Electrical installation
Installation according to EMC (installation of a CE−typical drive system)
Shielding
Connect the motor cable shield to the axis module
ƒ
–
with the ECSZS000X0B shield mounting kit.
–
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
ƒ
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.
