ABB IRC5 Compact

• The best connection is one in which the shielding is extended up to and
makes a solid 360° connection (shown below) with the ground plane or
chassis.
Shielding example
The below example shows the shielding of a d-type connector:
xx1700001320
A A dimpled connector body makes multiple bonds to the mating connector
body all around its periphery, 360° bonding.
B Metal, or metallized, back shell makes 360° bond to the connector body.
C The cable shield is exposed and 360° clamped to the back shell. A tight fit
is a must.
Many other 360° bonding methods and types of 360° shielded connectors are also
acceptable.
Shield pigtail termination
Shield pigtail termination, as shown below, shall be avoided. If a pigtail connection
cannot be avoided, make it as short as possible.

Ground and screen connections
The task of the grounding system is twofold - protective and functional. The primary
task is to serve as protective earth (PE) for personal and equipment safety. The
secondary task is to serve as a return path for common mode current.
