DANGER
Explosive atmospheres
Explosion due to ignitable sparks
Use of devices in Zone 2 and Zone 22
➤
➤
Only mount the device if there is no potentially explosive atmosphere present.
➤
➤
Protect the device’s connector against accidental removal during operation using
safety clip M12/3GD (included in the scope of delivery).
The sensors may be mounted in any orientation. The maximum torque when mounting the sen-
sors is 20 Nm.
➤
➤
Clean the assembly area and the surroundings.
➤
➤
If using an assembly aid: Secure the sensor in the assembly aid.
➤
➤
Assemble the sensor or assembly aid at the intended operation site.
➤
➤
Ensure that the rear connector can still be reached.
➤
➤
Mount the sensor so that the blind zone is clear of any relevant objects (see wave patterns or
technical data).

If using more than one ultrasonic sensor in an application: Avoid overlapping of sonic cones.
An overlap may occur if two sensors are assembled closer than 200 mm (RU40…), 450 mm
(RU130…), 1000 mm (RU300…) or 2000 mm (RU600…) to one another. If this distance is
undershot, synchronize the sensors using IO-Link.
