General safety instructions

1  General safety instructions

 

The device must be mounted, started up or serviced by fully trained and 
qualified personnel only; the accepted industry codes and practices are to 
be observed. Make sure employees or third persons are not exposed to any 
danger.

 

All safety instructions and warnings given in these mounting and operating 
instructions, particularly those concerning installation, start-up, and mainte-
nance, must be strictly observed.

 

According to these mounting and operating instructions, trained personnel 
refers to individuals who are able to judge the work they are assigned to 
and recognize possible dangers due to their specialized training, their 
knowledge and experience as well as their knowledge of the applicable 
standards.

 

To ensure appropriate use, only use the device in applications where the op-
erating pressure and temperatures do not exceed the specifications used for 
sizing the device at the ordering stage.

 

The manufacturer does not assume any responsibility for damage caused by 
external forces or any other external factors.

 

Any hazards that could be caused in the regulator by the process medium, 
operating pressure or by moving parts are to be prevented by taking appro-
priate precautions.

 

Proper transport, storage, installation, operation, and maintenance are as-
sumed.

Note:

 Non-electric control valve versions whose bodies are not lined with an in-

sulating material coating do not have their own potential ignition source accord-
ing to the risk assessment stipulated in EN 13463-1: 2009, section 5.2, even in 
the rare incident of an operating fault. Therefore, such valve versions do not fall 
within the scope of Directive 2014/34/EU.
For connection to the equipotential bonding system, observe the requirements 
specified in section 6.3 of EN 60079-14: 2011 (VDE 0165 Part 1).
