10.3 Bonding Information
10.3 Bonding Information
General
Grounding or PE ground means the connection to protective earth. IS ground is
ground connection for the ex-systems. Bonding means additional ‘grounding’ to
protect sensitive signals from RF noise etc.
When the PE ground and IS ground connections of the robot components have been
performed in accordance with the description in this manual, the electronics
components in the shielded environment of the cabinet and manipulator are well
protected against electric noise.
To ensure proper operation of the robot system when electronic devices such as
external PLC, communication nodes, external cabinets etc. are placed outside these
protected environments, it is extremely important that proper bonding is provided
for the external units and corresponding communication cables.
In the following you will find information and hints on how proper bonding can be
obtained. For more information on protecting of signal cables etc., books describing
the subject are available on the market.
Bonding Connections
When the robot is installed in accordance with the description in this manual, all
components of the robot system; control cabinet, manipulator, purge unit and
possible external cabinets etc. will be connected by a firm bonding wire as part of
the robots design. Additional external equipment installed must be connected by a
bonding wire of minimum 16 mm
2
(AWG 4). The wire must be firmly connected to
the bare metal of the component with a solid screwed connection. A solid
connection like this will ensure that no voltage potential can be built up between the
different units.
If the robot, control cabinet, purge unit, spray booth door switch or any other device
in the robot system is mounted on a metal surface, the user must make sure that
these surfaces are properly grounded.
CAUTION!
No components in the robot system must be mounted on metal surfaces
which are not properly grounded.
