Installation according to EMC (installation of a CE−typical drive system)
Assembly
Connect the ECS modules, RFI filters, and mains choke to the earthed
ƒ
mounting plate with a surface as large as possible:
–
Mounting plates with conductive surfaces (zinc−coated or stainless
steel) allow for permanent contact.
–
Painted plates are not suitable for an EMC−compliant installation.
If you use the ECSxK... capacitor module:
ƒ
–
Install the capacitor module between the power supply module and the
axis module(s).
–
If the total cable length in the DC−bus connection is > 5 m, install the
capacitor module as close as possible to the axis module with the
greatest power.
If you use several mounting plates:
ƒ
–
Connect as much surface of the mounting plates as possible (e.g. with
copper bands).
Ensure the separation of the motor cable and the signal or mains cables.
ƒ
Avoid a common terminal/power strip for the mains input and motor
ƒ
output.
Lay the cables as close as possible to the reference potential. Freely
ƒ
suspended cables act like aerials.
Filters
Only use RFI filters and mains chokes which are assigned to the power supply
modules:
RFI filters reduce impermissible high−frequency interferences to a
ƒ
permissible value.
Mains chokes reduce low−frequency interferences which in particular
ƒ
depend on the motor cables and their lengths.
