1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount 3408
Level Transmitter. Refer to the 3408 Reference Manual for more
instructions.
1.1 Safety messages
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 and the
Reference 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 3408 Product Certifications document and
System Control Drawing.
Repair, e.g. substitution of components, etc. may jeopardize safety and is
under no circumstances allowed.
WARNING
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 Ex ec installations,
do not remove the transmitter cover when power is applied to the unit.
The transmitter cover must be fully engaged to meet Explosion-proof/
Flameproof requirements.

WARNING
Electrical shock could cause death or serious injury.
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.

2. Tighten the bolts and nuts (see Table 3-1).
Note
•Re-tighten after 24 hours and again after the first temperature
cycle.
•Check at regular intervals and re-tighten if necessary.
3.2 Torque specifications
The conditions used for the calculation are:
•Standard mating metal flange
•A193 B8M Cl.2 / A4-70 bolt material
•Friction coefficient of μ=0.16
Low strength bolt and non-metallic mating flange may require lower
tightening torque.
