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.
