Only one or two shielded cables may be clamped per shielding terminal. The cable
is clamped in at the stripped cable shielding.
1. First, strip the cable shield to a length of at least 20 mm.
2. Now clamp in the stripped cable shield underneath the shielding terminal. Push
the shielding terminal towards the module and feed the cable through
underneath the clamp.
