7�3�2 Installation
1� The protective cap is to be removed before installation. The sensor must be
handled with care to prevent damage.
2� Screw the sensor by hand into the intended installation bore and make sure
that the O-ring is not damaged during insertion.
3� Fasten the sensor with the dedicated special tool, the open-ended wrench
SW27 (R913062700). Required tightening torque M
7�3�3 Information on wiring and circuitry
• Lines from the sensor to the electronics must not be routed close to other
power-conducting lines in the machine.
• The wiring harness should be mechanically secured in the area in which
the sensor is installed (distance < 150 mm). The wiring harness should be
secured so that in-phase excitation with the sensor occurs (e.g. at the sensor
mounting point).
• If possible, lines should be routed in the machine interior. If the lines are routed
outside of the machine, their secure mounting is to be ensured.
• Lines must not be kinked or twisted, must not rub against edges and must not be
routed through sharp-edged ducts without protection.
