10.1 Decommissioning and removal
When decommissioning and removal work is carried out, please note the following:
DANGER!
The following instructions must be observed to prevent danger to life and limb or
damage to equipment and other assets:
- When the instrument is removed, it is essential to switch off the power to the
instrument and the installation beforehand.
- The isolated electrical system must be locked out to prevent its being
inadvertently switched on again.
- All connections must be checked to verify that they are no longer live!
- All live components in the immediate vicinity must be covered to prevent
inadvertent contact.
When work is carried out on the instrument terminals and connecting cables,
there is a risk of live components being touched inadvertently. The working vol-
tage may present a hazard to health or may even be life-threatening.
If the above instructions are followed, the risk of endangering life and limb or
damaging equipment can be significantly reduced.
DANGER!
The following instructions must be observed to prevent danger to life and limb or
damage to equipment and other assets:
- All live cables must be disconnected from the instrument.
- All disconnected cables must be individually isolated and insulated, and
measures must be taken to prevent their inadvertent contact with live
components or electrically conducting parts.
- If it is intended that connecting cables that have been disconnected from the
instrument are to become live again after the instrument has been removed,
adequate measures must be taken to prevent their inadvertent contact with
other live components or electrically conducting parts.
Exposed electrical conductors that can be touched are a hazard to life and limb.
If they come into contact with other electrically conducting components, the
latter can also become live. In addition, cables designated only for low voltages
can carry life-threatening higher voltages if they come into contact with cables at
the supply network voltage.
To prevent this danger to life and limb, the exposed ends of disconnected cables
must be individually insulated in a workmanlike manner. The ends of these cables
must not be joined to each other, and it must be ensured that cable ends cannot
be touched, and that they do not touch each other or other components.
CAUTION!
If the exposed ends of disconnected cables come into contact with each other,
this can result in short circuits and overloading of the installation conductors,
resulting in damage to equipment and other assets.
