10 Decommissioning
The work described in this section is to be
performed only by personnel appropriately
qualied to carry out such tasks.
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure
equipment that may burst when handled
incorrectly. Flying projectile fragments or the
release of process medium under pressure
can cause serious injury or even death.
Before working on the regulator:
Î Depressurize all plant sections concerned
and the regulator.
Î Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of fatal injury due to electric shock.
Î Upon installation of the electric cables,
you are required to observe the regula-
tions concerning low-voltage installations
according to DINVDE0100 as well as
the regulations of your local power sup-
plier.
Î Use a suitable voltage supply which
guarantees that no dangerous voltages
reach the device in normal operation or
in the event of a fault in the system or
any other system parts.
DANGER
!
DANGER
!
Î Only perform the electrical connection
after switching off the supply voltage.
Make sure the supply voltage cannot be
switched on again unintentionally.
Observe the relevant safety regulations on
mounting or removing the electric actuator.
Before removing the electric actuator from
the valve, disconnect the power supply and
protect it against inadvertent reconnection.
Risk of burn injuries due to hot or cold
components and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
ries.
Î Allow components and pipelines to cool
down or warm up to the ambient tem-
perature.
Î Wear protective clothing and safety
gloves.
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Î Do not loosen the control line while the
valve is pressurized.
