Risks during installation
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
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
WARNING
Tilting danger! Serious injury due to tilting of the product
There is a danger of the vacuum pump not attached tipping over due to changes in the center of
gravity or incorrect loading. Serious injuries due to trapping or crushing of limbs, e.g. feet, are the re-
sult.
► Do not use the vacuum pump as a climbing aid.
► Do not exert any force on the product.
► Ensure that the product has a safe centre of gravity, when mounting components.
► Wear protective equipment , e.g. protective shoes
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Dismantle the vacuum pump for inspection, away from the system if necessary.
