5 Mounting
5.1 Safety notes
5.2 General
Before mounting
_________________________________________________________________________
The pressure switch is not in conformity with the requirement « Component
equipment with safety function » of the Directive 97/23/CE on the equipment
pressure.
In case of dangerous materials, such as oxygen, acetylene, flammable and
noxious substances, and on the refrigeration systems, tank pressure, etc...,
the regulations corresponding force must be respected.
The national and international precaution and accident prevention regulations
must be observed!
Non-observance of these regulation can cause material damage and bodily
injury!
The plant operator is responsible for the compliance with legal provisions!
Only qualified personnel may work with this device.
_________________________________________________________________________
Before mounting the pressure switch, you must return the installation to
atmospheric pressure!
The operator is responsible for the separation of zones according to the use
and the intrinsic safety of the entire system !
The pressure switch can only be used in environments where the membrane is
sufficiently chemically resistant (corrosion). Otherwise, the switch must be fitted
with a membrane separator whose material is compatible with the medium to be
controlled.
In a hazardous area which can contain dust, mounting the pressure converter
must be "protected against shock!"
It is requires that the electrical connection between pressure converter and
process connection (installation) is guaranteed.
Apart from faulty installation, incorrect settings of the switch can also affect the
proper operation of the process or cause damage.
Therefore, the setting should only be performed by qualified personnel in
accordance with the relevant safety regulations.
_________________________________________________________________________
The mounting location should be easily accessible and as close as possible to
the measurement point; it must be low in vibration.
We must respect the permissible ambient temperature (note to potential thermal
radiation).
The pressure switch can be mounted above or below the point of taking of
pressure.
The nominal position of the unit is vertical. Depending on the configuration of
the measuring point, it is possible to mount it in another position.
