Installation Process
Gas
The EX-Z1 and EX-Z2 systems require clean dry air or nitrogen for both
the cooler and the purge protection system. EX-IP systems may require
purge depending on the environment. See the specification tables for your
specific system for plumbing and gas supply details.
Warning
Avoid explosion hazard. Never use a flammable gas to purge the analyzer.
Purge gas must be free of contaminants.
Notice
To avoid damage to the spectrometer, do not use argon as a purge gas.
Fiber optic
Follow the manufacturer’s specifications and recommendations for fiber
optic type, material, maximum run length, minimum turn radius, and care.
For all applications, leave 1m (40”) of fiber optic in the enclosure to
connect to the spectrometer and allow serviceability. Provide SMA905
connectors to mate with the spectrometer. Label the fiber optics with their
sampling location and whether each is the “source” (from the analyzer) or
the “return” (to the analyzer) to make service and troubleshooting easier.
Use the instructions included in the spectrometer
User’s Guide
for making
internal connections to the spectrometer.
Note
On EX-Z2 systems and EX-IP systems, fiber optic cables enter the
enclosure using the same ports that are available for electrical wiring.
Hazardous installations
Fiber optic cable runs in hazardous areas where the hazardous area is non-
mining, above ground, and the hazard is caused by flammable gases or
vapors, must be connected to the enclosure through either a cable gland
with armored fiber optic cable or through a sealed conduit. This is required
because the metal shielding in fiber optic cables can be a current-carrying
conductor. See the schedule drawings that accompanied the enclosure and
the specifications for your model later in this manual for port locations and
specifications.
