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
Contact with exposed and live elements generate 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, do a PE conductor check.
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.
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 crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
► Keep limbs out of the reach of the roots pump.
WARNING
Risk of explosion when the ignition temperature of the pumped medium is reached
The missing of the prescribed temperature monitoring leads to an ignition in the suction chamber,
once the ignition temperature is reached.
► Always monitor the gas temperature in the fore-vacuum flange in order to safely observe temper-
ature class T3.
► When a gas temperature of 180 °C is reached, switch the roots pump off (zero potential).
