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.
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.
