3.2.5

Electromagnetic compatibility

Variable speed drives are powerful electronic circuits which can cause electromagnetic interference if
not installed correctly with careful attention to the layout of the wiring.
Some simple routine precautions can prevent disturbance to typical industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that electromagnetically sensitive
equipment is located nearby, then full precautions must be observed. In-built into the drive, is an
internal EMC filter, which reduces emissions under certain conditions. If these conditions are
exceeded, then the use of an external EMC filter may be required at the drive inputs, which must be
located very close to the drives. Space must be made available for the filters and allowance made for
carefully segregated wiring. For further details relating to EMC, refer to the EMC data sheet,
CT part number 0478-0575-01.

3.2.6

Electrical safety

The installation must be safe under normal and fault conditions. Electrical installation instructions are
given in Chapter 4

Electrical installation

Hot surfaces

Care must be taken when opening the cubicle door as some components may be very hot
to touch even after the 10 minutes discharge time.

Component IP ratings

The internal cubicle components are rated to IP20. This must be taken into consideration
when the doors are opened.
