4 Installation
This section describes the transport options for the Sunny Central and the requirements of the
installation site.
Different transport and installation conditions apply to each Sunny Central. They are available in the
SMA Solar Technology download area.
4.1 Installation site requirements
Floor
The floor must guarantee solid and safe positioning of the Sunny Central. The floor must provide the
load-carrying capacity necessary to cope with the weight of the Sunny Central. Do not install the
Sunny Central on a slope. Level any unevenness in the floor.
Wall Clearances
When installing the Sunny Central, comply with the corresponding wall clearances for minimum
passages, escape routes and ventilation. The "Sunny Central Installation Requirements" (separate
document) contain the respective minimum clearances.
Inverter Protection Rating / EMC / Sound Levels
The Sunny Central is suitable for installation in dry areas with low dust levels. The Sunny Central was
designed for use in industrial environments in terms of the EMC thresholds (EMC = Electromagnetic
Compatibility) and sound levels.
4.2 Electrical Service Room
When installing and connecting the Sunny Central central inverter, observe the requirements for
electrical operating rooms, installing high-voltage current plants up to 1000 V, and the requirements
for passage widths and escape routes.
4.2.1 Minimum Passage Width
Note the following points for the escape routes in electrical service rooms:
• When the switch cabinet door is opened as far as possible, a minimum passage of 500 mm
(escape route) must remain.
• In order to comply with the minimum passage width, if two switch cabinets are installed opposite
one another (e.g. in a station building), only one of the switch cabinets may be opened.
Identifying cabinet units
The Sunny Central consists of 2 switch cabinets. If multiple Sunny Central units are
delivered, only install switch cabinets with the same serial number together.
