Handling & Storage
This chapter addresses procedures for handling electrostatic discharge
(ESD) sensitive equipment, as well as procedures for unpacking, inspecting,
and storing of the system.
Caution This system is an ESD sensitive instrument. Use proper ESD
protective equipment and procedures. Failure to comply with ESD
procedures can result in circuit damage. 
The instrument contains electronic components that can be damaged from
discharges of static electricity: Do not touch the circuit board components.
Ordinarily, handling the circuit boards by their edges will not damage the
circuits.
Observe the following when installing, setting up, servicing,
troubleshooting, or repairing the instrument:
1. Use an antistatic bag. Most instrument subassemblies are shipped in a
special antistatic bag. When not installed, keep the assembly in the bag
as often as possible.
2. Remove ESD sensitive subassemblies only under the following
conditions:
a. When at a designated static-free workstation or when the bag is
grounded at a field site.
b. After the conductive area of the container has been neutralized.
c. After making firm contact with an antistatic mat and / or firmly
gripping a grounded individual.
3. Personnel handling ESD sensitive devices should be neutralized to a
static-free workstation by means of a grounding wrist strap that is
connected to the station or to a good grounding point at the field site.
4. Do not allow clothing to make contact with ESD sensitive devices.

Hardware Installation
Read the Gamma Radiation Safety Guide (p/n 717904) PRIOR TO
installing the equipment.
Note Copies of the drawings referenced in this manual are provided in
Appendix C. 
For detector-transmitter housing layout details, refer to drawing 868502.
For mounting dimensions, refer to drawing 868672 or 868674 for water-
cooled units.
A variety of source housings are used with the scintillation detector
depending on the requirements of the application. Refer to the appropriate
drawing for your source.
Warning The instrument is a nuclear device regulated by federal and / or
state authorities. You are responsible for knowing and following the
pertinent safety and regulatory requirements. Refer to the Gamma
Radiation Safety Guide (p/n 717904) for a summary of these
requirements. 
Warning Moving or removing an installed source housing or any assembly
that includes a source housing requires a person who is specifically licensed
to install and commission Thermo Scientific source housings. 
In the United States, your general license permits you to own and install all
of the instrument’s components, including the source housing. However,
you may not commission the instrument (remove the lock and open the
source housing shutter for the first time) without a specific license
authorizing radiation commissioning of the instrument. In Canada, you are
only allowed to remove the instrument from the shipping container if your
CNSC license has a condition authorizing mounting / dismounting of
devices. For assistance obtaining a license and / or commissioning /
decommissioning the instrument, contact Thermo Fisher Scientific.

Hardware Installation
Source-Detector Configurations
3-2 LevelPRO Installation Guide Thermo Fisher Scientific
The gauge is comprised of a source housing that contains the radioisotope
source and the detector-transmitter that contains the scintillation detector
and electronics. Sources are available in a fan beam or strip source
configuration. For most fan beams, the beam angle spreads at a 45° angle in
the vertical dimensions. A 30° beam angle spread is available with model
5210, and 60° beam angle spreads are available with models 5205B,
5206B, 5207B, and 5208B.
Strips sources emit radiation evenly along the length of the vessel from the
source and measure the radiation level reaching the detector after passing
through the vessel walls and the process material.
The scintillation detector is available in lengths ranging from 1 to 12 feet,
in 2-foot increments. For a tall or narrow tank, multiple sources and / or
detectors might be required. Contact Thermo Fisher. The specific source -
detector configuration depends on the application. Three possible
configurations are illustrated below.
Figure 3–1.
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. 
Instrument approvals are listed in Appendix B.

Thermo Fisher Scientific LevelPRO Installation Guide 3-3
Review the following guidelines when planning gauge installation:
1. Correct power source is available. See “Power Requirements” later in
this chapter.
2. You will need to supply the necessary brackets and hardware required
for mounting the gauge to the vessel.
3. Operating temperature range: -40°C to +60°C (-40°F to +140°F).
4. There should be enough clearance to install and service the source
housing and the detector. Refer to the appropriate dimensional
drawings in the drawing appendix.
5. Position the source housing so the radioactive source identification tag
is visible. Mount it so the tag is upright.
6. The gauge should not be mounted where process overflow or other
material can collect in the beam path. The source housing shutter
mechanism must be kept free of debris.
7. If the handheld terminal will be used for configuration, the connection
must be located in a safe area.
Ensure the correct power source is available. One of the following input
power sources is required: 24 Vdc ± 20% or 115/230 Vac ± 15%, 50/60
Hz (requires optional AC power board). The maximum power requirement
is 12 VA. Both DC and AC power may be supplied to the gauge at the
same time. The gauge will draw power from whichever input source
provides the higher DC source voltage.
The LevelPRO enclosure provides internal safety ground and external
safety ground lugs (reference drawing 868503) for Safety Protective Earth
Grounding. The external safety ground lug is used to connect the unit to
Earth Ground. The internal safety ground lug is used to connect the AC
power input ground line.
