Intended Use

The Grid-Connect-Box is an automatic transfer switch which enables the safe operation of the utility grid and an
electricity generator as energy sources of an SMA multicluster-system.
The technical connection requirements of the grid operator and the local standards and directives specify if the
multicluster system, in the event of grid failure, disconnects from the utility grid at all poles or only the line conductors.
The Grid-Connect-Box is always delivered with all-pole disconnection. If all-pole disconnection is not permitted, the
Grid-Connect-Box all-pole disconnection function must be deactivated (see Section 6.2, page 18).
If the Grid-Connect-Box is used with all-pole disconnection, the utility grid must be either a TN-S, TN-C-S or TT system. If
the Grid-Connect-Box is used without all-pole disconnection, the utility grid must be a TN-C-S system (for grounding in
the multicluster system, see the Multicluster-Box operating manual).
Do not exceed the maximum AC connection power of the Grid-Connect-Box. Cables with copper conductors must be
used for the installation.
The Grid-Connect-Box may only be commissioned in conjunction with the Multicluster-Box.
In terms of interference immunity, the product is suitable for EMC environment A, and in terms of EMC emissions, it is
suitable for EMC environment B (as per IEC 61439-1:2011).
The product is designed for indoor use only.
Only operate the product at temperatures between −-25°C and +60°C.
The Grid-Connect-Box is designed for use at altitudes of up to 3000 m above Mean Sea Level. If you would like to use
the Grid-Connect-Box at altitudes above 3000 m, contact Service (see Section 13, page 35).
