Establish the intended length of motor cable and refer to the
conducted emissions table for the RFI filter in Chapter 3
Data
to find
out if the RFI filter must be used in long-cable mode. Note that the
ground leakage current of the RFI filter is then increased (see Chapter 3
Data
)
Enclosure layout
3
Use one of the following enclosure layouts, depending on the
requirements of the installation:
Routine EMC precautions
Refer to Figure 4–2 which shows the
recommended layout for two Drives, and the signal and power cables.
Compliance with EMC emission standards
Refer to Figure 4–
3 which shows two Drives, two RFI filters, and the signal and power
cables.
4
Ensure the enclosure is of adequate size, and/or has adequate
forced-air cooling to ensure the maximum permissible ambient
temperature is not exceeded (from step 1).
5
For compliance with EMC emission standards, ensure the enclosure is
fitted with an unpainted metal back-plate for mounting the Drive and
RFI filter. For example, a zinc plated steel back-plate is suitable (see
Figure 4–3).
6
Ensure the Drive is installed vertically for best flow of cooling air
through the Drive and heatsink.
7
Ensure the clearance above and below the Drive will be at least 100mm
(4 in). Ensure the clearance each side of the Drive will be at least 5mm
(
1
/
4
in).
8
Mount the RFI filter at the left side of the Drive in order to minimize
the cable length between the Drive and filter.
9
Decide whether the Drive and RFI filter are to be mounted on a DIN-rail.
