WARNING
Danger of cut injuries from unexpected start up.
The use of mating plugs of the electronic drive unit (accessories) enables the automatic run-up of the
vacuum pump as soon the power is turned on. Attaching mating plugs before or during the installa-
tion leads to the movement of parts hence the risk of cut injuries by sharp-edged in the exposed high
vacuum flange.
► Only connect mating plugs after the mechanical installation.
► Only switch on the vacuum pump immediately prior to operation.

Original power supply packs (e.g. TPS 180) and connection cables with blocking diode are available for
the voltage supply to the TC 80 electronic drive unit. The connection cable with blocking diode prevents
power from being fed back into the supply after switching off the turbopump.
