NOTICE:
Make sure that there are no bits of wire or
sheathing or other foreign materials in the control
panel when making the electrical connections.
Take all due care to avoid damaging the internal
parts when removing anything inside.

Mains power supply connection
NOTICE:
The cross-section of the main power supply cable
is suitable for the maximum current consumption
of the electric motor and also considering the
maximum voltage drop (≤4%).
Installation and replacement of the main power
supply cable
Refer
to
1.
Ensure that the control panel
figures 5,
is isolated from the power
6,
7
and
supply and cannot be ener-
8.
gised.
2.
Open the front covers (1) and
(3), and turn the main switch
(2) OFF.
3.
Unfasten
M4x25 and open the REAR
cover (see Figure 6).
4.
Insert the power cables in the
relevant cable gland (1), Fig-
ure 5.
5.
First connect the ground ca-
ble to the relevant terminal
and then connect the other
cables. It is good practice for
the ground cable to be longer
than the other cables, Fig-
ures
6.
Check that all the cables are
secured, close the REAR
cover and fasten the screws
if no other cables have been
connected.
NOTICE:
If some models have a power supply cable with a
cross-section of 4G2.5mm2, this is only for the
internal production test. Check the voltage drop
(≤4%) and replace it with a cable of an appropri-
ate cross-section.
4.3.3
Motor power cable connection
If the power cable of the motors needs to be added
or replaced, fit a new one of a cross-section suited to
the maximum current consumption of the electric
motor and taking into account also the maximum
voltage drop (≤4%).
Refer
1.
Make sure that the control panel
is isolated from the power supply
to fig-
and cannot be energised.
ures 5,
2.
Open the front covers (1) and (3),
6, 7, 8.
and turn the main switch (2)
OFF.
3.
Unfasten the 4 screws M4x25
and open the REAR cover (see
Figure 6).
4.
Insert the motor power cables in
the relevant cable glands (3) (5),
the
4
screws
7
and 8.
