●
Unscrew housing cover (2).
●
Remove any display (3) if fitted.
●
Remove cover plate from terminal compartment (4).
●
Pull out terminal module slightly using "pulling loop" (only 2-wire).

Insert cable (5) through gland (6).
A standard installation cable is sufficient if only the analogue signal is
used. Use a screened cable when working with a superimposed
-
communications signal (HART).
Only ground screening of the line (7) on sensor side.
