Note special operating conditions!

• The power supply of the sensor may only be connected to the power pack PH15-2406 ( or to the power pack WAGO 787-1002 ( 9330)

• The connection cable may only be moved if the ambient temperature is above 5°C and below 70°C

• If the cable is to be connected within the hazardous area, it must have a protection class of at least IP-6x after installation or comply with another recognised type of ignition protection for this area

• The permissible ambient temperature range is -20°C to +80°C
