February 2020 Quick Start Guide
1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount 5408
Level Transmitter with Modbus® Protocol.
WARNING
Failure to follow safe installation and servicing guidelines could result in
death or serious injury.
• Ensure the transmitter is installed by qualified personnel and in
accordance with applicable code of practice.
• Use the equipment only as specified in this Quick Start Guide. Failure to
do so may impair the protection provided by the equipment.
• For installations in hazardous locations, the transmitter must be installed
according to the Rosemount 5408 Product Certifications document and
System Control Drawing (D7000005-811).
• Repair, e.g. substitution of components, etc. may jeopardize safety and
is under no circumstances allowed.
Explosions could result in death or serious injury.
• Verify that the operating atmosphere of the transmitter is consistent
with the appropriate hazardous locations certifications.
• Before connecting a handheld communicator in an explosive
atmosphere, ensure the instruments are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
• In Explosion-proof/Flameproof installations, do not remove the
transmitter covers when power is applied to the unit.
• Both transmitter covers must be fully engaged to meet Explosion-proof/
Flameproof requirements.
Electrical shock could cause death or serious injury.
• In Explosion-proof/Flameproof installations, avoid contact with the leads
and terminals. High voltage that may be present on leads can cause
electrical shock.
• Ensure the mains power to the transmitter is off and the lines to any
other external power source are disconnected or not powered while
wiring the transmitter.
Quick Start Guide 3
Quick Start Guide February 2020
WARNING
Process leaks could result in death or serious injury.
• Ensure that the transmitter is handled carefully. If the process seal is
damaged, gas might escape from the tank.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.
CAUTION
Hot surfaces
The flange and process seal may be hot at high process temperatures. Allow
to cool before servicing.

7 Adjust display orientation (optional)
To improve field access to wiring or to better view the optional LCD display:
Prerequisites
Note
In high vibration applications, the transmitter housing must be fully
engaged into the sensor module to meet the vibration test specifications.
This is achieved by rotating the transmitter housing clockwise to thread
limit.
Procedure
1. Loosen the set screw until the transmitter housing can rotate
smoothly.
2. First, rotate the housing clockwise to the desired location. If the
desired location cannot be achieved due to thread limit, rotate the
housing counterclockwise to the desired location (up to 360° from
thread limit).
3. Re-tighten the set screw.

8 Prepare the electrical connections
8.1 Cable selection
RS-485 bus
Power
supply
Use wire rated at least 5 °C above maximum ambient temperature.
Use shielded twisted pair wiring with a characteristic
impedance of 120 Ω (typically 24 AWG).
Use 24-14 AWG wire. Twisted pairs and shielded wiring are
recommended for environments with high EMI
(electromagnetic interference).
8.2 Cable gland/conduit
For explosion-proof/flameproof installations, only use cable glands or
conduit entry devices certified explosion-proof or flameproof.
8.3 Grounding
Make sure grounding is done according to national and local electrical
codes. Failure to do so may impair the protection provided by the
equipment.
Transmitter housing
The most effective grounding method is direct connection to earth ground
with minimal impedance. There are two grounding screw connections
provided (see Figure 8-1).
Figure 8-1: Ground Screws
A. Internal ground screw
B. External ground screw
Cable shield grounding
Make sure the instrument cable shield is:
• Trimmed close and insulated from touching the transmitter housing.
• Connected to a good earth ground at the power supply end.

A. Insulate shield and drain wire
B. Minimize distance
C. Connect drain wire to a good earth ground
Note
Do not ground the shield and its drain wire at the transmitter. If the cable
shield touches the transmitter housing, it can create ground loops and
interfere with communications.
Common signal reference ground for RS-485
Best practice is to connect a third reference wire to the "COM" terminal
(common signal reference ground).
If a common reference wire is not used, then the "COM" terminal should be
connected to the “–“ power terminal. The common mode difference
between the host RS-485 and the negative power supply must be between
-7 V and +12 V.

housing clockwise to thread limit.
10.2.2 Electromagnetic compatibility (EMC)
• EMC Directive (2014/30/EU): EN 61326-1
• EN 61326-2-3

wire interconnecting the COM terminals of the RS-485 network, termination
at each end, and good protective earth.

• Industry Canada RSS 211
(5) In challenging applications where the dynamic of the transmitter sensitivity is
utilized by multiple factors such as small aperture antenna, very low product
dielectric constant and/or turbulent surface, the margin for additional influence due
to extreme EMC may be limited.

The ambient temperature limits may be further restricted by the process
temperature as described by Figure 11-1.
Figure 11-1: Ambient Temperature vs. Process Temperature
A. Ambient temperature °F (°C)
B. Process temperature °F (°C)
Aside from ambient temperature variations, heat from the process may be
transferred to the transmitter housing. Being exposed to a high process
temperature without extra cooling for an extended period of time may
cause the electronics temperature to exceed the allowed limit and thereby
affect the transmitter's performance and reliability. The latter are potential
risks whenever a transmitter has shut down due to high electronics
temperature. The transmitter will warn about the electronics temperature
being out of limits.
