2 Safety
2.1 General safety instructions
This document includes the following four risk levels and one information level.
DANGER
Imminent danger
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
►Instructions on avoiding the hazardous situation
WARNING
Possibly imminent danger
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
►Instructions on avoiding the hazardous situation
CAUTION
Possibly imminent danger
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
►Instructions on avoiding the hazardous situation
NOTICE
Danger of property damage
Notice is used to address practices not related to physical inrury.
►Instructions on avoiding property damage
Notes, tips or examples identify important information on the product or on this
document.
2.2 Safety instructions
All safety instructions in this document are based on the results of the risk assessment carried out in
accordance with Machinery Directive 2006/42/EC Annex I and EN ISO 12000 Section 5. Where applica-
ble, all life cycle phases of the product were taken into account.
Risks during transport
WARNING
Danger of serious injury from falling or swinging objects
Falling or swinging objects during transport pose a danger of injuries to limbs, up to and including
bone fractures.
►Prevent people from remaining below the suspended load.
►Secure the danger zone if necessary.
►Avoid diagonal pulling of the crane rope.
►Wear protective equipment, e.g. safety shoes.
Safety
8/66

Risks during installation
WARNING
Danger of injury from electric shock
Contact with live parts causes electric shock.
►Make sure that connection leads are voltage-free.
►Make sure that electrical installations are only carried out by qualified electricians.
►Provide adequate grounding for the device.
WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic operating fluid generates toxic vapors. Danger of poisoning if inhaled.
►Observe the application instructions and precautions.
►Do not allow tobacco products to come into contact with the operating fluid.
Risks during operation
WARNING
Danger of poisoning due to emission of toxic process gases from the exhaust
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
►Observe the relevant regulations for handling toxic substances.
►Safely purge toxic process gases via an exhaust line.
►Use suitable filter equipment to separate toxic substances.
CAUTION
Risk of injury from bursting due to high pressure in the exhaust line
Faulty or insufficient exhaust lines cause hazardous situations, e.g. increase in exhaust pressure.
There is a risk of bursting. It is not possible to rule out the risk of injuries due to broken pieces flying
around, high escaping pressure and damage to the equipment.
►Lay the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials of the product.
►Check the exhaust line regularly for correct function.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the pump can rise to
above 70°C.
►Provide suitable touch protection.
Risks during maintenance
WARNING
Danger of injury from strong magnetic field
There is a risk of injury for people with pacemakers and medical implants.
►Make sure that such individuals do not enter the sphere of influence (≤ 2 m) of the magnetic field.
–Identify rooms in which magnetic couplings are openly accessible with the symbol: "No ac-
cess for people with pacemakers"
►Always keep disassembled couplings away from computers, data carriers, and other electronic
components.
Safety
9/66

WARNING
Danger to life from electric shock in the event of a fault
In the event of a fault, parts connected to the mains may be live.
►Always keep the mains connection freely accessible so you can disconnect it at any time.
WARNING
Health risk and environmental damage due to poisoning on toxic contaminated parts or devi-
ces
Toxic process media result in contamination of the devices or parts thereof. During maintenance work
there is a health risk due to contact with these poisonous substances. The non-permitted disposal of
toxic substances results in environmental damage.
►Take appropriate safety precautions and avoid health risks or environmental hazards due to toxic
process media.
►Decontaminate the affected parts before carrying out maintenance work.
►Wear protective equipment.
CAUTION
Scalding from hot operating fluid
Danger of burns when draining operating fluid if it comes into contact with the skin.
►Wear protective equipment.
►Use a suitable collection receptacle.
2.3 Safety precautions
Information requirement on possible hazards
The owner or operator of the product is required to make all operating personnel
aware of hazards arising from the use of this product.
Every person who is involved in the installation, operation or maintenance of the
product must have read and understood the safety-relevant parts of this documen-
tation.
Infringement of EU conformity due to modifications to the product
The Declaration of Conformity from the manufacturer is no longer valid if the opera-
tor changes the original product or installs additional equipment.
●Following installation into a system, the operator is required to check and re-
evaluate as necessary the conformity of the overall system in the context of the
relevant EU Directives before commissioning that system.
General safety precautions when handling the product
►Observe all applicable safety and accident prevention regulations.
►Check that all safety measures are observed at regular intervals.
►Do not expose body parts to the vacuum.
►Always ensure a secure connection to the earthed conductor (PE).
►Never disconnect plug connections during operation.
►Observe the above shutdown procedures.
►Keep lines and cables away from hot surfaces (> 70°C).
►Never fill or operate the unit with cleaning agents or cleaning agent residues.
►Do not carry out your own conversions or modifications on the unit.
►Observe the unit protection class prior to installation or operation in other environments.
►Provide suitable touch protection, if the surface temperature exceeds 70°C.
