Electrical Connection
ATTENTION:
Even with switched off mains there is a dangerous high battery voltage inside the UPS. All installations
and connections may only be carried out by qualified technicians. The technician must familiarize himself
with the special features of this UPS by carefully reading and understanding this manual.
Please observe the special notices for connections of a parallel-system.
The work for electrical connection is a part of an electrician who installs the whole electric installation. It is not part of the
UPS manufacturer. For this reason, the following recommendations are only an indication, as the UPS manufacturer is
not responsible for the electrical installation.
In any case we recommend carrying out the installation and the electrical connections to the UPS in accordance to the
local rules and standards.
During the electrical installation make sure a right phase rotation at the three-phase input terminals of the UPS.
In case of strong electromagnetic fields emission it is recommended to use a shielded cable between UPS and the load.
In accordance to EN 62040-1 a mains-feed-back protection has to be provided for the UPS, preventing a current flow
from the output of the UPS back into mains at a single fault of the system. Therefore both the lines for the main input
and the bypass lines have to be fed via a contactor, which opens in case of a mains blackout.
For improving the quality of connection of the UPS flexible cables are recommended. A cable clamp must be provided
by the end-user directly at the structure of the frame or right below the UPS cabinet.
The wire diameters given in technical data refer to a distance of 50m between load and UPS. These values are recom-
mendations only. They have to be recalculated particularly considering the actual environment conditions!
At larger distances the permissible voltage drop, the environmental temperature and the cable grounding have to be
dimensioned according to VDE or local rules. Local rules for the protection ground-wires have to be considered.
The suitable diameters of cables and the sizes of the fuses are to be designed with regard to the environmental tempe r-
ature, the cable grouping and length of cables according to the local rules and according to VDE.
The terminals are positioned at the lower part of the UPS and they can be accessed by opening the front door.
