information
Use a bright backing plate. Use cables and/or ground straps with
cross sections as large as possible. Route the PE-terminal
connection for the components in a star-shaped fashion and ensure
large area contact of earthing (PE) and shielding connecting on the
PE-bar of the backing plate to establish a low-resistance HFconnection.
PE-mains connection in accordance with DIN VDE 0100 part 540
Mains connection < 10 mm²
Protective conductor cross-section min. 10 mm² or use 2
conductors with a cross-section of the mains supply lines.
Mains connection > 10 mm²:
Use a protective conductor cross-section in compliance with
the cross-section of the mains supply lines.
Route the motor cable separated from signal and mains
supply lines. The minimum distance between motor cable
and signal line/mains line must be 20 cm, if necessary us
separator.
Always route the motor cable without interruptions and the
shortest way out of the control cabinet.
When using a motor contactor or a reactance control/motor
filter, this should be directly mounted to the drive controller.
Do not bare the core ends of the motor cable too soon.
Avoid unnecessary cable lengths.
The drive controllers must always be wired with screened motor
cables and signal lines. A cable type with double copper braiding
with 60 -70% coverage must be used for all screened connections.
Contactors, relays, solenoid valves (switched inductivities)
must be wired with fuses. The wiring must be directly
connected to the respective coil.
The switched inductivities should be at least 20 cm away
from the process sontrolled assemblies.
Place larger consumers near the supply.
If possible enter signal lines only from one side.
Lines of the same electric circuit must be twisted. Crosstalk
is generally reduced by routing cables in close vicinity to
earthed plates. Connect residual strands at both ends with
the control cabinet ground (earth).
