inside a standard control cabinet.
4.4.3 Measures required
Control cabinet assembly board
( For HF grounding, only use mounting plates with an excellent conductive
surface (e.g. zinc-coated surface).
( If you use mounting plates with badly conductive surfaces (e.g. painted,
anodized, yellow passivated):
- Remove the paint or coating from the contact surface of the mains filters,
controllers, and screen connections, to provide a large and conductive
connection.
( When using several mounting plates, connect them with a surface as large
as possible (e.g. using copper bands).
( Connect the controller, RFI filter and mains choke to the grounded
mounting plate with a surface as large as possible.
Power connection
( Avoid unnecessarily long cables
( Ensure the separation of motor cable and signal or mains cable.
( Ensure separation of unscreened and screened cables (distance > filter
length)
( Ensureadistanceasshortaspossiblebetweentheconductors
(single- c ores)
( Both ends of unused cores should be connected to ground/PE.
