Using reduction collars

Overview
Reduction collars ensure touch protection according to IEC 60529. They are included in the
Terminal Kit of the Motor Module.
To ensure touch protection IPxxB, you must use reduction collars for cable cross-sections of
16 mm² - 95 mm² (AWG 6 - AWG 3/0). For larger cable cross-sections, touching the threaded
studs and cable ends can be ruled out when the cover is closed.
Procedure
Figure 8-84
The maximum diameter of the cable with a reduction collar is 11 mm and after cutting out
the tabs, 15 mm.
