8 Earthing and shielding of the LMV6
4/21/2020
8.1.3 EMC-compliant wiring
Shielded cables must also be used in control panels for the bus connections
between the LMV6, SQM4, and AZL66
Each SQM4 connected to the LMV6 must be connected to the same functional
earth (FE) or earthing point via a short cable or low-resistance housing connection
as the LMV6
Ensure that the SQM4 actuator housing is in perfect electrical contact with the
functional earth (FE) (use toothed lock washers and galvanically conductive
mounting plates)
The mains cable and the bus cable must be laid separately in separate cable
channels and as far apart as possible
The cables to and from ignition equipment must be laid separately and as far as
possible from the bus cables
The high voltage cables from the ignition equipment must be short and lead directly
to the ignition electrodes
With 2-pole ignition equipment, the cables must be routed closely together in order
to keep the radiation area as small as possible
