6.5 Information about connecting
cables
The diameter of the connections depends on the
current consumption, length of line and the ambi-
ent temperature of the unit. Information concern-
ing the current consumption can be found in the
Technical Data supplied with the particular unit to
be connected.
The following table lists the minimum diameters
of the connections in relation to the current con-
sumption:

7 Installation
7.1 Combining devices safely
Take care when connecting units together or to
parts of other systems as there is always an ele-
ment of risk (e.g. due to leakage currents).
❯
Only connect units when there can be no
question of danger to operator or to patient.
❯
Only connect units when it is safe to do so and
when there is no risk of damage or harm to the
surroundings.
❯
If it is not 100% clear from the unit data sheet
that such connections can be safely made or if
you are in any doubt, always get a suitably
qualified person (e.g. the manufacturer) to ver-
ify that the setup is safe.
