Important notes relating to the connections
•
For the power supply line input use an unshielded cable with suitable
section equipped with ground conductor connected to the dedicated
input.
•
For the motor connection use a shielded cable with suitable section
equipped with ground conductor connected to the dedicated input.
•
The shield of the motor cable must always be connected at both ends ( at
the product end on the structure by means of the screw provided and at
the other end on the motor casing).
•
The ground wire of the motor cable must always be connected at both
ends ( at the product end on the dedicated input and at the other end on
the motor casing).
•
For the signal connections use a shielded cable and connect the shield of
the signal cable only at the product end using the fixing screw on the
structure. Only in the case of particular applications with several
products, where the length of the signal cable exceeds 5 m, can the
shielded be connected at both ends, preferably using a separate
connection (see following note)
•
Keep the connections of the signal shields and ground wires separate
from the power ones: next make a single connection towards the plant
ground wire, according to the star connection principle.
•
The shield must have a coverage of at least 80% of the cable’s length.
•
Do not use the converter as a connection or ground point for other
devices.
