Operating Instructions - VEGAPULS 54K enamel

3.2 Connecting the sensor
After mounting the sensor at the measurement
location according to the instructions in
chapter "4 Mounting and installation“, loosen
the closing screw on top of the sensor. The
sensor lid with the optional indication display
can then be opened. Unscrew the sleeve nut
and slip it over the connection cable (after
removing about 10 cm of cable mantle). The
sleeve nut of the cable entry has a self-locking
ratchet that prevents it from opening on
its own.

The terminals hold the wire without a screw.
Press the white opening levers with a small
screwdriver and insert the copper core of the
