2.2.4 Pipe Connections
Refer to Appendix Piping Drawings for information about pipe connec- tions. On special systems, consult the text in the manual that describes your particular sample system in detail.
2.2.5 Sample Delivery System
The sample delivery system should be designed to operate reliably and must be of large enough capacity to avoid flow stops. A pump is required only if there is insufficient pressure to reliably supply the sample to the system equipment panel. Do not complicate the delivery system by adding a pump unless it is absolutely necessary. If a pump is required, select a type that can handle the sample (corrosion), as well as meet the area classification and Environmental conditions.
2.2.6 Venting the System
In gas analysis systems, the system vent manifold or bypass/sample vents must terminate in a safe area as the sample may be poisonous, corrosive or flammable.
2.3Electrical Connections (Rear Panel)
Figure
For safe connections, no uninsulated wiring should be able to come in contact with fingers, tools or clothing during normal operation.
CAUTION: Use Shielded Cables. Also, use plugs that provide excellent EMI/RFI protection. The plug case must be connected to the cable shield, and it must be tightly fastened to the analyzer with its fastening screws. Ultimately, it is the installer who ensures that the connections provide adequate EMI/RFI shielding.
