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.

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.
