5.9 Connect to mains power supply
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
► Before the installation, check that the connection leads are voltage-free.
► Make sure that electrical installations are only carried out by qualified electricians.
► Provide adequate grounding for the device.
► After connection work, carry out an earthed conductor check.
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.
