Electrical Installation
Additional warnings or restrictions may apply depending on type of Hazardous approval. See
Appendix B: Product Certifications for details.
4.2 Wiring and power supply requirements
Wiring and power supply requirements can be dependent upon the approval certification. As
with all F
OUNDATION™ fieldbus requirements, a conditioned power supply and terminating
resistors are required for proper operation.
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 manual. Failure to do so may impair the
protection provided by the equipment.
 Any substitution of non-recognized spare parts may jeopardize safety. Repair, e.g.
substitution of components etc. may also jeopardize safety and is under no
circumstances allowed.
 Do not perform any service other than those contained in this manual unless you are
qualified.
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 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 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.
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 Series 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 transmitter 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.
