WARNING!
An electric shock can be fatal. Make sure that both the input side and output side of the
device are de-energised before opening the device. Wait for the capacitors to discharge (5
minutes).
Controlling the in-
verter via De-
mand Response
Modes (DRM)
Notes regarding
dummy devices
A dummy device is not suitable for connecting operationally to a photovoltaic system, and
must only ever be used for demonstration purposes.
IMPORTANT! Never connect DC cables to the DC connection sockets on a dummy de-
vice.
The connection of de-energised cables or sections of cable for demonstration purposes is
permissible.
A dummy device can be recognised by its device rating plate:
Example: Device rating plate of a dummy device
String fuses
Dangerous electrical voltage
Wait for the capacitors to discharge.
IMPORTANT! To control the inverter via DRM, a Fronius DRM interface (item number
4,240,005) is required in the inverter.
Installation is described in the installation instructions for the Fronius DRM interface. The
installation instructions for the Fronius DRM interface are available at the following link on
the Fronius homepage:

WARNING! An electric shock can be fatal. Danger from voltage at the fuse hold-
ers. The fuse holders are live when a voltage is present on the DC connection of
the inverter, even when the DC switch is switched off. Make sure that the DC side
is de-energised before carrying out any work on the inverter's fuse holders.
