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
Reference Manual for more instructions. The manual 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.
•Make sure 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).
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 Field Communicator in an explosive atmosphere,
ensure the instruments are installed in accordance with intrinsically safe
or non-incendive field wiring practices.
•Do not remove the transmitter cover in explosive atmospheres when the
circuit is live.
•Both transmitter covers must be fully engaged to meet explosion-proof
requirements.
Electrical shock could cause death or serious injury.
•Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
•Make sure 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.
Process leaks could result in death or serious injury.
•Make sure that the transmitter is handled carefully. If the process seal is
damaged, gas might escape from the tank.
