Electrical shock can result in death or serious injury.
Ground device on non-metallic tanks (e.g. fiberglass tanks) to prevent electrostatic charge build-up.
Single lead probes are sensitive for strong electromagnetic fields and therefore not suitable for
non-metallic tanks.
Care must be taken during transportation of power module to prevent electrostatic charge build-up.
Device must be installed to ensure a minimum antenna separation distance of 8 in. (20 cm) from all
persons.
Probes covered with plastic and/or with plastic discs may generate an ignition-capable level of
electrostatic charge under certain extreme conditions. Therefore, when the probe is used in a
potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic
discharge.
Process leaks could result in death or serious injury.
Only qualified personnel should install the equipment.
Install transmitter prior to process start-up.
Install and tighten process connectors before applying pressure.
Handle the transmitter carefully.
Do not remove the transmitter while in operation.
If the process seal is damaged, gas could escape from the tank when removing the transmitter head
from the probe.
Electronic boards are electrostatically sensitive. Failure to observe proper handling precautions for
static-sensitive components can result in damage to the electronic components. Do not remove the
electronic boards from the Rosemount
To ensure long life for your radar transmitter, and to comply with hazardous location installation
requirements, tighten covers on both sides of the electronics housing.
Any substitution of non-recognized parts may jeopardize safety. Repair, e.g. substitution of components
etc., may also jeopardize safety and is under no circumstances allowed.
Use caution when handling the Power Module. The Power Module may be damaged if dropped from
heights in excess of 20 ft. (6 m).
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 20 cm (8 in.) from all persons.
