5.2.4.2 Functional earth, terminal 14

Connect the cable to an earthing point close to the softstarter. The cable should
be as short as possible. A suitable earthing point would be next to the softstarter
on the mounting plate, as shown in figures 5.8 and 5.9. The mounting plate
should also be earthed.
This is not a protective earth, it is a functional earth. The earthing cable should be
as short as possible. Maximum length 0.5 m.
