WARNING!
EXPLOSION HAZARD
In accordance with IEC 60079-0: 2011 Clause 30.
The purge controller bypass function shall only be enabled during setup or maintenance and
only when the area is known to be non-hazardous.
Failure to observe this warning could cause an explosion or potentially hazardous situation
which, if not avoided, may cause death or personal injury.
The customer supplied circuit breaker must be in accordance with ATEX / IECEx / North
American protection concepts. The main power isolator controls the application of
electrical power to the analyzer.
Electrical protection for the instrumentation circuitry of the analyzer is provided by fuses
F1 and F2 located inside the analyzer.

Instruments providing screw terminals for electrical connections may require working
near live parts.
Rosemount CT5800 gas analyzers do not have power switches and are operable when
connected to power.
A customer-supplied power switch or circuit breaker (complying with IEC 60947-1/ -3)
must be in the building installation. The switch has to be installed near the analyzer,
must be easily accessible, and has to be assigned as a disconnector for the analyzer.
Disconnect instruments with screw terminals from power when working at power
terminals (pull power plug or operate power switch / circuit breaker in building
installation).
The analyzer provides a protective earth terminal. To prevent electrical shock hazards,
connect the instruments to a protective earth. The instruments must be connected to
power with a three wire power cable with earth conductor. Any interruption of the
earth connector inside or outside the instrument or disconnecting the earth terminal
may cause potential electrical shock hazard.
