Safety advice
3 Safety advice
Depending on the technical circumstances and the time under and at which the electric actuator
is mounted, adjusted and commissioned, in each case you have to take into account particular
safety aspects
If, for example, the actuator actuates a slide in an operational chemical plant, the potential hazards
of commissioning have another dimension from that when this is only being carried out for test
purposes on a „dry“ part of the plant in the assembly room.
Since we do not know the circumstances at the time of mounting / adjusting / commissioning
you may find advice on hazards in the following description which are not relevant to you. Please
observe (only) the advice which applies to your situation!
The actuators must not be put into service until the final machinery into which it is to be incorpo-
rated has been declared in conformity with the provisions of the Directive 2006/42/EC on machin-
ery, where appropriate.
3.1 Personal protection
3.1.1 Safety advice for mounting
We wish to point out expressly that the mounting, the electrical installation and the adjustment
of the actuator NE and the accessories must be carried out only by trained specialised personnel
having mechanical and electrical knowledge.
Switch off all the devices / machines / plant affected by mounting or repair.
If appropriate, isolate the devices / machines / plant from the mains.
Check (for example in chemical plants) whether switching off the devices / machines / plant will
cause potential danger.
If appropriate, in the event of a fault in the actuator (in a plant which is in operation), inform the
shift foreman / safety engineer or the works manager without delay about the fault, in order, for
example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time by
means of suitable measures.
Before mounting or repair, remove the pressure from the pneumatic / hydraulic devices /
machines / plant.
If necessary, set up warning signs in order to prevent the inadvertant starting up of the devices /
machines / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair work.
Check the correct functioning of the safety equipment (for example the emergency push off but-
tons / safety valves, etc).
Before electrical installation of the actuator, check the voltage-free state of all lines to be con-
nected.
