3.4 Connection and Wiring System
The wiring technique is important for gaining excellent results without disturbances. Shown below are
connection schemes.
As shown, the filter must be placed before the transformer (where required).
--All connections of the Net filters must be shielded and shouldn't be longer than the length shown in the
scheme.
--the cable shield must cover the entire length of the wire and be as close as possible to the connection
terminals.
--the shielded earth connection cable should be accomplished.
--Always use shielded cable (twisted) to connect the motor and drive.
--Avoid passing signal and power cables through the same channels.
It is very important that the panel where the filter is mounted is connected to earth.
Power and Command/Signal conductors should not be placed in the same channels (keep separate). Avoid
twisting, crossing, and etc.. It crossing is inevitable, try to cross at a 90 degree angle. Where possible use
metallic channels connected to earth.
This type of shielding (pressed cable) is better when used on conductors close to the filters and drives.
Ground and Screen Connections
It is important that the drive's ground connections are done using the shortest possible method.
These connections shouldn't be longer than 15cm. the next page shows the connection using terminals
fixed to the drive's base (bottom). this connection also reduces disturbances in the net.
