WARNING
Risk of serious injury from swinging, toppling or falling objects
During transport, there is a risk of crushing and impact on swinging, toppling or falling objects. There
is a risk of injuries to limbs, up to and including bone fractures and head injuries.
► Secure the danger zone if necessary.
► Pay attention to the center of gravity of the load during transport.
► Ensure even movements and moderate speeds.
► Observe safe handling of the transport devices.
► Avoid sloping attachment aids.
► Never stack products.
► Wear protective equipment, e.g. safety shoes.
Risks during installation
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements generates an electric shock. Incorrect connection of
the mains supply leads to the risk of live housing parts that can be touched. 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 fatalities due to escaping process media
The manufacturer has no influence on the media being supplied with the vacuum pump. Process me-
dia are often toxic, combustible, potentially explosive and/or reactive in other ways. There is a risk of
serious or even fatal injuries if these media are permitted to leak into the atmosphere.
► Refer to the corresponding local guidelines. This information can be obtained from the Depart-
ment of Health and Safety at Work of the user.
► Prevent zone entrainment.
► Connect the pump outlet to the suction system for hazardous media on the system.
► Perform regular inspections to ensure that there are no leaks at the connection between vacuum
pump and suction pipes.
WARNING
Risk of explosion at increased winding temperature in potentially explosive atmospheres
If the winding temperature of the motor is not monitored, the motor winding could potentially become
a source of ignition. There is a risk of explosion, and consequently the risk of sustaining serious inju-
ries.
► Always establish the connections directed into the motor terminal boxes with a corresponding
PTC thermistor tripping unit of an intrinsically safe electric circuit, suitable for the potentially ex-
plosive area.
– Otherwise, the tripping unit must be installed outside of the potentially explosive area.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
