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.

!
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 meet 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.
1. General notes
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.
2. Description of the System
Power supply devices of the JOVYATLAS POWERMASTER S – series are particularly suited for supplying
important 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.
