4. Unscrew the screw (1) and
remove upper part of the cover (2).
5. Unscrew the threaded cable connection (3),
remove the plug (if there is one) and lead
the cable (4) for the supply voltage through.

10. Between the Gnd connection and the piping,
X1.2 X1.1
a potential difference is not admissible.
If required, potential equalisation in accordance
with VDE 0100 / IEC 60364 must be provided for.
