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.
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 5400 Series transmitter is off and the lines to
any other external power source are disconnected or not powered while wiring
the transmitter.
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.
