Installation of Units with Optional EMI Filter Module
If an optional EMI filter module is supplied, it is normally
mounted below the drive with its own mounting plate.
When mounting the drive and EMI filter, it is important to
ground the filter mounting plate through its mounting
bolts. Because the aluminium enclosure of the drive and
EMI filter module is anodized and electrically insulating,
serrated washers must be used to penetrate the
anodization, or the anodized surface must be removed.
The wiring must be done as shown in the figure below.
Also refer to EMI filter manual for further information.
Shielded Wiring
Serial Communication
The wires for serial communication must be shielded.
The shield must be mounted by means of a bracket as
shown in the figure below.
Control Wiring
The control wiring must be shielded. The shield must be
mounted to the clamp supplied on the drive. See the
figure below.
Motor Wiring
Either shielded or unshielded cables can be used for the
motor. If unshielded motor cables are used, RFI
emissions will be greater. If shielded motor cables are
used, the shield must be connected both to the enclosure
of the drive and to the motor enclosure. It is important to
connect the shield by means of a clamp, so as to avoid
inter-twisted cable ends.
