3. The Rosemount 702 enclosure may be made of aluminum alloy and given
a protective polyurethane paint finish; however, care should be taken to
protect it from impact or abrasion if located in a Zone 0 area.

Special Conditions for Safe Use (X):
1. The surface resistivity of the antenna is greater than 1 GΩ. To avoid
electrostatic charge build-up, it must not be rubbed or cleaned with
solvents or dry cloth.
2. The Rosemount 701PBKKF Power Module may be replaced in a hazardous
area. The power modules have a surface resistivity greater than 1 GΩ and
must be properly installed I the wireless device enclosure. Care must be
taken during transportation to and from the point of installation to
prevent electrostatic charge build-up.
3. The Rosemount 702 enclosure may be made of aluminum alloy and given
a protective polyurethane paint finish; however, care should be taken to
protect it from impact or abrasion if located in a Zone 0 area.
