4 Electrical installation
Wiring according to EMC (installation of a CE−typical drive system)
Assembly
Connect power supply modules, capacitor modules (optional), axis modules,
ƒ
RFI filters and mains choke with earthed mounting plate with a surface as
large as possible
–
Mounting plates with conductive surfaces (zinc−coated or stainless steel)
allow permanent contact.
–
Painted plates are not suitable for the installation in accordance with the
EMC.
Use of capacitor module ECSxK...:
ƒ
–
Install the capacitor module between the power supply module and the
axis module(s).
–
If the overall 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.
Use of several mounting plates:
ƒ
–
Connect as much surface as possible of the mounting plates (e.g. with
copper bands).
Ensure the separation of motor cable and signal or mains cable.
ƒ
Do not use the same terminal strip for mains input and motor output.
ƒ
Lay the cables as close as possible to the reference potential. Freely
ƒ
suspended cables act like aerials.
Filters
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 mainly depend on
ƒ
the motor cable and its length.
