Further EMC precautions
Further EMC precautions are required if more stringent EMC emission requirements apply:
•
Operation in the first environment of EN 61800-3
•
Conformity to the generic emission standards
•
Equipment which is sensitive to electrical interference operating nearby
In this case it is necessary to use:
•
The optional external EMC filter
•
A shielded motor cable, with shield clamped to the grounded metal panel
•
A shielded control cable, with shield clamped to the grounded metal panel via the
grounding bracket

Recommended cable management
Figure 4-3 Drive cable clearances
It is not necessary to remove the external EMC filter when using an IT supply.
NOTE

Signal cables
Plan for all signal cables
to be routed at least
300mm (12in) from the
drive and any power cable
Optional
braking resistor
Locate optional braking
resistor and overload
external to cubicle
(preferably near to or
on top of the cubicle).
Note
For EMC compliance:
1) When using an external EMC
filter, one filter is required for
each drive
2) Ensure direct metal contact
at drive and filter mounting
points (any paint must be
removed)
The external EMC filter can be
bookcase mounted (next to the
drive) or footprint mounted (with
the drive mounted onto the filter).
