Personnel and Equipment Safety Information

This section describes important safety information to avoid personal injury and damage to the

equipment while installing, operating, maintaining, or servicing the equipment. All safety regu-

lations, standards, and procedures at the analyzer location must be followed.

All personnel involved with the installation, start-up, operation, maintenance, service, or trou-

bleshooting of the analyzer must review and follow these Warnings and Cautions.

Warnings

Review and follow these Warnings to avoid personal injury or environmental contamination.

Always disconnect main AC power and/or external power sources (example, for relay contacts)

to the analyzer before removing any sample system assemblies and components from the ana-

lyzer, or before opening any covers on the analyzer.

If it is necessary to open the Upper/Lower Ex d Electronics Enclosures while the circuits are

live, test the area for explosive gases and proceed only when the area is safe. When the Enclo-

sures are open, take appropriate precautions to avoid electrical shock. Hazardous voltages are

present inside.

All electrical connections, adjustments, or servicing of the analyzer should be performed only

by properly trained and qualified personnel.

All electrical connections, materials, and methods (plus all safety policies and procedures) must

be made in compliance with local wiring regulations and electrical code for the hazardous area,

and be approved by the Owner Company.

Before working on the sample system, confirm that the system is purged with Zero gas and is

isolated (blocked in) from the process.

Because ultraviolet radiation can harm your eyes, avoid direct viewing of the light emanating

through the end window of the source lamp. If the source lamp must be viewed while ener-

gized, wear safety glasses that block ultraviolet radiation.

For Division 1/Zone 1 Installations, all cable entry glands (one power cable entry and two

signal cable entries) into the flameproof Disconnect Enclosure must be Ex d certified. Conduit

or cable seals that comply with the flameproof enclosure cable entry sealing requirements of the

local authority must be installed at the entries to the enclosure. In all cases, each unused cable

entry port must be plugged with a certified Ex d plug.
