ENSOR N ET lines must always be installed separately at a
minimum distance of 20 cm from other lines that carry a voltage
greater than 60 V.
Materials required  1 x SACIQ connection cable (see chapter 12 A
CCESSORIES AND

1 Remove the protective caps from the plug connections of the
IQ sensor and SACIQ sensor connection cable and keep them
safe.
2 Plug the socket of the SACIQ sensor connection cable onto the
plug head connector of the IQ sensor. At the same time, rotate
the socket so that the pin in the plug head connector (1) clicks
into one of the two holes in the socket.
3 Then, screw the coupling ring (2) of the IQ sensor connection
cable on the IQ sensor up to the stop.
