SAFETY INFORMATION
▸ Therefore, in order to prevent damage, the relevant safety information and valid safety
regulations must be observed.
If the GM35 is used as a sensor in combination with a control system, the operator must
ensure that a failure or malfunction on the GM35 cannot lead to unallowed hazardous
operating states or damage.
Protection against hazards through electrical equipment
GM35 system components include electrical equipment designed for use in industrial high-
voltage plants where the relevant standards and regulations must be observed.
▸ Disconnect mains lines before working on mains connections or live parts.
Protection against hazards through gases
▸ Wear suitable protective clothing and mask when using hot and/or aggressive sample
gases resp. with high dust loads.
▸ Never open the enclosure or switch off the purge air feed without taking appropriate
protective measures when the duct is pressurized.
Troubleshooting precautions

• Maintenance personnel can be alerted immediately and at any time.
• Maintenance personnel are trained to be able to respond to malfunctions on the GM35
and correctly clear the operational malfunction involved.
• Suitable protective equipment, tools and auxiliary means are available at all times.
• Malfunctions are analyzed by qualified personnel, faults corrected, and operation
optimized to prevent similar malfunctions in the future.
