WARNING: Toxic and corrosive substances in parts with sample gas contact
Depending on the sample gas composition, toxic or caustic substances could be
contained in the parts of the MCS200HW and the upstream gas path which come into
contact with the sample gas.
▸
Before working on the gas path, ask the operator which gases have been applied to
the MCS200HW.
▸
Ask the operator whether, and how, the MCS200HW gas path has been cleaned.
▸
If necessary, clean the gas path with a suitable method.
▸
In case of doubt, take suitable safety precautions before working on the gas path:
Provide adequate ventilation at the workplace or work under a vent. Wear protective
goggles or a safety mask, protective gloves and acid-proof protective clothes.
WARNING: Explosion hazard through explosive sample gas
!
▸
Do not apply explosive gases to the MCS200HW.
DANGER: Risk of burns due to hot surface.
Allow the MCS200HW to cool down before carrying out any work.
The five safety rules for working on electrical systems must be observed at all times.
1
Switch off and disconnect from the power supply
2
Secure against switching on
3
Determine no voltage is applied
4
Ground and short-circuit
5
Cover or barrier off adjacent live parts
Risk of destruction of electronic components by electrostatic discharge (ESD)
When touching electronic subassemblies, there is a hazard of severe damage to the
subassembly by electric potential equalization.
▸
Make sure you have the same electric potential as the subassembly (e.g. by grounding) before touching the
subassembly
