5.5 Connecting to mains power supply
DANGER
Danger to life from electric shock
Inadequate or incorrect grounding of the unit leads to contact-sensitive voltage on the housing. When
making contact, increased leakage currents will cause a life-threatening electric shock.
► Before the installation, check that the connection leads are voltage-free.
► Conduct the electrical connection in accordance with locally applicable regulations.
► Make sure that the local mains voltage and frequency match rating plate specifications.
► Make sure that the mains cable and extension cable meet the requirements for double isolation
between input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.
► Use only a 3-pin mains cable and extension cable with properly connected protective earthing
(earthed conductor).
► Plug the mains plug into a socket with earthing contact only.
► Always connect the mains cable prior to all other cables, to ensure continuous protective earth-
ing.
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.
CAUTION
Risk of injury from trapping of body parts due to unexpected automatic startup
With open control input, the motor can start unexpectedly following extrinsic contact, if the mains volt-
age is already applied.
A risk exists of minor injury to fingers and hands (e.g., hematoma), from direct contact with the vac-
uum flange.
► Note the prescribed switch-on procedure for safe startup.
