Guidelines
Warning: Do not install the system in any hazardous area other than those
approved. Refer to the equipment tag for the specific approvals applicable to
the configuration of your instrument.
Warning: Do not apply power to the instrument in any hazardous area unless
the safety ground is properly wired inside the instrument and the cover is
properly installed.
General
Review the following guidelines when planning gauge installation.
1. Correct power source for the detector:
a. 11 – 32 VDC, 770 mA max, at detector input
b. 100 to 240 VAC, 50/60 Hz, 300 mA max (with AC power option)
2. Operating temperature range: -40°C to 75°C (-40°F to 167°F)
3. Ensure enough clearance exists to install and service the detector. Refer to the
appropriate drawings for your type of gauge and mount (Appendix C).
4. Position the source so that the radioactive source identification tag is visible and
upright, if possible.
Note: Do not paint or overcoat the source housing without first masking its
identification tag and other labeling. All labels on the source housing must
remain visible.
5. Do not mount the gauge where process overflow or other material can collect in
the beam path. The source shutter mechanism must be kept free of debris.
Caution: Do not place your hand between the source and the vessel wall. Use a
brush or other tool to remove accumulated debris.
Mounting
Warning: Installation must be in accordance with local and national electric
codes for the area classifications.
Warning: The handle of the source housing must be in the OFF position
during installation.
Warning: Do not reach inside the source housing at any time during
installation.
Warning: Use proper lifting procedures during installation to avoid injury.
