2.3 Not intended use
Not intended use in terms of a misuse means:
• any work on the measuring equipment without observing all instructions in this operating instruction
• use of transmitter, transducer and accessory combinations not intended by FLEXIM
• installation of the transmitter, transducers and accessories in explosive atmospheres they are not approved for
• any work on the measuring equipment (e.g., installation, dismounting, connection, start-up, operation, service and main
-
tenance) carried out by unauthorized and untrained personnel
• storage, installation and operation of the measuring equipment outside the specified ambient conditions (see technical
specification)
2.4 Safety instructions for the user
Any work on the transmitter has to be carried out by authorized and qualified personnel. Observe the safety instructions in
the operating instruction. For the technical data of the transmitter, transducers and accessories, see technical specification.
• Observe the safety and accident prevention regulations applicable on the site of operation.
• Only use the supplied mounting fixtures and transducers as well as the intended accessories.
• Always wear the required personal protective equipment.
2.5 Safety instructions for the operator
• The operator shall qualify the personnel to perform their assigned tasks. The operator shall provide the required personal
protective equipment and oblige the personnel to wear it. It is recommended to risk assess the workplace.
• Besides the safety instructions in this operating instruction, the health, safety and environment regulations applicable for
the range of application of the transmitter, transducers and accessories have to be observed.
• With the exceptions stated in chapter 11, the measuring equipment is maintenance-free. Any components and spare
parts may only be replaced by FLEXIM. The operator shall carry out periodic checks for changes or damages that can
present a danger. For further information, contact FLEXIM.
• Observe the specifications for the installation and connection of the transmitter, transducers and accessories (see
chapter 6 and 7).
2.6 Safety instructions for electrical work
• Prior to any work on the transmitter (e.g., installation, dismounting, connection, service and maintenance), the transmit -
ter has to be disconnected from the power supply. It is not sufficient to remove the internal fuse of the instrument (see
section 7.2).
• Electrical work may only be carried out if there is enough space.
• Open the transmitter in safe ambient conditions only (e.g., air humidity < 90 %, no conductive pollution, no explosive
atmosphere). Otherwise, additional protective measures have to be taken.
• The degree of protection of the transmitter is only ensured if all cables are tightly fitted using cable glands and the housing
is firmly screwed.
• The condition and tight fit of the electrical connections have to be checked at regular intervals.
• When connecting the transmitter to the power supply, an appropriate equipment switch according to IEC 60947-1 and
IEC 60947-3 has to be installed as disconnecting device. The equipment switch has to disconnect all live wires. The ground
conductor connection must not be interrupted. The equipment switch has to be easily accessible and clearly marked as a
disconnecting device for the transmitter. It should be located near the transmitter. If the transmitter is used in an explosive
atmosphere, the equipment switch has to be installed outside the explosive atmosphere. If this is not possible, it has to be
installed in the least hazardous area.
• The connection may only be made to networks up to overvoltage category II. When connecting the inputs and outputs as
well as the power supply, observe the installation instructions, in particular the terminal assignment (see chapter 7).
• The front plate must not be removed (see Fig. 2.1). The transmitter does not contain any components to be maintained
by the user. For repair and service work, please contact FLEXIM.
• Observe the safety and accident prevention regulations for electrical systems and equipment.
