AEL3 Electric Linear Actuators
1.2 Safety requirements and electromagnetic compatibility
This product is
marked. It complies with LV Directive 2014/35/EU, EN60730-1,
EN60730-2-14.
This product complies with EMC Directive 2014/30/EU, EN61000-6-2, EN6100-6-4
The product may be exposed to interference above the limits of industrial immunity if:
-
The product or its wiring is located near to a radio transmitter.
-
Excessive electrical noise occurs on the mains supply.
-
Cellular telephones and mobile radios may cause interference if used within approximately
one metre of the product or its wiring. The actual separation necessary will vary according to
the power of the transmitter.
-
Power line protectors (ac) should be installed if mains supply noise is likely.
-
Protectors can combine filtering, suppression, surge and spike arrestors. For a copy of the
declaration of conformity contact Spirax Sarco.
1.3 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information
Sheet, check that the product is suitable for the intended use / application.
i) Check material suitability, pressure and temperature and their maximum and minimum values.
If the maximum operating limits of the product are lower than those of the system in which it
is being fitted, or if malfunction of the product could result in a dangerous over pressure or
over temperature occurrence, ensure a safety device is included in the system to prevent such
over-limit situations.
ii) Determine the correct installation situation.
iii) Spirax Sarco products are not intended to withstand external stresses that may be induced by
any system to which they are fitted. It is the responsibility of the installer to consider these
stresses and take adequate precautions to minimise them.
iv) These actuators are not suitable for use as safety devices according to the pressure equipment
directive 2014/68/EU or the machinery directive 2006/42/EU.
1.4 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.
1.5 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
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.
Do not use the actuators in explosive atmosphere according the ATEX directive 2014/34/EU.
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 turned on and off in a gradual way to avoid system
shocks.
1.8 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.
1.9 Temperature
Allow time for temperature to normalise after isolation to avoid danger of burns.
1.10 Tools and consumables
Before starting work ensure that you have suitable tools and / or consumables available. Use only
genuine Spirax Sarco replacement parts.
1.11 Protective clothing
Consider whether you and/or others in the vicinity require any protective clothing to protect
against the hazards of, for example, chemicals, high / low temperature, radiation, noise, falling
objects, and dangers to eyes and face.
1.12 Permits to work
All work must be carried out or be supervised by a suitably competent person. Installation and
operating personnel should be trained in the correct use of the product according to the Installation
and Maintenance Instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where there is no such
system, it is recommended that a responsible person should know what work is going on and,
where necessary, arrange to have an assistant whose primary responsibility is safety.
Post 'warning notices' if necessary.
1.13 Handling
Manual handling of large and/or heavy products may present a risk of injury. Lifting, pushing,
pulling, carrying or supporting a load by bodily force can cause injury particularly to the back.
You are advised to assess the risks taking into account the task, the individual, the load and the
working environment and use the appropriate handling method depending on the circumstances
of the work being done.
1.14 Residual hazards
In normal use the external surface of the product may be very hot. If used at the maximum
permitted operating conditions the surface temperature of some products may reach temperatures
of 90°C (194°F).
Many products are not self-draining. Take due care when dismantling or removing the product from
an installation (refer to 'Maintenance instructions').
