7.1 Maintenance instructions
DANGER
Risk of explosion when carrying out installation and maintenance work in potentially explo-
sive areas
There is a risk of explosion if unsuitable tools are used in potentially explosive areas. Ignition can
cause very serious injuries.
► Transport, installation and maintenance work may not be performed in potentially explosive at-
mospheres.
► Always shut down the vacuum pump before commencing any work.
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.
CAUTION
Risk of injury from entrapment of body parts
During installation and maintenance, the motor may start up uncontrolled. There is a risk of minor in-
jury to fingers and hands (e.g. hematoma), from direct contact with the vacuum flange.
► Maintain sufficient distance to the vacuum flange during all work.
► Safely connect the motor to the mains during installation.
► Safely disconnect the motor from the mains prior to maintenance.
► Secure the motor against re-start.
