Electrical connection
6.1 Connecting the machine
Screw the screw-type connection into the housing or fasten with a nut.
Note
The screw-type connections must have been matched to the connecting cables used (diameter
armoring, braid, shield).
For the screw-type connections, comply or exceed the requirements relating to IP degree of
protection (water and dust) - as well as the temperature range in operation stamped on the
rating plate.
6.1.2.8
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.
