WARNING
Risk of danger to life through missing mains disconnection device
The vacuum pump and electronic drive unit are
not
equipped with a mains disconnection device
(mains switch).
► Install a mains disconnection device according to SEMI-S2.
► Install a circuit breaker with an interruption rating of at least 10,000 A.
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.
WARNING
Risk of fatal injury due to electric shock caused by water damage
The device meets protection degree IP 20 according to EN 60529: 2014 and is not protected against
water ingress. Vacuum pumps operated on the floor lead to leakage current in penetrating and sur-
rounding water. There is a danger to life from electric shock when making contact with live water.
► In case of water damage, disconnect the complete power supply from the area affected.
► Provide an on-site electrical fuse protection (e.g. RCD) in hazardous areas.
► When selecting the installation location, observe potential damage from water.
