5.1 Safety instructions
WARNING
Hazardous contact voltage
Risk of injury through hazardous contact voltage when the device is open or not completely
closed.
The degree of protection speci󹪝ed on the nameplate or in Technical speci󹪝cations (Page51)
is no longer guaranteed if the device is open or not properly closed.
• Make sure that the device is securely closed.
WARNING
Use of 󹪞ammable and toxic gases
If 󹪞ammable gases including occasionally explosive gases (Ex Zone 1) are discharged from
ULTRAMAT 23 equipment, a solenoid valve is part of the containment system and the zero-
point calibration (AUTOCAL) is not performed with air instead of inert gas, a daily AUTOCAL has
to be performed. In this way, a possible leakage at the solenoid valve gasket can be detected
through zero point deviation during calibration.
If a zero point deviation occurs for this con󹪝guration, the device must be taken out of operation
immediately and a leak test must be performed, in particular of the solenoid valve.
In hazardous areas (Zone 2), measuring of 󹪞ammable gases is only permissible with the option
-E21.
CAUTION
Loss of degree of protection
Damage to device if the enclosure is open or not properly closed. The degree of protection
speci󹪝ed on the nameplate or in Chapter "Technical speci󹪝cations (Page51)" is no longer
guaranteed.
• Make sure that the device is securely closed.
