4.1 General instructions
The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/
ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
Protect your instrument against moisture ingress through the following measures:
• Use a suitable connection cable
• Tighten the cable gland or plug connector firmly
• Face the connection cable or conduit entry downward, never upward
This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through
cleaning processes) and on cooled or heated vessels.
