WARNING
Explosion hazard
If you commission a gas chromatograph in an environment with an explosive
atmosphere, you must observe the directives for explosion protection.
Switch off the gas chromatograph when carrying out repairs or maintenance as soon
as atmospheric air penetrates into it, in other words:
– When the device is opened.
– When work is carried out on carrier gas lines and sample gas lines.
Also disconnect other energy sources, e.g. Ethernet and Modbus, if these do not
have an appropriate explosion-proof design.
You require a fire permission certificate if you transport a PC or laptop through a
hazardous zone and/or if you wish to open a chromatograph in zone 1.
It is essential to observe the information in Section General regulations (Page 12).
