5.7.2 Establishing the electric connection
Risk of fatal injury due to electric shock on account of incorrect installation
The device's power supply uses life-threatening voltages. Unsafe or improper installation can lead to
life-threatening situations from electric shocks obtained from working with or on the unit.
► Ensure safe integration into an emergency off safety circuit.
► Do not carry out your own conversions or modifications on the unit.
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.
