The operator must provide the following infrastructure
in fully operational state before delivery and installa-
tion of the appliances and bears the responsibility for
these systems and interfaces to be connected:
–
Power supply
–
Wastewater drainage - defrosting water drain con-
nection
–
Overall market control
–
DFU access for remote maintenance (optional)
For interface technical data, see → Technical data
Technical modifications to the appliance only in agree-
ment and after approval of the manufacturer. Do not
cover the temperature display, safety notes, or the rat-
ing plate (see → Rating plate and serial number).

Communication interface

The appliance features a communication interface
(bus connection). This interface can be used to con-
nect the appliance to a monitoring system.
Several appliances can be interconnected via the
communication interface. Depending on the appliance
type and configuration, it may be necessary to inter-
connect several appliances.
NOTICE
Material and property damage due to faulty
communication between appliances and with
the monitoring system.
Never break an existing bus connection.
The signal to activate daytime/night-time operation is
transmitted to the appliance via the communication in-
terface.
WARNING
Appliance tipping hazard.
Persons may become trapped.
▪ Remove the transport frames only when in
the stable and final installation position.
▪ Use an anti-tilt device.
▪ The device may only be installed and disman-
tled with an anti-tilt device.
▪ Do not remove the anti-tilt device until there is
no more risk of tilting. Fuse protection is pro-
vided, for example, by a wall or opposite de-
vice for island installation. Anti-tilt device is
supplied as an accessory by the AHT installa-
tion service.
▪ Do not remove the additional device-specific
anti-tilt device after installation.
▪ Observe the separate assembly instructions.
▪ If you have any questions, contact the mainte-
