Emerson 5301HxxxxxxxxxxxxxxZZ Series Reference Manual page 3

WARNING
Failure to follow safe installation and servicing guidelines could result in death or serious injury.
• Make sure the transmitter is installed by qualified personnel and in accordance with applicable code of practice.
• 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.
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.
• 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.
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 probe.
High voltage that may be present on leads could cause electrical shock.
• Avoid contact with the leads and terminals.
• Make sure 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.
• Probes covered with plastic and/or with plastic discs may generate an ignition-capable level of electrostatic charge under
certain extreme conditions. Therefore, when the probe is used in a potentially explosive atmosphere, appropriate measures
must be taken to prevent electrostatic discharge.
• Eliminate the risk of Electrostatic Discharge (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.
Electrical shock could cause death or serious injury.
• Use extreme caution when making contact with the leads and terminals.
Any substitution of non-recognized parts may jeopardize safety. Repair, e.g. substitution of components etc., may also jeopardize
safety and is under no circumstances allowed.
• Unauthorized changes to the product are strictly prohibited as they may unintentionally and unpredictably alter performance
and jeopardize safety. Unauthorized changes that interfere with the integrity of the welds or flanges, such as making
additional perforations, compromise product integrity and safety. Equipment ratings and certifications are no longer valid on
any products that have been damaged or modified without the prior written permission of Emerson. Any continued use of
product that has been damaged or modified without the written authorization is at the customer's sole risk and expense.
CAUTION
The products described in this document are NOT designed for nuclear-qualified applications. Using non-nuclear qualified
products in applications that require nuclear-qualified hardware or products may cause inaccurate readings. For information on
Rosemount nuclear-qualified products, contact your local Emerson Sales Representative.
CAUTION
This product is designed to meet FCC and R&TTE requirements for a non-intentional radiator. It does not require any licensing
whatsoever and has no tank restrictions associated with telecommunications issues.
