property damage, damage to this instrument, and warranty invalidation.
• Read all instructions prior to installing, operating, and servicing the product.
• If you do not understand any of the instructions, contact your Emerson representative for
clarification.
• Follow all warnings, cautions, and instructions marked on and supplied with the product.
• To ensure proper performance, use qualified personnel to install, operate, update, program, and
maintain the product.
• Use only factory documented components for repair. Tampering and unauthorized substitution
and parts can affect product performance and cause unsafe operation of your process.

WARNING
RISK OF ELECTRICAL SHOCK
Failure to install covers and ground leads could result in serious injury or death.
Disconnect the main power wire from the separate power source before servicing.
Do not operate or energize transmitter with case open!
Wiring connected in this box must be rated at least 240 Vac and 14 gauge.
Non-metallic cable strain reliefs do not provide grounding between conduit connections! Use
grounding type bushings and jumper wires.
Seal unused cable conduit entries securely with non-flammable enclosures to provide
transmitter's enclosure integrity in compliance with personal safety and environmental protection
requirements. Seal unused conduit openings with Type 4X or IP66 conduit plugs to maintain the
ingress protection rating (Type 4X) of transmitter's enclosure.
Operate only with front panel fastened and in place.
For safety and performance, connect and properly ground the system through a three wire power
source.
Proper use and configuration is the operator's responsibility.
Install all protective equipment covers and safety ground leads after installation.
Provide local ground connection to the transmitter in order to avoid electric shock. The ground
conductor should be equal to or greater than 16 AWG for a copper conductor in free air or 12
AWG for an enclosed copper conductor.
Disconnect and lock out power before connecting the power supply.
Disconnect and lock out power before working on any electrical components. There is voltage up
to 240 Vac. Verify the reliability and continuity of the grounding of the probe connection before
powering the equipment.
To meet the Safety Requirements of IEC 61010-1 (EC requirement) and ensure safe operation of
the equipment, make a connection to the main electrical power supply through a circuit breaker
(max 10 A) which will disconnect all current-carrying conductors during a fault situation. The
circuit breaker should also include a mechanically operated isolating switch. If it does not, then
locate another means of disconnecting the supply from the equipment close by. Circuit breakers
or switches must comply with a recognized standard, such as IEC 60947.
Ensure that all equipment doors are closed and protective covers are in place, except when
maintenance is being performed by qualified people, to prevent electrical shock and personal
injury.
WARNING
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
CAUTION
If the ducts will be washed down during outage, make sure to power down the probes and remove
them from the wash area.
When replacement parts are required, ensure that qualified people use replacement parts
specified by Emerson. Unauthorized parts and procedures can affect the product's performance,
place the safe operation of your product at risk, and void your warranty. Look-alike substitutions
may result in fire, electrical hazards, or improper operation.

WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

WARNING
ELECTRIC SHOCK
Failure to install covers and ground leads could result in serious injury or
death.
Install all protective equipment covers and safety ground leads after
installation.
CAUTION
Equipment damage
Damage to the transmitter may result.
Do not allow the temperature of the probe electronics to exceed 194 °F (90
°C)
1.1 Install probe
Emerson can supply a weld plate for welding to the flue gas duct for new
installations.
Procedure
1. If using the standard square weld plate (Figure 1-2) or an optional
flange mounting plate, weld or bolt the plate onto the duct.
The through hole diameter in the stack or duct wall and refractory
material must be at least 2.5 in. (63.5 mm).
2. Insert probe through the opening in the mounting flange and bolt
through the probe gasket and flange.
For horizontal installations, the breather port must be oriented such
that it is facing downward.
