Selecting the cross-section of the power supply cables
With the 24V (DC) power supply, it is necessary to check the cross-section of the cable,
which should be calculated based on the length of the cable itself. The table below
specifies the maximum length of the cables for connection of a motor.
Cable section
Max cable length
4,00 mm²
~ 270 m
2,50 mm²
~ 170 m
1,50 mm²
~ 100 m
0,75 mm²
~ 50 m
0,50 mm²
~ 35 m
8. Electrical connection
The machines are equipped with a power supply cable constructed in compliance with
safety standards and restrictions on radio-frequency interference.
The power supply cable - with conductors having a cross-section of 0.5 mm² - must
be wired to a special connector as shown in the diagram below, in the following
sequence:
1
