10.1 safety information

Safety information, see Safety manual DG (identical 
to DG..T) – www.docuthek.com.

10.2 Ambient conditions

Maximum medium and ambient temperatures: 
DG:-40 to +140°F (-40 to +60°C). 
DG..S: 5 to +140°F (-15 to +60°C).
Long-term use in the upper ambient temperature 
range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact 
manufacturer).

The set switching point may palpably change in media 

and ambient temperatures below -22°F (-30°C).

Transport temperature = ambient temperature.

Storage temperature: -4 to +104°F (-20 to +40°C).
Enclosure: IP 65.

This unit is not suitable for cleaning with a high-pres-

sure cleaner and/or cleaning products.
