Refer to the tables given below for connection of the power supplies and signals present on the HARTING
connectors (X3x).
Conductors
For connection, use COMAU cable code 00420859 with the following characteristics:
Composition
40 x 18 AWG black conductors
8 x 14 AWG black conductors
3 x 20 AWG twisted pairs individually shielded
Operating voltage
300/550 V
Test voltage
1500 V
Operating temperature
80 °C
Outside diameter
29 mm max.
Outer sheath
RAL 7035 grey PVC
Shielding
85% cover-copper plait
It should be remembered that for installations in Italy the conductors must comply with CEI 20-22 standards
second part; if the COMAU cable is not used, conductors with equivalent electrical characteristics and com
-
plying with UL 758 VW1 standards must be used.
Failure to comply with the above instructions results in non-compliance with the UL approval
standard of the module to which the cable is connected.
The maximum permissible distances for connections are given in the following figure.
The connection cables of connectors X3x leading from the remote unit must be shielded and
the shielding must be earthed appropriately.
