2 Installation and commissioning
2.5.2 Connecting cables to the controller
Continued
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.
For further information refer to EN 60204-1 and UL 1740.
Grounding requirements
The controller cabinet ground must come from the mains power supply PE.
For requirements on the marking of the supply ground connection inside the control
cabinet refer to UL 508C. For further details on how grounding systems should be
designed refer to IEC 61000-5-2. For details of cross-sectional area of PE refer to
IEC 60204-1.
Grounding installation
For information on how to install the ground for the IRC5 controller cabinet, see
Connecting power supply to the controller on page
For information on how to install the ground for the manipulator, see the
corresponding product manual.

• The cross-sectional area of each grounding (PE) conductor must be not less
2
than 10 mm copper (AWG7) in the IRC5 controller and in the manipulator.
• The grounding cable color shall be green-yellow.
• The ground for the controller cabinet, robot manipulator and peripheral
devices must be the same, preferably an equipotential ground grid (mesh).
• Ground connection points must have stable inter-metallic bonding, like screw
fixation. Paint, dirt, rust, and other insulating material must be removed from
the contacting surfaces.
