9.3.5 Design and Installation in Area B – Interference-susceptible Area
of Control Cabinet
Arranging Components and Lines
Modules, components and lines in area B should be placed at a distance of at
least d1 = 200 mm from modules and lines in area A.
Alternative: Shield modules, components and lines in area B by distance plates
mounted vertically on the mounting plate from modules and lines in area A or
use shield lines.
Only connect control voltage connections in the frequency converter to the
mains via a mains filter. See "Division into Areas (zones)" on page 76.
Install the shortest possible lines between drive controller and filter.
Control Voltage or Auxiliary Voltage Connection
Only in exceptional cases should you connect power supply unit and fusing for
the control voltage connection to phase and neutral conductor. In this case,
mount and install these components in area A far away from area B and C of the
frequency converter.
Run the connection between control voltage connection of the frequency con-
verter and power supply unit used through area B over the shortest distance.
Line Routing
Run the lines along grounded metal surfaces, in order to minimize radiation of
interference fields to area A (transmitting antenna effect).
