Section 1 Introduction

1.1 Safety messages

Procedures and instructions in this manual may require special precautions to ensure the safety

of the personnel performing the operations. Information that raises potential safety issues is

indicated by a warning symbol ( ). Refer to the safety messages listed at the beginning of each

section before performing an operation preceded by this symbol.

Failure to follow safe installation and service guidelines could result in death or

serious injury.

 Make sure only qualified personnel perform installation or service.

 Use the equipment only as specified in this Reference Manual. Failure to do so may

impair the protection provided by the equipment.

 Do not perform any services other than those contained in this manual unless you are

qualified.

Explosions could result in death or serious injury.

 Verify that the operating environment of the transmitter is consistent with the

appropriate hazardous locations specifications. See Product Certifications on

page 159 in this Reference Manual.

 In an Explosion-proof/Flameproof installation, do not remove the transmitter covers

when power is applied to the unit.

 Eliminate the risk of ESD discharge prior to dismounting the transmitter head.

Probes may generate an ignition-capable level of electrostatic charge under extreme

conditions. During any type of installation or maintenance in a potentially explosive

atmosphere, the responsible person should make sure that any ESD risks are

eliminated before attempting to separate the probe from the transmitter head.

 Before connecting a HART

-based Communicator in an explosive atmosphere, make

sure the instruments in the loop are installed in accordance with intrinsically safe or

non-incendive field wiring practices.

 To avoid process leaks, only use O-rings designed to seal with the corresponding

flange adapter.

Electrical shock can result in 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 main power to the Rosemount 3300 Series Transmitter is off and the

lines to any other external power source are disconnected or not powered while wiring

the transmitter.

Temperature restrictions apply for Explosion-proof versions. For limits, see

certificate-specific information in the Product Certifications chapter in this

document.
