Device Description of UPS
This manual is intended to provide basic information about single-phase offline
UPS systems, namely how they function, the application of different functions
and what you should do in the event of malfunctioning.
Furthermore, this manual contains instructions for the transport and storage as
well as the handling and installation of the UPS system.
The plan guidelines in this manual only relate to special requirements for the
UPS systems. During installation, make sure you follow the national and local
requirements for electrical installations.
The content of this device description may change due to technological pro-
gress. We have tried to present the content correctly and clearly. If, however,
we have made errors, we would be grateful for information about this.
We are not liable for errors in this description and the resulting consequences.
The UPS system (uninterrupted power supply system) is intended to protect
sensitive, electrical systems such as computers, work stations, electronic cash
registers, critical instruments for operation, telecommunication systems, proc-
ess controls, etc. against interruptions that can occur due to poor power quality
or mains failures. Sensitive systems of this kind require complete protection
against electrical disturbances. These may involve external disturbances (such
as thunderstorms, operational disturbances) or disturbances from adjacent de-
vices (such as engines, air conditioners, processing machines, welding equip-
ment, etc.).
The mains disturbances can be summarised as follows:
–
quick and slow mains voltage peaks, fluctuations;
–
mains failure;
–
quick and slow frequency peaks, fluctuations;
–
mains interference or transients
The UPS system monitors the aforementioned mains parameters and protects
the connected loads by taking appropriate countermeasures (e.g. switching to
support operation in the event of temporary over- or under-voltage in the mains
in order to protect the end devices).
The device can be modified with ease. You have the option of installing the
UPS upright using the feet or alternatively it can be installed horizontally in a
19" rack.
