WIKA IPT-11 - Manual (Page 15)

Take note of the corresponding installation regulations for Ex
applications. In particular, make sure that no potential equalisation
currents flow over the cable screen. In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.

1 Unscrew the housing cover
2 If an indicating and adjustment module is installed, remove it by
turning it slightly to the left.
3 Loosen compression nut of the cable entry
