Risks during maintenance
WARNING
Risk of injury from reactive, potentially explosive, or otherwise hazardous gas/air mixtures
during maintenance
Uncontrolled leakage of process gases may result in the formation of explosive gas-air mixtures after
opening the vacuum pump. Ignition can cause very serious injuries.
► Ensure that the suction chamber is sufficiently inert before starting maintenance work.
► Ensure a closed inert gas system in order to avoid zone entrainment as a result of process gas
escaping.
WARNING
Danger to life from electric shock during maintenance and service work
There is a danger to life from electric shock when making contact with live components that still exist
after the vacuum pump has been switched off.
► Disconnect the vacuum pump safely from the mains.
► Wait until the vacuum pump comes to a standstill (rotation speed = 0).
► After switching off the vacuum pump, wait another 5 minutes until the capacitors have dis-
charged.
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
► Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
► Decontaminate affected parts before carrying out maintenance work.
► Wear protective equipment.
WARNING
Crushing and cutting danger on unprotected parts from unforeseeable automatic run-up dur-
ing maintenance.
During activities on exposed mechanical components, there is a risk of crushing or cut injuries from
sudden run-up.
► Switch off the vacuum pump before any maintenance work and work.
► Vent the vacuum pump to atmospheric pressure.
► Disconnect the vacuum pump safely from the mains.
► Secure the vacuum pump against re-start.
► Disconnect the mains cable from the vacuum pump.
Risks in the event of malfunctions
WARNING
Danger to life from electric shock in the event of a fault
In the event of a fault, devices connected to the mains may be live. There is a danger to life from
electric shock when making contact with live components.
► Always keep the mains connection freely accessible so you can disconnect it at any time.
