ELECTRICAL CONNECTION
Each appliance is accompanied by a complete connection and
wiring diagram. This contains full details of the technical speci-
fications (electrical rating, voltage, amperage etc.).
Check and ensure that the mains voltage agrees with the
voltage given on the specification plate.
Please note:
•
The corresponding arrangements must be made on-site for
the earthing connection and fuse protection for the
appliances.
•
The appliance must be connected
zation system with a minimum conductor cross-section of
10 mm². The correspondingly marked terminal stud must
be used for this purpose. When set up in block configura-
tion, all appliances must be interconnected as potential
equalization.
•
The appliance is designed for connection to fixed lines. If
the appliance is fitted directly to a masonry plinth without
an appliance plinth, the supply must be located at the pres-
cribed place. The protecting tube may not protrude from
the plinth. If a CNS base is used, the protecting tube may
not protrude more than 10 cm from the floor.
•
After installation, the shock-hazard protection for live and
functionally insulated parts must be secured.
•
An isolating device working on all poles and with a mini-
mum contact opening of 3 mm must be provided on site.
•
When faulty-current circuit breakers are planned, ones for
a rated tripping current of 30 mA are to be used.
•
When using a residual current-operated circuit-breaker (in
the case of an existing circuit-breaker and for new installa-
tions) only a pulse-current sensitive RCCB may be connec-
ted in series in conjunction with this appliance.

SUPPLY TERMINALS
A = Mains connection
G = Appliance outputs
Fig.9 Supply terminals
Power is taken from a ready-installed electric cable which
protrudes 1.5 m from the floor or the wall.
The supply terminals for the appliance are located behind the
front right-hand cover (B). In order to connect the appliance,
the front panel must be removed (siehe Kapitel 2.1).
Power cable connection as per the electrical diagram.
The terminal screws on the range frame are marked as fol-
lows:
Earth conductor
Potential equalization
Additional terminals for power optimizing systems (EO/SI) or
potential-free contacts (PK) for the external monitoring of the
appliance are available as options. The connections are made
as per the electrical diagram.

INSTALLATION INSTRUCTIONS
4.2
The appliance is to be connected to a potential equalization
system with a minimum conductor cross-section of 10 mm
Use the appropriately marked terminal studs for this purpose
(EN 60 335). The connection consists of an M6 threaded bolt
and is located on the frame of the appliance.

4.3
The potential-free contact of an appliance is independent of
the energy optimisation (EO). It is required to display on an
external switchboard whether the appliance is switched on.
The terminals are labelled 21 to 29.
4.4
The purpose of the power monitoring devices is to avoid the
occurrence of current load peaks when the appliances are
simultaneously under full load.
The following methods are used:
•
•
4.4.1
Power monitoring devices require the following information
from all appliances:
This information is supplied to the monitoring equipment via 4
different lines.
Line A
Line B
Line C
Line D
For ranges, the power contactors are usually fitted externally,
and internally for kettles and pans. For most appliances the
internal wiring for a power-monitoring system can be fitted as
an option.
CONNECTION TO THE POTENTIAL EQUALIZA-
TION SYSTEM
POTENTIAL-FREE CONTACT (PC)
POWER OPTIMIZATION SYSTEMS (EO/SI)
The appliances are connected to a maximum mains cur-
rent monitoring device which, according to the settings
switches off individual devices or stages.
Current peaks are eliminated without any noticeable influ-
ence on cooking processes. On the basis of a continuous
comparison of the actual current consumption of the entire
establishment with a predetermined maximum current limit,
appliances are switched on and off for very short times in
accordance with the program data specific to the
appliances.
WIRING
- Position of the ON-OFF switch
- Operating status of thermostats, electronic controllers
etc.
If an appliance has several controllers, each circuit is
allocated its own control circuit.
signals the switching status (power switch on or
off) of the appliance (voltage 24÷230V) and is
connected to the secondary side of the power
switch.

different voltages.
