N O T E!
The UPS should be attached to the mains supply and switched on at the latest 4
weeks after receipt in order to prevent the battery discharging itself.
P L E A S E N O T E
!
In order to exclude the possibility of overloading or constant switching over to bypass
due to consumer generated non-sinusoidal current peaks, no devices such as laser
printers, fax machines as well as devices operating with a similar technology should be
connected to the UPS.
In cases where it is essential that such devices be operated then a UPS must be
selected whose capacity can match the maximum possible current peaks.
Devices with power reduction due to half wave power consumption, (e.g. coffee
machines, hair dryers) can lead to immediate destruction of the power-output stage. The
battery is not galvanically isolated from the mains so occurrence of a mains voltage at
the battery terminals is possible! The UPS unit does not have an output transformer and
is therefore not galvanically isolated from the mains!!
P L E A S E N O T E!
The batteries used are just designed for the required backup time to supply
the nominal load of the UPS. Operation of the UPS unit in free running mode
for a longer period of time on battery can damage the batteries. This effect is
due to the nature of the battery since for a longer discharge period the final
discharging voltage is not reached.

General notes regarding the ups devices
The device may only be opened by trained specialists.
The system is to be connected up and earthed according to VDE regulations. Provisions of the local energy
–
supply company must be observed.
The ventilation slits on the front and rear sides must not be covered and a distance from the wall of at least
100 mm
is essential.
The UPS unit is built according to Protection Class
IP 21
and is designed for installation in heated internal
spaces (at 20°C). A lower operating temperature lowers the bridging time.
No devices with a connecting cable in excess of
10 metres
in length should be connected to the UPS. This
measure serves to ensure observance of the EMC standard.
No alterations should be made to the UPS unit. The warranty will expire in cases of inappropriate physical
interventions.

Description of the System
UPS devices of this type are particularly suited for supplying critical power consumers in industry and the
office such as personal computer, computer-controlled devices, PLCs and similar equipment. The output
voltage is sinusoidal. In normal cases the attached consumers are supplied with power from the installed
rectifier and installed inverter from the mains power supply network (online operation). Any disturbances in
the mains such as voltage peaks, voltage drops, harmonic distortions or noises etc. are filtered out. The
installed battery is constantly being charged up by means of a charging rectifier with a charge preservation
charging stage which is gentle on the batteries.
