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!
The measurement connections L1, L2, L3, N and PE, the instrument power supply
connections L and N, and both alarm contacts must be short-circuited whenever work is
carried out on the instrument.
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 voltage 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.
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.
