4.4 CONNECTING TO THE ELECTRICITY MAINS
The lift must be connected to the mains electricity supply by the customer.
To connect to the electricity supply, use a 3 core + earth cable with cross section of 2.5 mm2 for the 400V version.
The cable must be completed with a main plug of the type in use in the country where the lift is installed.
The lift is fitted for the mains connection cable to arrive from below, but it can also be received from above.
THREE-PHASE CONNECTION
MONO-PHASE CONNECTION:
Once the passage of the cable has been carried out, it must be
suitably stripped, the ends of the unsheathed wires and provided with
insulating bushings and the appropriate yarns L, N, Pe.
It should be remembered that the presence of the PE marking
machine is expressly provided for by the electrical regulation EN60204
and therefore it is absolutely necessary to provide for its application.
The conductors must be connected as shown in the figure 4a:
The phase conductor L and the neutral N at the terminals of the
differential switch QF, while the PE ground conductor is connected to
the special ground rod.
Connect the cables coming from the motor
on the terminal board in position U and V
WARNING
The manufacturer declines liability for any damages resulting from failure to follow the above instructions,
which may invalidate the warranty.
WARNING
Whenever you change the power source of the machine, always check the direction of rotation of the
motor.
Operator's manual [EN]
Once the passage of the cable has been carried out, it must be suitably
stripped, the ends of the unsheathed wires and provided with insulating
bushings and the appropriate yarns R, S, T, and Pe.
It should be remembered that the presence of the PE marking machine
is expressly provided for by the electrical regulation EN60204 and
therefore it is absolutely necessary to provide for its application.
The conductors must be connected as shown in the figure 4:
The phase conductors R, S, T to the terminals of the QF differential
switch, while the PE ground conductor is connected to the special
ground rod.
The machine operates normally at 400 Volt 50 Hz (Star). The actual
supply voltage is indicated on the identification plate.
The electrical system and the connections are different according to the
supply voltage / frequency and are set up in the factory.
