Electrical connection
6.1 Connecting the machine
Remove insulation from the ends of the conductors so that the remaining insulation almost
reaches the cable lug.
Note
The direct contact between the cable lug surfaces and the contact nuts or contact screws ensure
that the connection can conduct current.
6.1.3.9
Minimum air clearances
After proper installation, verify that the minimum air clearances between non-insulated parts
are maintained. Be aware of any protruding wire ends.
Table 6-2
Values apply at an installation altitude of up to 2000 m.
When determining the required minimum air clearance, the voltage value in the table may be increased by
a factor of 1.1, so that the rated input voltage range is taken into account during general use.
