SECTION THREE – ELECTROMAGNETIC COMPATIBILITY (EMC)
DS2000 USER’S MANUAL (rev.C)
3.9
It is not necessary to shield the input power wires. A shielded cable should be used between
filter and drive if the separation exceeds 30 cm.
The shields of cables inside the cabinet must be 360° clamped to the cabinet wall
(see Fig. 3.6).

The power cables must be kept away from signal cables by at least 30 cm.
When the power cables cross the signal cables, this intersection must be done with angles as
near to 90° as possible.
The crossing of the cabinet should be accomplished with a low impedance (RF) connection
between cable shield and enclosure. If a connector is not involved, the shortest practical
lengths of connecting strap should be used (see Fig.3.7).
