Warning
This product complies with Electromagnetic Compatibility Directive 2014/30/EU and all its
requirements.
The product may be exposed to interference above the limits of Heavy Industrial Immunity if:
-
The product or its wiring is located near a radio transmitter
-
Excessive electrical noise occurs on the supply. Line protectors can be used with combine
filtering, suppression, surge and spike arrestors.
-
Cellular telephones and mobile radios may cause interference if used within approximately
1 metre (39") of the product or its wiring. The actual separation distance necessar y will vary
according to the surroundings of the installation and the power of the transmitter.
Electrostatic Discharge (ESD) precautions
Static precautions must be observed at all times to avoid damage to the product.
1.2 Access
Ensure saf e access and i f necessar y a safe working plat for m (sui tably guard ed) before at tempting
to work on the product. Arrange suitable lifting gear if required.
1.3 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
1.4 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.
1.5 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.
1.6 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 turned on and off in a gradual way to avoid system
shocks.
1.7 Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure.
Consider double isolation (double block and bleed) and the locking or labelling of closed valves.
Do not assume that the system has depressurised even when the pressure gauge indicates zero.
1.8 Temperature
Allow time for temperature to normalise after isolation to avoid danger of burns.
