Point of Connection for Environment Grounding Conductor at Machine, Installa-
tion, Control Cabinet
The equipment grounding conductor of the power cable of the machine, installa-
tion or control cabinet has to be permanently connected at point PE and have a
2
cross section of at least 10 mm
or to be complemented by a second equipment
grounding
conductor
via
separate
terminal
connectors
(according
to
EN 61800-5-1: 2007, section 4.3.5.4). If the cross section of the outer conductor
is bigger, the cross section of the equipment grounding conductor must be ac-
cordingly bigger.
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
54.
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).
