The installation, operation and maintenance of the FFG-T...EX system must be performed by
expert and authorized personnel only. The required expertise must be obtained by regular training.
It is imperative for operators, installers and servicers to comply with all applicable safety
regulations. This provision shall extend to all local safety and accident preventing regulations not
expressly referred to herein.
Prior to starting operation please check call devices for their proper connection, operability and
power supply; this shall also apply to assemblies coupled thereto.
The general operating instructions of all devices as used must be abided by.
Measures should be taken preventing personal injuries and damage to property from occurring in
case of a defective condition of the FFG-T...EX system.
The FFG-T...EX system must not be operated in the direct vicinity of strong electromagnetic fields
(minimum distance: 1 m).
The FFG-T...EX system must not be exposed to heavy mechanical strain.
The maximum power and voltage values for the intrinsically safe operation as specified in the
assembling and operating instructions should be adhered to.
The safe operation of the system with a view to pressure and temperature of
the materials as employed shall be Operator’s responsibility.
As even in case of failure, the slide tube does not exhibit a source of ignition there
are no objections, in terms of safety, to use the sensor
(float and slide tube) as an
operating unit of the 1 / 2 category with containers for combustible fluids (except for carbon
disulphide and silicon-organic compounds) under varying atmospheric conditions at excess
pressures of up to 25 bar and temperatures of between
–60°C and +250°C.
