5.1.2 Minimum Workspace Requirements
When installing the inverter, appropriate clearances to stationary objects and neighboring inverters
must be observed. Minimum passage widths, escape routes, and minimum clearances for optimal
ventilation are to be guaranteed. The corresponding specifications are contained in Appendix C.
Refer to the national applicable standards for installing and connecting the Sunny Central inverter. In
Germany, the requirements for passage widths and escape routes in electrical operating sites and the
installation of high voltage systems of up to 1000 V are regulated by DIN VDE 0100 part 729,
part 731.
The minimum clearances and passage widths to be maintained along with the corresponding
dimensions are contained in Appendix C.
5.1.3 Inverter Protection Rating / EMC / Sound Levels
The outdoor version of the Sunny Central SC 100 is suitable for outdoor installation according to the
IP44 protection rating. The control area is enclosed from the power area and has IP54 protection
rating. The indoor version of the Sunny Central SC 100 is suitable for installation in a station located
in a dry, dust-reduced environment according to protection rating IP21. With regard to the EMC
emissions and the noise level, the inverter is conceived for setup in an industrial environment or for
outdoor installation.
The technical diagrams with the dimensions are contained in the Sunny Central installation
requirements.
WARNING!
With fully opened cabinet doors, a minimum passage width of 500 mm (escape route)
must be maintained.
To maintain the minimum passageway requirements, the cabinet doors in an inverter
system with two rows of opposing cabinets may only be opened on one side at a time.
