9. ELECTRIC CONNECTION
Electric connection must be carried out by
qualified technicians and must comply with local
and national rules in force. Check if the supply
data corresponds to the data written on the
machine plate.
To connect the machine use a H05 VV – F cable
or superior, it must be correctly dimensioned
following the data label.
Install before the machine a omnipolar
disconnecting device (i.e.: a circuit breaker) which
need to have a contact opening that allows the
complete disconnection in case one of the
conditions of the over tension III category is
verified. This device must comply with the subject
regulation in force.
Check the main switch, it must be in position “0”.
Open the electric supply door. Open the electric
supply door.
Pass the electric supply cable through the cable
holder supplied with the machine. The cable must
be correctly dimensioned (check the following
table).
Electric supply cable connection must be done on a
series of marked terminal.
Following the kind of heating, which is indicated
on the serial number plate, connect the cable to
the terminals, as indicated:
: ground, colour: yellow/green
L1, L2, L3: phase, colour: brown
N: neutral, colour: blue
In case of installation or replacement of the
supplying cable, the ground cable must be at least
5cm longer than the other cables.
The electric diagram is contained in an envelope,
near the electric board.
ATTENTION!
Check the fan rotation direction: it must rotate in
the direction which allows the exhaust air
discharge; it means that the fan motor must
rotated in the direction indicated by the arrow
marked on the motor cover.
Check that the phases are connected in the
correct sequence.
The machine must be connected to an efficient
ground system: the supplier is not responsible in
case this connection is not operated in
compliance with the subject rules in force.
Before to do any maintenance cut the electricity
supply to the machine: for maintenance refer to
the machine electric diagram, which is inside the
machine; anyway, it can be retrieved in any
moment in the manufacturer web site.
The minimum section for the electric cable are
indicated in the attached technical data sheet and
are expressed in mm
2
.
ATTENTION!
The technical data minimum sections can change
according to the connection length. In case the
cable is longer than 5 meters, the cable diameter
must be proportionally increased.
ATTENTION!
The machine connection must always be made
respecting the data written in the serial number
plate (power, supply tension, frequency).
For voltage different from the one provided, ask
for more information to the manufacturer.
ATTENTION!
For machine equipped with drum or fan speed
control, it means for machine equipped with
inverter, a protection by RCD kind B device must
be provided (sensible to the current medium
value).
ATTENTION!
In case the machine is equipped with a supply
cable, and the cable is damaged, it must be
replaced by the manufacturer or by the authorized
technical service;, anyway only qualified
personnel can service the machine, in order to
prevent any risk.
10. GAS CONNECTION
If the machine is gas heated, the necessary
connection with distribution system must be
made: check the machine serial number plate
data, especially supply gas pressure.
