- If flexible stranded cables with their total cross-sectional area assembled from
several fine filaments are used for the connections, ferrules must be crimped
onto their ends. It must be ensured that no individual filament has been left out
of the ferrule.
When work is carried out on the connecting cables and the instrument terminals,
it is possible that live components may be touched inadvertently. If this occurs,
the voltage present may be injurious to health or may even have fatal consequen-
ces.
The risk to life and limb can be significantly reduced by observing the above
safety precautions.
NOTE!
The instrument can be damaged by incorrect operation.
- Only the specified and appropriate voltages and signals may be connected to
the respective terminals and ports provided for them.
- The cross-sectional areas of all cables used must be adequate for the purpose.
- The required cable types are specified in
[Section 2 Technical Data]
.
If any incorrect cables, voltages or signals are applied to the terminals, this can
result in damage to the PQM 1588 and the electrical installation.
DANGER!
To avoid accidents, the following must be observed:
At the PQM 1588 installation site (e.g. control cabinet, enclosure), all wires and
stranded cables must be adequately secured or grouped in harnesses.
If the above safety precautions are taken, the risk of damaging equipment and
assets or endangering life and limb can be significantly reduced.
NOTE!
If flexible stranded cables are used for the connections, insulated ‘short’ ferrules
6 mm in length must be crimped onto their ends. When necessary, longer ferrules
must be shortened to a length of 6 mm after crimping.

DANGER!
To avoid accidents, the following must be observed:
- The safety instructions in
[Section 5.1 Elektrical connections]
.
- Connection of the instrument power supply as specified in this manual
