Alternatively, in addition to the broad area gland plate, you can twist the
screen braid at the end and connect to the protective earth with a cable lug.
To prevent EMC disturbance, this twisted shielding connection should be
made as short as possible.
Prevent the screen from becoming unbraided at the other end of the control
cable, e.g. by using a rubber grommet. The screen braid must not make any
connection with the protective ground here because this would cause prob-
lems with an interference loop.
We recommend connecting the loads connected to the relay contact as
follows:

250 V ∼: ≦ 6 A
