operation and maintenance of the
uninterruptible power supply and the battery systems (internal and, if
appropriate, external as well).
The UPS carries high voltage. Danger!
The unit may only be opened
by trained and qualified personnel. Repairs may only be carried out
by qualified customer service staff!
The output may be live, even if the UPS is not connected to the mains,
since the UPS has its own internal power supply (battery)!
The equipment must be
properly earthed in order to protect personnell!
PROTECT C may only be operated with or connected to a 220 V / 230 V
/ 240 V mains with protective grounding using a CE marked mains
connection cable with PE conductor (included in the delivery) that has
been tested in accordance with national standards.
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 C is exhausted or when the UPS is not working in its normal
mode (see also chapter 9.1.1, Page 111).
