– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.

– Always use genuine spare parts.

Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.

DANGER

Electrical voltage

Electrocution hazard.

a) Disconnect the device from power supply.

b) Make sure that the equipment cannot be reconnected to mains unintentionally.

c) The device must be opened by trained staff only.

d) Regard correct mains voltage.

DANGER

Toxic, acidic gasses

Sample gas / calibrating gas can be harmful.

a) If necessary, ensure a safe gas discharge.

b) Switch off the gas supply before performing maintenance and protect from opening

inadvertently.

c) Protect yourself from toxic / corrosive gasses when performing maintenance. Wear

suitable protective equipment.

DANGER

Potentially explosive atmosphere

Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas with potentially explosive at-
mospheres.
Do not expose the device to combustible or explosive gas mixtures.
