►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 injury.

►Instructions on avoiding property damage

Notes, tips or examples indicate 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 12100 Section 5. Where applica-

ble, all life cycle phases of the product were taken into account.

Risks during transport

WARNING

Danger of serious injury due to falling objects

Due to falling objects there is a risk of injuries to limbs through to broken bones.

►Take particular care and pay special attention when transporting products manually.

►Do not stack the products.

►Wear protective equipment, e.g. safety shoes.

Risks during installation

CAUTION

Danger of injury from moving parts

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.

Safety

8/50

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 vacuum pump

can increase to above 70 °C.

►Provide suitable touch protection.

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 maintenance, decommissioning and in event of malfunctions

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.

Safety

9/50

CAUTION

Danger of injury from moving parts

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.

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.

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.

WARNING

Health hazard and risk of environmental damage from toxic contaminated operating fluid

Toxic process media can cause operating fluid contamination. When changing the operating fluid,

there is a health hazard due to contact with poisonous substances. Illegal disposal of toxic substan-

ces causes environmental damage.

►Wear suitable personal protective equipment when handling these media.

►Dispose of the operating fluid according to locally applicable regulations.

CAUTION

Scalding from hot operating fluid

Danger of burns when draining operating fluid in case of skin contact.

►Wear protective equipment.

►Use a suitable collection receptacle.

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

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 working on it.

►Wear personal protective equipment if necessary.
