2.1 Appropriate Usage
The Automatic Switch Box is a component of a Sunny Backup system M. In case of a grid failure, the
Automatic Switch Box will disconnect the PV system and the loads from the public grid and connect
them to the Sunny Backup. The optional generator is also integrated into the stand-alone grid in the
Automatic Switch Box in case of a grid failure.
Connection requirements
The Sunny Backup system is only certified for TN grids and may not be installed in TT grids.
Principle of an Automatic Switch Box in a Sunny Backup System
The Automatic Switch Box may only be operated in combination with a Sunny Backup. The Sunny
Backup evaluates the data collected by the Automatic Switch Box and coordinates all switching
operations.
The maximum connection power of the individual outgoing lines (e.g. maximum AC PV power to be
connected: 5.7 kW) in the Automatic Switch Box may not be exceeded.
Do not use the Automatic Switch Box for purposes other than those described here. Alternative uses,
modifications, as well as installing components not recommended or sold by SMA may void the
warranty and any applicable interconnection agreements.

5.2 Connecting Loads
The cables of the loads are led through fuse elements in the Automatic Switch Box. The fuses are
necessary in order to protect the output cable from overload in stand-alone grid operation. Note that
in stand-alone operation, both the Sunny Backup as well as the PV system can power the loads, and
the upstream fuse on the grid side has no effect in this situation. Determine the required fuse size
according to layout type of the cable and installation conditions, and install appropriate fuse plugs.
The maximum fuse plugs D02 with a nominal current of 35 A which may be used are included in the
scope of delivery.
DANGER!
Risk of death from feedback of the Sunny Backup system into the public grid.
In case of backup, feedback into the public grid can occur through the backup phase and
the 3-phase loads.
Feeding of the P V system and pot entially from the diesel generator only occurs at phase L1
in case of grid failure.
• When connecting 3-phase loads whose coils or resistors are switched in a triangle,
always connect all three phases to the Automatic Switch Box.
Selectivity of thermal fuses
In unfavorable constellations (e.g. the same fuse value twice in a row), it may happen that
it is not possible to select whether to install the thermal fuses as upstream or downstream
fuses. This is unavoidable due to the complexity of the Sunny Backup system with several
feeding sources.
Cable end sleeves
When using fine-wired cables, use cable end sleeves as well.
This only applies to cables connected to the "F5 Backup Loads" fuse element.
Cable Requirements
The cable type and laying method must be suitable for the application and use location.

SMA Solar Technology AG Electrical Connection
Sizing the Thermal Fuse
Load disconnection unit
Use only line circuit breakers as load disconnection units!
A screw type fuse element, e.g. D system (Diazed) or D0 system (Neozed) is not a load
disconnection device, and thus may not be used as a load disconnection unit.
Upon disconnection under load, the screw type fuse element of the Automatic Switch Box
may be destroyed, or its functionality may be inhibited by contact burning. It only acts as
cable protection.
In the table, select the condition applying to you and observe the corresponding recommendation by
SMA Solar Technology.
Condition Recommendation
The rating of the back-up fuse in the
distribution is equal to the nominal
current of the Automatic Switch Box
during grid operation (35 A).
The rating of the back-up fuse in the
distribution is lower than the nominal
current of the Automatic Switch Box
during grid operation (35 A).
The rating of the back-up fuse in the
distribution is higher than the nominal
current of the Automatic Switch Box
(35 A).
• Use a fuse with a nominal c urrent of 35 A in th e fuse
element "F5 Backup Loads" in the Automatic Switch
Box.
• Install a fuse with the same nominal current as in the
distribution into the "F5 Backup Loads" fuse element
in the Automatic Switch Box.
• Set the maximum grid current through the Sunny
Backup with the parameter 232.02 GdCurNom to
the value of the rating of the back-up fuse.
• According to the installation, install as fuse not
exceeding 35 A into the fuse element "F5 Backup
Loads" in the Automatic Switch Box.
• Install a fuse with max. 35 A in the distribution.

Connection Procedure
1. Select the suitable opening for the loads cable and poke a hole in it with a pointy device.
The cable has to be tightly enclosed by the cable gland after insertion.
2. Pull the loads cable through the cable opening into the inside of the Automatic Switch Box.
3. Connect PE and N to the "X3/Backup Loads" connection terminal according to the label. The
second connection terminal "N" is not assigned.
4. Connect L1 and possibly (in case of 3-phase loads) L2 and L3 according to the labels to the
"F5 Backup Loads" fuse elements.
☑ The loads are connected.

5.3 Connecting the PV System
Cable Protection
The Automatic Switch Box S is not intended to serve as a distri butor box or fuse box for the
PV system. For safety and disconnection, a line circuit breaker must be installed between
Automatic Switch Box and PV system. Be sure to observe all standards applicable to the
installation and site.
Connection of additional energy sources
Only those energy sources may be connected to the Automatic Switch Box for which the
corresponding tariff of the feed-in counter is valid. Instead of the PV system, you can also
connect other energy sources (e.g. small wind energy systems) to the Automatic Switch
Box. One prerequisite is the fact that a corresponding feed-in meter is connected to the
Automatic Switch Box.
Si nce onl y on e fe ed- in m ete r ma y be con nected to the Aut oma tic Switc h bo x, o nly one tar iff
is specified. The connection of a PV system and a small wind energy system (energy
sources mix) is not possible.
Cable Requirements
The cable type and laying method must be suitable for the application and use location. The cable
after the upstream fuse on the grid side must be selected.
For Sunny Backup systems with a generator connection, attention must also be paid to the fuse
protection of the generator feed-in. If the generator feed-in at the "X6/Generator" connection terminal
has a greater fuse protection than the supply cable from the feed-in meter
(upstream of "X5/PV Meter"), then the output cable from the PV System (X4/PV system) must be
implemented with this higher fuse value.

DANGER!
Risk of lethal electric shock!
Residual current devices (RCD) between grid and Automatic Switch Box would lose their
protective function due to the Backup System.
• Do not connect a residual current device (RCD) between grid and Automatic Switch
Box.
• Do connect a residual current device (RCD) between loads and Automatic Switch
Box.
DANGER!
Risk of death from feedback of the Sunny Backup system into the public grid.
In case of backup, feedback into the public grid can occur through the backup phase and
the 3-phase loads.

• When connecting 3-phase loads whose coils or resistors are switched in a triangle,
always connect all three phases to the Automatic Switch Box.
DANGER!
Risk of lethal electric shock!
The Sunny Backup system requires a grounded neutral conductor in order to form a TN
grid in case of grid failure and be able to apply the corresponding protective measures.
• Do not install any switching elements in the grounded neutral conductor to the
