For use with Rosemount power module P/N 753-9220-XXXX only
Special Conditions for Safe Use (X)
The surface resistivity of the antenna is greater than one gigaohm. To
avoid electrostatic charge build-up, it must not be rubbed or cleaned with
solvents or a dry cloth.
The power module may be replaced in a hazardous area. The power
module has surface resistivity greater than one gigaohm and must be
properly installed in the wireless device enclosure. Care must be taken
during transportation to and from the point of installation to prevent
electrostatic charge build-up,
