Make sure you use the specific cable gland.
On devices supplied with a certificate, the explosion protection
is designed as follows:
Housing F12/F23 - EEx ia:
Power supply must be intrinsically safe.

Connect up the Micropilot M as follows:
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.
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.
Make connection (see pin assignment).
Re-insert terminal module.
Tighten cable gland (6).
Tighten screws on cover plate (4).
Insert display if fitted.
