Failure to follow safe installation and service guidelines could result in death or serious injury.
 Make sure only qualified personnel perform the installation.
 Use the equipment only as specified in this 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.
Process leaks could result in death or serious injury.
 Make sure the transmitter is handled carefully. If the process seal is damaged, gas might escape from
the tank if the transmitter head is removed from the antenna.
Explosions could result in death or serious injury.
 Verify that the operating environment of the transmitter is consistent with the appropriate
hazardous locations specifications.
 In an Explosion-proof/Flameproof installation, do not remove the transmitter cover when power is
applied to the unit.
 Before connecting a Field 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.
 Do not remove the gauge cover in explosive atmospheres when the circuit is alive.
 To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.
 To avoid process leaks, only use O-rings designed to seal with the corresponding flange adapter.
 All connection head covers must be fully engaged to meet explosion-proof requirements.
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
™
5400 Level Transmitter is off and the lines to any other
external power source are disconnected or not powered while wiring the transmitter.
High voltage that may be present on leads could cause electrical shock.
 Avoid contact with leads and terminals.
 Make sure the main power to the Rosemount 5400 is off and the lines to any other external power
source are disconnected or not powered while wiring the gauge.
Antennas with non-conducting surfaces.
 Antennas with non-conducting surfaces (e.g. rod antenna and process seal antenna) may generate
an ignition-capable level of electrostatic charge under extreme conditions. Therefore, when the
antenna is used in a potentially explosive atmosphere, appropriate measures must be taken to
prevent electrostatic discharge.
