Electrical connection
Important!
For reasons of safety and the validity of the war-
ranty, all electrical work must be carried out by a
qualified electrician.
The oven must be connected via an external main
swich with min. 3mm gap.e of at least 3 mm for each
power supply cable.
Tip! Ideally, the oven should be connected with one
power supply cable per oven chamber (or deck). This
gives the following benefits:
• It enables a much lower main fuse rating, giving a
lower overall electrical cost.
• If a fuse does blow or trip, only part of the oven is
affected, thus reducing the impact on productivity.
Fuse protection needs
• In the case of 1 power supply cable per deck, see
the table below for the correct fuse rating per deck
relative to the supply voltage.
• In the case of 1 power supply cable per oven, see
the oven rating plate and the attached electrical
wiring diagram before calculating the fuse rating.
The digit 0 in the model codes below is replaced by 1,
2 or 3 on the oven rating plate according to the number
of decks.

After reading all above information, follow instructions
below for correct electrical connection.
1. Make sure electrical supply corresponds with that
specified on the oven rating plate.
2. Remove the screws (4 pcs) that secures the right-
hand side panel, and take off the panel.
3. Feed the power supply cable(s) (provided by
customer) through the access holes (see fig. 2) on
the right-hand back of the oven and pull the cable to
the field terminal block (see fig. 3).
4. Following the appropriate electrical wiring diagram
confirming to the oven rating plate, connect the
power supply leads to the field terminal block (see
fig. 3).
5. Make sure all connections are tight, then replace the
right-hand side panel.
The earth potential equalizer screw has to be installed.
The earth potential screw is located on the backside
next to the connecting cable.
