4 Introduction
This manual is intended to provide basic information on single-phase online
UPS equipment including their functional principle, application of the various
functions and troubleshooting. In addition, this manual contains information on
transportation and storage as well as handling and installation of the UPS
equipment.
The planning guidelines in this handbook relate only to the specific
requirements for UPS equipment. During installation, the national and local
regulations for electrical installations must be followed without fail.
This equipment description contents may change as a result of technological
developments. We have endeavoured to make these contents as accurate and
clear as possible. However, we would be grateful for information on any errors
which are noted.
We accept no liability for errors in this description and their consequences.
The UPS equipment (Uninterruptible Power Supply) is to protect sensitive
electrical devices such as computers, workstations, electronic points of sale,
mission-critical instruments, telecommunications equipment, process controls,
etc. from faults which may arise as a result of poor power supply quality or
even power failures. Sensitive devices such as these require comprehensive
protection against electrical faults. These may be external faults (e.g. bad
weather, operating faults) or faults caused by neighbouring devices (e.g.
motors, air conditioning units, processing machines, welding equipment, etc.).
The power supply faults can be summarised as follows:
o
Fast and slow voltage spikes and fluctuations;
o
Mains power failure;
o
Fast and slow frequency spikes and fluctuations;
o
Mains heterodyning or transient voltages
The UPS equipment prepares the mains voltage and ensures that the voltage
values at the output to the consumer load remain constant. Faults in the mains
voltage are thus prevented from reaching mission-critical devices and cannot
cause any damage to software and hardware, data loss or operating faults.
