Failure to follow these installation guidelines could result in death or serious injury:
Ensure that only qualified personnel perform the installation.

Installation of this transmitter in an explosive environment must be in accordance with the appropriate

local, national, and international standards, codes, and practices.
Explosions could result in death or serious injury.
Before connecting a handheld communication device in an explosive atmosphere, make sure that the

instruments are installed in accordance with Intrinsically Safe or non-incendive field wiring practices.
Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous

locations certifications.
When connecting an external device to the Rosemount 928 Wireless Gas Monitor's discrete output in a

hazardous area, ensure that the external device is installed in accordance with Intrinsically Safe or
non-incendive field wiring practices.
Electrical shock could cause death or serious injury.
Use extreme caution when making contact with the leads and terminals.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: This

device may not cause harmful interference. This device must accept any interference received, including
interference that may cause undesired operation.
This device must be installed to ensure a minimum antenna separation distance of 7.9 in. (20 cm) from all

persons.
Replace the power module as soon as possible after receiving a low battery warning. If this is not done

promptly, the device will cease to function.
The power module may be replaced in a hazardous area. The power module has a surface resistivity greater

than 1 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 buildup.
The surface resistivity of the antenna is greater than 1 Gigaohm. To avoid electrostatic charge buildup, do

not rub or clean the antenna with solvents or a dry cloth.
 Substitution of components may impair intrinsic safety.
