3. UPS Device Description

This manual shall provide basic information about one-phase line-interactive

UPS-systems, like the mode of operation, utilization of the different functions

and what to do in case of malfunctions.

In addition, this manual contains instructions for the proper transportation and

storage, as well as for the handling and installation of the UPS-equipment.

The planning guidelines in this manual refer only to the specific requirements of

UPS-systems. National and regional regulations for electrical installations have

to be adhered to, when installing the system.

The content of this device description may change due to technological pro-

gress. We have tried to present the content correctly and clearly. In case of any

errors, we are grateful for advice and suggestions.

We do not assume any liability for any errors in this manual or any conse-

quences resulting thereof.

The UPS-system (uninterruptible power supply) is designed to protect sensitive

electronic equipment like computers, work stations, electronic cash registers,

operations critical instruments, telecommunication systems, process control-

lers, etc. from interferences that can result from poor power quality or mains

failures. Sensitive equipment of this sort needs comprehensive protection from

all electrical interference. These may either be external interferences (like e.g.

lightning, disruption of operations) or interferences from other devices in its vi-

cinity (e.g. engines, air-conditioning, processing machines, welding facilities, or

the like).

Power interferences can be summarized as follows:

– rapid or slow voltage peaks or fluctuations;

– mains failure;

– rapid or slow frequency peaks or fluctuations;

– power overlaps or transients

The UPS-system monitors the above mentioned grid parameters and protects

all connected appliances through appropriate countermeasures (e. g. switching

to bypass mode when temporary over- or under-voltage of the grid is detected,

to protect the end device).
