5.3 Requirements for commissioning
The following requirements must be met before you commission the device:
• The device has at least one analyzer module.
• All required gas lines and equipment are connected to the device.
• No gas has been introduced into the device.
Information on how to connect the gas lines correctly is available:
• in the section "Gas connections (Page41)" and
• in the device-specic operating instructions.
If you are using an Ex p safety device for the pressurized enclosure system, you will nd
the required information in the corresponding documentation. Additional information is
available in the section "Ex px safety equipment (Page107)".
5.4 Checking gas paths for leaks
The analyzers may only be used if all required gas inlet and outlet lines have been connected
prior to commissioning. Hazardous and/or ammable gases may only be introduced after all gas
paths were tested for leaks and tightness with 1.5 times the respective maximum permissible
operating pressure.
The device operator is responsible for the required gas inlet and outlet lines. In case of a
device used with pressurized enclosure Ex p, these must also correspond to "Pressurized
enclosure" protection requirements and must be tested separately in accordance with the
ENIEC60079-2 standard.
