Other ways of doing the installation may have just
as good an EMC performance, provided the above
guide lines to engineering practice are followed.
If the installation is not carried out according
to the guideline and if unscreened cables and
control wires are used, some emission require-
ments are not complied with, although the im-
munity requirements are fulfilled. See the para-
graph EMC test results.
• Safety earth connection
The frequency converter has a high leakage cur-
rent and must be earthed appropriately for safety
reasons acording to EN 50178.
The earth leakage current from the frequency
converter exceeds 3.5 mA. To ensure a good me-
chanical connection from the earth cable to the
earth connection (terminal 95), the cable cross-
section must be at least 10 mm2 or 2 rated earth
wires terminated separately.
