ment.

2.2 Safety instructions

Safety instructions according to product’s life stages

All safety instructions in this document are based on the results of a risk assessment.

Pfeiffer Vacuum has taken into account all the relevant life stages of the product.

Safety

10/76

Danger to life due to electric voltage

DANGER

Danger to life due to electric voltage

High voltages are present inside the device. When touching parts that are live, there is a risk of

death. If there is visible damage, there is a risk of death when commissioning the device.

►Work on the open device must only be carried out by trained specialist personnel.

►Before carrying out any installation and maintenance work, switch the device off and disconnect

it from the current supply.

–After switching off, wait about 60 seconds and then disconnect all cables (power cable at the

end).

►Never open the device with the current supply connected.

►Secure the current supply against unauthorized or unintentional reactivation.

►Do not insert any objects into the vent openings.

►Never open an external power supply pack.

►Never operate an open or defective device.

►Secure a defective device against accidental operation.

►Protect the device against moisture.

Disconnect device

The disconnect device must be clearly recognizable by the user and within easy reach.

Fig. 1: Disconnect device in accordance with EN 61010-1

1 Disconnect device

Risks during installation

DANGER

Danger to life from electric shock

The internal earthed conductor is fastened to the housing by a screw. A device without an earthed

conductor attached can be life-threatening in the event of a malfunction.

►Do not rotate or loosen the screw on the internal earthed conductor.

DANGER

Danger to life due to dangerous contact voltage

Voltages above 30 V (AC) or 60 V (DC) are considered dangerous in accordance with IEC 61010. If

you come into contact with dangerous contact voltage, this can result in injury through electric shocks

or even death.

►Only apply protected extra-low voltage (PELV).

Safety

11/76

DANGER

Danger to life from electric shock

Inadequate or incorrect grounding of the unit leads to contact-sensitive voltage on the housing. When

making contact, increased leakage currents will cause a life-threatening electric shock.

►Before the installation, check that the connection leads are voltage-free.

►Conduct the electrical connection in accordance with locally applicable regulations.

►Make sure that the local mains voltage and frequency match rating plate specifications.

►Make sure that the mains cable and extension cable meet the requirements for double isolation

between input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.

►Use only a 3-pin mains cable and extension cable with properly connected protective earthing

(earthed conductor).

►Plug the mains plug into a socket with earthing contact only.

►Always connect the mains cable prior to all other cables, to ensure continuous protective earth-

ing.

Risks during operation

DANGER

Electric shocks due to moisture penetrating into the device

Moisture that has penetrated into the device results in personal injury through electric shocks.

►Only operate the device in a dry environment.

►Operate the device away from fluids and humidity sources.

►Do not switch on the device if fluid has penetrated into it, instead contact Pfeiffer Vacuum Serv-

ice.

►Always disconnect the current supply before cleaning the device.

Risks during maintenance

DANGER

Danger to life due to electric voltage

High voltages are present inside the device. When touching parts that are live, there is a risk of

death. If there is visible damage, there is a risk of death when commissioning the device.

►Before carrying out any installation and maintenance work, switch the device off and disconnect

it from the current supply.

–After switching off, wait about 60 seconds and then disconnect all cables (power cable at the

end).

►Never open the device with the current supply connected.

►Secure the current supply against unauthorized or unintentional reactivation.

►Do not insert any objects into the vent openings.

►Never open an external power supply pack.

►Never operate an open or defective device.

►Secure a defective device against accidental operation.

►Protect the device against moisture.

WARNING

Health hazard through poisoning from toxic contaminated components or devices
