Notes on the electrical installation
The generators must be connected to the mains via a disconnecting device, which
itself should be located in the vicinity of the equipment and labelled as the discon-
necting device for said equipment.
The rating of the disconnecting device is derived from the electrical parameters
stated under "Specifications" or from the data on the rating plate.
NOTE
§
When using
external circuit breakers as back-up fuses,
we recommend the use of
tripping characteristic K.
6.3.1
Supply ratings
The mains voltage and frequency must match the nominal values stated in the
manual (or on the rating plate).
6.3.2
Cable quality and cable routing
Always use shielded cables for control or monitoring purposes.
The shielding should be connected to the generator's earth on one side of the
generator.
Avoid laying control cables in the direct vicinity of current-carrying components
or cables.
Shorten any mains cables that are too long to the necessary length. Rolling up
cables can lead to a risk of overheating.
INFO
All connections of the signal and control lines are galvanically
connected to the generator.
