CABINET
The drawing shows a cabinet with an electroplated zinc coated back plane, which is arealy
conducted to earth. This design will bring the following advantages:
- All parts mounted on the back plane are arealy conducted to earth.
- All screen connections will have a very low impedance to the earth.
General component placement within the cabinet:
There should be a spatial separation between power wiring (motor and power cable)
and control wiring.
o
SCREEN CONNECTIONS
All connections between the components should be wired with screened cables.
The cable screens should be connected to screen clamps on both sides.
With this wiring a very good screening effect can be achieved, because the clamps are arealy
conducted to the cabinet back plane.
p
EMC - FILTER
The EMI or main filter should be mounted next to the power supply.
For the connection to and from the main filter screened cables should be used. The cable
screens should be connected to screen clamps on both sides.

WIRING OF SCREENED CABLES
r
EARTHING
For safety reasons (VDE0160), all components must be connected to earth with a separate
cablelead.
The diameter of the cablelead must be at minimum 10mm².
An earth connetion from the power side must be linked to the housing of the main filter.
Between the main filter and the power supply, no earth connection has to be wired.
s
Y-CAPACITOR
The connection of the regeneration resistor can cause radio emission to be very high. For
minimisation of these emissions it is recommended that a Y-capacitor is connected as shown.
The capacitor should only be connected between the resistor housing and terminal pin R1.
Recommendation: 0,1µF / 250VAC Type: PME265 Supplier: RIFA
