1. Safety information
Safe operation of these products can only be guaranteed if they are properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.13) in compliance with
the operating instructions. General installation and safety instructions for pipeline and plant
construction, as well as the proper use of tools and safety equipment must also be complied with.
1.1 Wiring
Every effort has been made during the design of the positioner to ensure the safety of the user,
but the following precautions must be followed:
i) Ensure correct installation. Safety may be compromised if the installation of the product is
not carried out as specified in this manual.
ii) Wiring should be carried out in accordance with IEC 60364 or equivalent.
iii) Fuses should not be installed in the protective earth conductor. The integrity of the installation
protective earth system must not be compromised by the disconnection or removal of other
equipment.
1.2 Intended use
Referring to the Installation and Maintenance Instructions, product markings and Technical
Information Sheet, check that the product is suitable for the intended use / application.
1.3 Access
Ensure safe access and if necessary a safe working platform (suitably guarded)before attempting
to work on the product. Arrange suitable lifting gear if required.
1.4 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
1.5 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some previous time.
Consider: flammable materials, substances hazardous to health, extremes of temperature.
1.6 Hazardous environment around the product
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of
temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery.
The positioner is suitable for installation in Zone 1 or Zone 2 ( Gas ). The positioner shall not
be used in zone 0.
1.7 The system
Consider the effect on the complete system of the work proposed. Will any proposed action (e.g.
closing isolation valves, electrical isolation) put any other part of the system or any personnel
at risk?
Dangers might include isolation of vents or protective devices or the rendering ineffective of
controls or alarms. Ensure isolation valves are opened and closed progressively to avoid system
shocks.
