• If an extension cable is required to connect the transducers to the transmitter, a junction box can be used (optional). Ob-
serve the safety instructions in the user manual. For the technical data of the junction box, see Technical specification.
• Observe the operating conditions, e.g., environment, voltage ranges. For the technical data of the transmitter, transduc-
ers and accessories, see Technical specification.
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 user manual
• use of transmitter, transducer and accessories 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 measuring equipment has to be carried out by authorized and suitably trained personnel. Observe the
safety instructions in the user manual. For the technical data of the transmitter, transducers and accessories, see Techni-
cal 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. They shall provide the required personal protec-
tive equipment and oblige the personnel to wear it. It is recommended to risk assess the workplace.
• Besides the safety instructions in this user manual, 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. If you have any questions, please contact FLEXIM.
• Observe the specifications for the installation and connection of the transmitter, transducers and accessories (see chap-
ter 5 and chapter 6).
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 6.3).
• Electrical work may only be carried out if there is enough space.
• Only open the transmitter in safe ambient conditions (e.g., air humidity < 90 %, no conductive pollution, no explosive at-
mosphere). Otherwise, additional protective measures have to be taken.
• The degree of protection of the transmitter is only ensured if all cables are fitted tight using the cable glands and the
housings are 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 cutoff device according to IEC 60947-1 and IEC
60947-3 has to be installed as disconnector. The cutoff device has to disconnect all live wires. The ground conductor
connection must not be interrupted. The cutoff device has to be easily accessible and clearly marked as a disconnector
for the transmitter. It should be located near the transmitter.

If the transmitter is used in an explosive atmosphere, the cutoff device has to be installed outside the explosive atmo-
sphere. 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.
• 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.
