Requirements for assembly
The assembly must comply with the applicable regulations,
standards, directives and laws where they apply to the subject
of the contract.
Work on the electrical system (electrical connection, cable duct
or sockets) may only be carried out by a qualied electrician.
Note
To avoid the assembly work being delayed or even stopped, the
installation of the appliances should be carefully planned in ad-
vance. It must be ensured that all the requirements are satised.
Requirements for the place of installation
Ensure that the place of installation for assembling the appli-
ances is suitable and properly prepared.
– Any existing old appliances must be removed and disposed
of in an environmentally friendly manner.
– The place of installation must be free of dirt and moisture.
– The evenness of the oor surface must comply with the
usual limit values for evenness deviations set out in DIN
18202.
– The ambient temperature must correspond to the climate
rating. The climate rating applicable to your appliance is
shown in the operating instructions.
– Any display unit above the appliance must be straight and
perpendicular, and must not contain any goods.
– Any positioning rails must be installed to meet the plinth foot
spacings of the appliances.
– If a collision guard or positioning rails (accessories) are
installed, approval must be obtained from a qualied body
to drill holes in the oor. It must be ensured that no cables or
pipes (e.g. underoor heating) in the oor are damaged.
Ventilation
Ensure that the following cross-sections for ventilating the
appliances are maintained in the supply air area on the rear of
the appliance:
– 1.8m: > 550cm²
– 2.1m: > 600cm²
– 2.5m: > 700cm²
If ram protection is installed, the same cross sections must be
ensured for the exhaust air.
In combination with surface-mounted appliances with
downward-directed exhaust air (heat), appropriate partitioning
must be provided against this.
Requirements for the electrical connection
– We recommend that separate circuits are installed for the
lighting and chest refrigeration units. The sockets must be
clearly distinguishable.
– Two sockets must be prepared for each appliance for these
two circuits. The sockets must be permanently xed and
clearly labelled.
– Each appliance must be protected by its own fuse.
– A separate fuse must be provided for the lighting
IMPORTANT
Do not connect the appliance
using an extension cable or
extension socket.
Requirements for a remote data transmission
connection
– A connection from the appliance blocks to the gateway
location must be established on site using suitable sockets
and cables (CAT5 or higher) with a bus topology.
– The appliances are networked using one or more coupling
modules depending on the system environment, see "Bus
connection", page 4.
Bus connection
Up to 120 appliances can be networked and integrated into the
in-house system using one or more coupling modules.
Note
The alarm priority with CAN connectivity is limited as standard
to a maximum of 2 when the appliance is delivered. This means
that the forwarding of the alarm is restricted when the shop is
closed. The setting can be changed if necessary by the gateway
manufacturer. The list of alarm scenarios is included in the ser-
vice documentation.
A coupling module is required for transmitting the CAN bus
protocol.
Depending on the system environment and the number of ap-
pliances, we recommend that you use the following coupling
modules (made by Wurm):
5
EN
– C2C-EB-UNI-R
ASCII protocol
1 coupling module for an arbitrary number of appliances
– C2C-MOD-S-MAN
RS485 standard interface (Modbus RTU) slave
with 1 coupling module for up to 20 appliances
Each appliance has two CAN bus ports for networking the appli-
ances, see "Fitting the cables", page 10.
Addressing
Free addresses from the in-house system must be used to ad-
dress the bus with one- to three-gure numbers (1-999) being
allocated for this purpose.
The addresses are entered individually on each appliance, see
"Assigning addresses to the appliances", page 19.
