WARNING
The instrument must only be installed and commissioned by qualified
personnel.
The instrument is designed for connection to functional and safety
extra low voltage.
The instrument is designed for connection to operate voltage or safety
extra--low voltage.
Electrical safety depends only on the power supply equipment.
Pneumatic actuators exert considerable positioning forces. The safety
precautions of the actuator used must therefore be scrupulously
observed during installation and commissioning in order to prevent
injuries.
We explicitly draw your attention to the necessity of observing safety
regulations regarding operation in zones subject to explosion hazard, if
applicable.
The specifications of the examination certificate valid in your country
must be observed. Laws and regulations valid in your country must be
observed for the electrical installation in explosions hazardous areas.
In Germany these are for example:
-- Working reliability regulations,
-- Regulations for installing electrical equipment in hazardous areas,
DIN EN 60079--14 (in the past VDE 0165, T1).
It should be checked whether the available power supply, insofar as
this is required, is compliant with the power supply specified on the
rating plate and specified in the examination certificate valid in your
country.
Take care to avoid electrostatic discharges within the hazardous area,
such as can arise if a dry cloth is used to clean the positioner in the
plastic housing.
Devices with the protection type "flameproof enclosure" may only be
opened when the power is off.
WARNING
Devices with the protection type "intrinsically safe" lose their certifica-
tion as soon as they are operated with circuits that do not conform to
the specifications laid down in the EC type examination certificate valid
in your country.
The successful and safe operation of this equipment is dependent
upon its proper handling, installation, operation and maintenance.
