WARNING
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.
Electromagnetic compatibility
The electronic drive unit of the vacuum pump complies with the conditions of standard IEC
61000-3-12 stipulating that the permissible short-circuit capacity is observed at the supply
terminal of the customer’s system with the public network.
● Do not install the vacuum pump in living areas as the electronic drive unit does not pro-
vide any protection for the radio reception.
● Ensure that the vacuum pump is connected only to a supply terminal featuring a short-
circuit capacity of
Ssc ≥ 351
.
● If necessary, consult the distribution network operator.
The vacuum pumps are intended for operation only with original electronic drive unit and frequency con-
verter. The respectively valid input voltage range can be seen on the rating plate.
