5.2 Installation according to EMC (installation of a CE−typical drive system)
The measures described must be carried out to comply with the EMC standards specified.
Control cabinet mounting plate
For HF earthing, only use mounting plates with an electrically conductive surface
ƒ
(e.g. zinc−coated surface).
If you use mounting plates with poor conducting surfaces (e.g. painted, anodised,
ƒ
yellow chromated):
– Remove the paint or coating from the contact surfaces of the mains filter,
regenerative power supply module and shield connections to provide a
large−surface, electrically conductive connection.
If you use several mounting plates, connect them with a surface as large as possible
ƒ
(e.g. by copper bands).
Provide a surface contact as large as possible between the regenerative power
ƒ
supply module, mains filter and the earthed mounting plate.
Control cables
The control cables must always be shielded.
ƒ
Connect the shields of the control cables on both sides.
ƒ
If you expect potential differences, install an additional equalising cable.
