UNIGATE fieldbus gateway for ProfibusDP V. 4.7
29.4.11
Please note the following points when shielding:
•
Use metal cable clips to secure the shield braiding. The clips must surround the shield over a
large area and must have good contact.
•
Downstream of the entry point of the line into the cabinet, connect the shield to a shielding bus.
Continue the shield as far as the module, but do not connect it again at this point!
Shielded data lines and unshielded power supply lines (< 60 V DC) are routed to and connected
to the module. All cable shields must be earthed at both ends in order for the module to comply
with all required EMC limits.
•
Downstream of the entry point into the switch cabinet, the ProfibusDP cable shield must be
connected to the equipotential bonding strip.
•
You must earth the shielded RS232C connection cable via the shield terminal on the module
using a flexible wire with a cross-section of at least 1.5 mm² which is as short as possible.
•
You must also earth the other end of the cable shield of the RS232C connection cable.
