4.3.2
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
figures 5,
6, 7 and
8.
1. Ensure that the control panel is
isolated from the power supply
and cannot be energised.
2. Open the front covers (1) and
(3), and turn the main switch
(2) OFF.
3.
Unfasten the 4 screws
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
7 and 8.
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 elec-
tric motor and taking into account also the maxi-
mum voltage drop (≤4%).
Refer
to fig-
ures
5,
6, 7, 8.
1. Make sure that the control panel
is isolated from the power supply
and cannot be energised.
2. Open the front covers (1) and (3),
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),
Figure
5.
5. First connect the ground cable to
the relevant terminal and then
connect the other cables. It is
good practice for the ground ca-
ble to be longer than the other
cables, Figures
7 and 8.
6. Check that all the cables are
secured, close the REAR cover
and fasten the screws if no other
cables have been connected.
4.3.4
I/O connections
The terminals must be chosen according to the
application and the type of sensor used (figures
7
and 9). For application, refer to figures 11 to 64
Refer
to fig-
ures
5,
6, 7
and
9.
1. Make sure that the control panel
is isolated from the power supply
and cannot be energised.
2. Open the front covers (1) and (3),
and turn the main switch (2) OFF.
3.
Unfasten the 4 screws M4x25
and open the REAR cover (see
Figure
6).
4.
Insert the cables in the relevant
cable glands, Figure 5, section 4.5.
5. Connect the cable to the relevant
terminals, Figures
7 and 9.
6. Check that all the cables are
secured, close the REAR cover
and fasten the screws if no other
cables have been connected.
4.3.5
Replacement of Fuse F1 or F2
If Fuse F1 or F2 needs to be replaced because it is
defective, replace it with one of the correct charac-
teristics.
Alarm A01 indicates that Fuse F1 is defective.
Alarm A02 indicates that Fuse F2 is defective.
Refer to
figures 5,
6, 7 and
1. Make sure that the control panel
is isolated from the power supply
and cannot be energised.
2. Open the front covers (1) and (3),
