CAUTION
If process temperatures will exceed 392 °F (200 °C), use anti-seize
compound on stud threads to ease future removal of the transmitter.
6. Insert sample and exhaust tubes through the opening in the mounting
flange and bolt the unit to the flange.
CAUTION
Uninsulated stacks or ducts may cause ambient temperatures in the
electronics housing to exceed 185 °F (85 °C) and damage the electronics.
If insulation is removed to access the duct for mounting the transmitter,
make sure to replace insulation afterward.
2.2.3 Enclosures
The Rosemount OCX8800 enclosures are designed to meet ingress conditions of
IP66. Each enclosure cover is threaded to its base and sealed with an O-ring that
isolates the threads from external contaminants.
Each cover is secured by a clip attached to the base that engages the cover
between the ribs of the cover sidewall. The clip is held in place by an Allen head
cap screw and lockwasher mounted in a recess. To remove or install the cover,
you will need an Allen wrench to loosen and tighten the screw.
2.3 Electrical installation
All wiring must conform to local and national codes. Figure 2-10 shows factory
wired solenoid power connections.
WARNING
Failure to lock out power could result in serious injury or death.
Disconnect and lock out power before connecting the transmitter to the power
supply.
WARNING
Failure to install covers and ground leads could result in serious injury or death.
