Emc-Compliant Installation - Lenze i550 Series Project Planning Manual

EMC-compliant installation

Structure of a CE-typical drive system
The drive system (frequency inverter and drive) corresponds to 2014/30/EU: EMC Directive if
it is installed according to the specifications of the CE-typical drive system.
The structure in the control cabinet must support the EMC-compliant installation with shiel-
ded cables.
Please use highly conductive shield connections.
•
Connect the housing with shielding effect to the grounded mounting plate with a surface
•
as large as possible, e. g. of inverters and RFI filters.
Use central earthing points.
•
Matching accessories makes effective shielding easier.
Shield sheets
•
Shield clips/shield clamps
•
Metallic cable ties
•
Mains connection, DC supply
Inverters, mains chokes, or mains filters may only be connected to the mains via unshiel-
•
ded single cores or unshielded cables.
When a line filter is used, shield the cable between mains filter or RFI filter and inverter if
•
its length exceeds 300 mm. Unshielded cores must be twisted.
In DC-bus operation or DC supply, use shielded cables.
•
Only certain inverters are provided with this connection facility.
