The P18(D) transducer version P18(D)-1XXX or P18(D)2XXX
has 8 connecting terminals, version P18(D)-0XXX has 4 terminals (ver-
sion without analog outputs). Access to the terminals is possible after
removing the cover of the transducer housing. You should use a multi-
conductor round wire with external diameter from 3.5 mm up to 6 mm
for electrical connections. Remove the display prior to connecting the
wires in a screw terminal of the P18D transducer. Pass supplying wi-
res through the packing and twist the packing seal in order to obtain
the leaktightness. If the packing seal is not twisted, the required IP 65
leaktightness is not ensured. The LCD display should be put back after
screwing the wires to the screw terminal of the P18D transducer.
