Assembly
• Make the contact from controller, RFI filter, and mains chokes to
the grounded mounting plate with as large a surface as
possible. Zinc-coated mounting plates allow long-lasting
contacts. For painted plates the paint of the mounting plates
must be removed in all cases.
• If you use several mounting plates:
− Make a conductive connection of the mounting plates with as
large a surface as possible (e.g. using copper bands).
• Connect the screen of the armature and field cable to the
mounting plate with as large a surface as possible:
− Recommendation: Make the large-surface connection of the
screens to the mounting plate with earthing clamps on bare
metal mounting surfaces.
• If there are contactors, motor protection switches, or terminals
in the armature cable:
− Contact of the screens of the connected cables to each other
and to the mounting plate with as large a surface as
possible.
• In the terminal box, connect the screen of the motor to PE:
− Metal cable glands at the motor terminal box ensure a large-
surface connection of the screen to the motor housing.
• If the total length of the mains cable between RFI filter and
mains chokes and controller exceeds 200 mm:
− Screen mains cables
− Connect the screen of the mains cables to the mounting
plate with as large a surface as possible.
• Connect the screen of the control cables to the mounting plate
with as large a surface as possible.
• If you use drive systems with the types 48x in residential areas:
− Check the compliance with radio interference voltage level
(EN55022 class B) at the supply location of the operating
area.
− Check the permissible radio interference emission
(EN55022 class B) at the supply location of the operating
area.
Please note:
If devices which do not comply with the CE requirement concerning
the noise immunity EN 500882-2 are operated close to the
controllers, an electromagnetic disturbance of these devices by the
controllers is possible.
