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.
CAUTION
Danger of burns on hot surfaces
In the event of a fault, the surface temperature of the vacuum pump can increase to above 105 °C.
► Allow the vacuum pump to cool down before carrying out any work.
► Wear personal protective equipment if necessary.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.

uum or leads to bearing damage.
► During disassembly, keep the existing spacer disks separate per installation location.
► Reinstall the same number of original spacer disks per diaphragm head.
NOTICE
Property damage from electrostatic discharge
Neglecting the electrostatic hazard for electronic components results in their damage or destruction
► Implement ESD safety measures at the workstation.
► Observe EN 61340 "Protection of electronic devices from electrostatic phenomena".
Risks during disposal
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.
