Introduction
These operating instructions contain all the information needed to install and
operate the UPS.
The uninterruptible power supply (UPS) is connected between mains and
the electrical load. It protects the load from mains interruptions, especially
power failures.
This UPS operates according to the on-line principle. This means that the
connected loads are supplied via the inverter of the UPS. This protects the
load from mains supply disturbances and provides a secure mains supply
for electrical loads (PCs, network servers, multi-console systems).
In case of a mains failure, the built-in, maintenance-free batteries provide
uninterrupted power to the loads. In actual use, mains failures are, depend-
ing on the quality of the mains supply, relatively short in duration. Thus, the
power supplied by the UPS is adequate to allow work to continue on your
computer system until mains voltage has been restored. In the event of an
extended mains failure, you should nevertheless store your data and discon-
tinue your work.
You will be alerted by means of acoustical (buzzer) and optical (LED) alarms
contained in the UPS that a mains failure has occurred or is occurring. Listed
below are procedures which are intended to assist you in determining how
critical it is that work be discontinued in the event of an extended mains fail-
ure.
Which procedure you select depends primarily on the length of time required
to safely end your application and shutdown your operating system.
• In the extreme case, it is possible to work on a UPS-protected PC until
the battery has reached its minimum power level. In the event of a
mains failure, an acoustical signal is output by the UPS every 4 sec-
onds; if the minimum power level of the batteries is nearly reached,
this signal is output every second. This procedure is, however, seldom
required. While battery recharging begins immediately following resto-
ration of the mains supply, the procedure may require several hours to
complete.
