Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-7
Hazardous Area Oxymitter DR
6. If the system has an abrasive shield,
check the dust seal gaskets. The joints
in the two gaskets must be staggered
180°. Also, make sure the gaskets are
in the hub grooves as the Hazardous
Area Oxymitter DR slides into the 15°
chamfer in the abrasive shield.
NOTE
If process temperatures will exceed
200°C (392°F), use anti-seize com-
pound on stud threads to ease future
removal of Oxymitter DR.
7. Insert probe through the opening in the
mounting flange and bolt the unit to the
flange.
NOTE
To maintain CE compliance, ensure a
good connection exists between the
mounting plate studs or earthing
screws on termination housing and
earth.
8. Ensure the Hazardous Area Oxymitter
DR is properly earthed by way of both
internal and external points.
9. If insulation is being removed to access
the duct work for Hazardous Area
Oxymitter DR mounting, make sure the
insulation is replaced afterward (Figure
2-6).
10. Ensure the installation does not obscure
the messages on either housing cover.
2-2 ELECTRICAL INSTALLATION
All wiring must conform to local and national
codes.
Disconnect and lock out power before
connecting the unit to the power
supply.
Install all protective equipment covers
and safety ground leads after installa-
tion. Failure to install covers and
ground leads could result in serious
injury or death.
To meet the Safety Requirements of
IEC 1010 (EC requirement), and ensure
safe operation of this equipment, con-
nection to the main electrical power
supply must be made through a circuit
breaker (min 10 A) which will discon-
nect all current-carrying conductors
during a fault situation. This circuit
breaker should also include a me-
chanically operated isolating switch. If
not, then another external means of
disconnecting the supply from the
equipment should be located close by.
Circuit breakers or switches must
comply with a recognized standard
such as IEC 947.
The Hazardous Area Oxymitter DR and
probe abrasive shield are heavy. Use
proper lifting and carrying procedures
to avoid personal injury.
a. Remove screw (11, Figure 4-1), captive
washer (13), and cover lock (12). Remove
left housing cover (10).
