2 Safety

2.1 General safety information

The following 4 risk levels and 1 information level are taken into account in this document.

DANGER

Immediately pending danger

Indicates an immediately pending danger that will result in death or serious injury if not observed.

►Instructions to avoid the danger situation

WARNING

Potential pending danger

Indicates a pending danger that could result in death or serious injury if not observed.

►Instructions to avoid the danger situation

CAUTION

Potential pending danger

Indicates a pending danger that could result in minor injuries if not observed.

►Instructions to avoid the danger situation

NOTICE

Danger of damage to property

Is used to highlight actions that are not associated with personal injury.

►Instructions to avoid damage to property

Notes, tips or examples indicate important information about the product or about this docu-

ment.

2.2 Safety instructions

All safety instructions in this document are based on the results of the risk assessment carried out in

accordance with Low Voltage Directive 2014/35/EU. Where applicable, all life cycle phases of the prod-

uct were taken into account.

Risks during installation

DANGER

Danger to life from electric shock

Power supply packs that are not specified or are not approved will lead to severe injury to death.

►Make sure that the power supply pack meets the requirements for double isolation between

mains input voltage and output voltage, in accordance with IEC 61010-1 IEC 60950-1 and

IEC 62368-1.

►Make sure that the power supply pack meets the requirements in accordance with IEC 61010-1

IEC 60950-1 and IEC 62368-1.

►Where possible, use original power supply packs or only power supply packs that correspond

with the applicable safety regulations.

Safety

9/48

DANGER

Danger to life from electric shock

When establishing the voltages that exceed the specified safety extra-low voltage (according to IEC

60449 and VDE 0100), the insulating measures will be destroyed. There is a danger to life from elec-

tric shock at the communication interfaces.

►Connect only suitable devices to the bus system.

WARNING

Risk of injury due to incorrect installation

Dangerous situations may arise from unsafe or incorrect installation.

►Do not carry out your own conversions or modifications on the unit.

►Ensure the integration into an Emergency Off safety circuit.

Risks in the event of malfunctions

WARNING

Risk of injury from parts moving after a power failure or troubleshooting

The "pumping station" function of the electronic drive unit will remain active after a power failure or if

errors occur that shut down the vacuum pump or the system. When power is restored or after ac-

knowledging a fault, the vacuum pump runs up automatically. There is a risk of injury to fingers and

hands if they enter the operating range of rotating parts.

►Always keep the mains connection freely accessible so you can disconnect it at any time.

►Remove present mating plugs or bridges from the electronic drive unit possibly before the mains

power returns, as these can cause an automatic run-up.

►Switch the pump off using the "Pumping station" function (parameter [P:010]).

2.3 Safety precautions

Duty to provide information on potential dangers

The product holder or user is obliged to make all operating personnel aware of dangers

posed by this product.

Every person who is involved in the installation, operation or maintenance of the product

must read, understand and adhere to the safety-related parts of this document.

Infringement of conformity due to modifications to the product

The Declaration of Conformity from the manufacturer is no longer valid if the operator

changes the original product or installs additional equipment.

●Following the installation into a system, the operator is required to check and re-evalu-

ate the conformity of the overall system in the context of the relevant European Direc-

tives, before commissioning that system.

General safety precautions when handling the product

►Use only power supply packs that comply with the applicable safety regulations.

►Observe all applicable safety and accident prevention regulations.

►Check that all safety measures are observed at regular intervals.

►Recommendation: Establish a secure connection to the earthed conductor (PE); protection class

III.

►Never disconnect plug connections during operation.

►Keep lines and cables away from hot surfaces (> 70 °C).

►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.

►Observe the protection class by ensuring the correct seating of the present sealing plugs.

►Disconnect the electronic drive unit only once everything has come to a complete standstill and

when the mains power supply of the turbopump is interrupted.
