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

ment.
2.2 Safety instructions
Risks during installation
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
►Before the installation, check that the connection leads are voltage-free.
►Make sure that electrical installations are only carried out by qualified electricians.
►Provide adequate grounding for the device.
►After connection work, carry out an earthed conductor check.
DANGER
Danger to life from electric shock
Risk of electric shock when working on the frequency converter and motor. There is a risk to life!
►Make sure that electrical installations are only carried out by trained electricians who are familiar
with the relevant safety instructions for electrical safety and EMC.
Safety
7/44

DANGER
Danger to life from electric shock in case of contact with the frequency converter
High voltages are present at the terminals and inside the frequency converter after disconnecting the
power supply. There is a risk of electric shock if touched.
►Before working on the frequency converter, disconnect the mains cable from the mains power
supply.
►Wait at least 10 minutes after switching off the frequency converter before you start work.
►Provide adequate grounding for the device.
►Prior to installation, check that the connection leads and terminals are voltage-free.
►After connection work, carry out an earthed conductor check.
WARNING
Risk of fatal injury due to electric shock on account of incorrect installation
The device's power supply uses life-threatening voltages. Unsafe or improper installation can lead to
life-threatening situations from electric shocks obtained from working with or on the unit.
►Ensure safe integration into an emergency off safety circuit.
►Do not carry out your own conversions or modifications on the unit.
Risks during operation
CAUTION
Risk of unintentional start-up
Depending on the configured parameter settings, the motor may start up in an uncontrolled manner
when the power supply is switched on. There is a risk of injury to fingers and hands (e.g. hematoma),
in case of direct contact with the vacuum flange.
►Make sure that the motor starting up does not cause a hazardous situation.
►Maintain sufficient distance to the vacuum flange during all work.
Risks during parametrization
DANGER
Danger to life from electric shock
Risk of electric shock when working on the frequency converter and motor. There is a risk to life!
►Make sure that electrical installations are only carried out by trained electricians who are familiar
with the relevant safety instructions for electrical safety and EMC.

►Ensure safe integration into an emergency off safety circuit.
►Do not carry out your own conversions or modifications on the unit.
Avoid electromagnetic interferences
►Ensure that control cables are routed separately from mains cable and motor cable in order to
guarantee immunity to interference.
►Always use shielded cables for analog control circuits where possible.
–Pfeiffer Vacuum recommends EMC cable glands.
►Ensure that no parasitic currents (compensating currents etc.) are permitted to flow through the
shielding of an analog control cable.
►Lay control cables as far as possible from conducting cables.
–Use separate power channels as required.
►In the event of potential cable crossings, maintain an angle of 90° where possible.
►Ensure that switch elements connected upstream, such as contactors and brake coils or switching
elements, remain fault-free whenever these are switched via outputs of the frequency converter.
►Attach the interference suppressor directly to the contactor coils.
–Pfeiffer Vacuum recommends RC-circuitry for alternating current contactors.
►Use freewheeling diodes or varistors for direct current contactors.
