Assembly
ƒ Connect the ECS modules, RFI filters, and mains choke to the earthed 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.
ƒ If you use the ECSxK... capacitor module:
– 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.
ƒ If you use several mounting plates:
– Connect as much surface of the mounting plates as possible (e.g. with copper
bands).
ƒ 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 output.
ƒ Lay the cables as close as possible to the reference potential. Freely suspended
cables act like aerials.
Filters
Only use RFI filters and mains chokes which are assigned to the power supply modules:
ƒ RFI filters reduce impermissible high−frequency interferences to a permissible value.
ƒ Mains chokes reduce low−frequency interferences which in particular depend on the
motor cables and their lengths.
