Installation
l Connect the Controller, mains fitter, and mains
Choke
to the
grounded mounting plate. Zinc-coated mounting plates
allow
a
permanent contact.
If
the mounting plates are painted, the paint
must be removed in
every
case.

When using several mounting plates they
must
be connected
with as large surface as possible
(e-g.
using
topper
bands).
l Connect the
Screen
of the motor cable to the
Screen
connection
of the Controller and to the mounting plate of a surface as large
as possible. We recommend to use ground
clamps
on bare
metal mounting
surfaces
to connect the
Screen
to the mounting
plate with as large surface as possible,
-
screened cable
urface
If contactors, motor
protection
switches or terminals are located
in the motor cable, the screens of the connected cables must
also be connected to the mounting plate with as
[arge
surface
as possible.
PE and the
Screen
should be connected in the motorterminal
box.
Metal
cable glands at the motor
terminaJ
box ensure a
connection of the
Screen
and the motor housing with as large a
surface as possible.
If
the mains cable between mains filter and Controller is longer
than 0.3 m, the cable must be screened. Connect the
Screen
of
the mains cable directly
to
the Controller
moduie
and to the
mains filter and connect it to the mounting plate with as large as
possible surface.
When using a brake resistor, the
Screen
of the brake resistor
cable
must
be directly connected to the
controller
and the brake
resistor and it must be connected to the mounting platte with a
surface
as large as possible.
The control cables must be screened. Digital
contra1
cables
must be screened at both ends. Connect the screens of the
contra! cables to the
Screen
connections of the Controllers
leaving as
little
unscreened cable as possible.
When using the Controllers in residential areas an additional
screening with a damping of
Z
10
dß
is required to
limit
the
noise emission. This is usually achieved by installation into
enclosed, grounded conrol cabinets or boxes made of metal.
Please note:
l If units,
which
do not comply with the noise immunity EN
50082.
2 required by the CE, are operated next to the Controllers, an
electromagnetic
interference of these units is possible.
