4.1.4 Electrical Operating Room
For the installation and connection of the Sunny Central central inverters, observe DIN VDE 0100,
part 729, part 731. The requirements for the electrical operating room for the installation of high
voltage systems up to 1000 V as well as the requirements for passageways and escape routes are
included here.
MV Stations
The inverters of the HE series are usually installed in a concrete compact station, generally opposite
as a "left" system and "right system". The installation has to be carried out in accordance with the VDE
guidelines for a closed electrical operating room. In the figure below, a left-hand and right-hand
system is shown.
The AC cabinets should in any case be located at the partition wall to the transformer room in order
to implement the AC power cabling to the transformer with short cable routes.
Minimum passageway in electrical operating rooms
Observe the following points for a minimum passageway:
• With fully opened cabinet doors, a minimum passage width of 500 mm
(escape route) must be maintained, see DIN VDE 0100 part 729, part 731.
• To maintain the minimum passageway requirements, the cabinet doors in an inverter
system with two rows of opposing cabinets (e.g. installation in a station building) may
only be opened on one side at a time.
