to the mounting plate below the axis module with a large surface.
Recommendation: For the shield connection, use ground clamps on
bare metal mounting surfaces.
If contactors, motor−protecting switches or terminals are located in the

motor cable:
Connect the shields of the connected cables and connect the shields to
the mounting plate, too, with a surface as large as possible.
Connect the shield in the motor terminal box or on the motor housing to
ƒ
PE:
Metal glands at the motor terminal box ensure a large−surface
connection of the shield and the motor housing.
Shield the control cables:
ƒ
Connect both shield ends of the digital control cables.
Connect one shield end of the analog control cables.
Always connect the shields to the shield connection at the axis module
over the shortest possible distance.
Using the axis modules in residential areas:
ƒ
Additionally dampen the shield in order to limit the interfering
radiation: ³10 dB . This can be implemented by using standard, closed,
metallic, and earthed control cabinets or boxes.
Earthing
Earth all metallically conductive components (e. g. power supply module,
ƒ
capacitor module, axis module, RFI filter, motor filter, mains choke) using
suitable cables connected to a central point (PE bar).
Maintain the minimum cross−sections prescribed in the safety
ƒ
regulations:
For the EMC, not the cable cross−section is important, but the cable
surface and the contact surface which should be as large as possible.
