Step 4: Make the connections
To operate the machine requires:
-
An electrical connection.
-
A water connection and drainage.
-
A connection to the aeraulic circuit (air ducts).
Electrical connections
As to the
power supply,
an
electrical cable
must be connected to the machine:
single phase + n earth
(size 01 and 02).
three phase + earth
(size from 03 to 10);
(N.B.: The power supply of any electric batteries is separate from that of the unit and is always three-phase).
The cable must have a
section adequate to the electrical
absorption of the machine and the current
regulations. The total electric draw is shown on the machine's tag.
Always refer to the wiring diagram that is specific to the machine that you bought
(it was
shipped with the unit). If it is not on the machine or has been lost, contact the salesperson of ref-
erence who will send a copy (specify the machine's serial number).
Before connecting the machine make sure that:
• The voltage and frequency of the power supply correspond to the parameters of the machine.
• The electrical system being connected has sufficient capacity to supply the nominal electric power of
the machine to be installed and meets current regulations.
The electrical connection must be:
• Performed by qualified personnel after cutting off the facility's power supply.
• Performed in a fixed and permanent manner, without intermediate splices, in accordance with the
regulations of the country of installation.
• The power supply is sufficient for the machine (see technical specifications).
• Includes a functioning grounded plug; for multiple units it is necessary to combine them all with metal
ties.
• Preferably situated in a dedicated room,
locked
and protected from atmospheric agents. If there is also
a key switch, the key must be removed when cutting the power supply and returned to its position
only after finishing service operations.
• Controlled by a
multipolar switch
with switching capacity equal to 60A suitable for the machine ab-
sorption.
During installation and maintenance, make sure that
no other person
besides the one who is
working has access to the electrical cabinets or switches.
The actual supply voltage of the user devices
must not deviate more than 10%
from the expected
nominal voltage. Higher voltage differences cause damage to users and to the electrical system, mal-
functioning of fans, noise. It is therefore essential to check the alignment of the actual voltage values
with the nominal values.
The Manufacturer is not responsible for connections made in a manner that does not comply
with regulations, with the specifications of this manual, and in the event of tampering with any
electrical component of the machine.
