February 2020 Quick Start Guide

1 About this guide

This Quick Start Guide provides basic guidelines for the Rosemount 5408
and 5408:SIS Level Transmitters. Refer to the Rosemount 5408 and 5408:SIS
with HART® Reference Manual and Rosemount 5408 with FOUNDATION
Fieldbus Reference Manual for more instructions. The manuals and this
guide are also available electronically on Emerson.com/Rosemount.

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 manual. 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 and 5408:SIS Product Certifications
document and System Control Drawing (D7000002-885).

• 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 and Non-Incendive/Type n 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 and Non-Incendive/Type n 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.
