Make sure only qualified personnel performs the installation/maintenance/service.
Before removing the sensor, or before connecting or disconnecting the wiring, turn off the power supply. Do not
disconnect, unless the area is non-explosive.
Verify that the environmental temperature is within the temperature class required for the area.
•
Ambient temperature range is -30 °C to +50 °C.
•
Never remove the trimmer cover protector unless the area is non-explosive.
•
Adhere to the relevant national regulations and provisions.
•
The relevant installation regulations must be adhered to. In particular, take into account the requirements relating
to the temperature limitation as regards the expected dust deposits.
•
Avoid electrostatic charging on housings and cables
•
In case of cleaning the sensor, this must be done with a damp cloth, in order to prevent build-up of electrostatic
charges.
•
If fast moving particles are present a physical barrier shall protect the sensor.
•
Cable shall be protected from pulling or twisting.
•
The sensor may only be connected/supplied from a circuit having a prospective short circuit current of not
greater than 10kA.
•
The sensor must be protected against exposure to direct sunlight and other ultraviolet light sources.
