Safety precautions
●
Power supply:
The turbopump power supply must apply to the requirements of dou-
ble insulation between mains input voltage and operating voltage according to the reg-
ulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recommends to use
exclusively original-power packs and -accessories. Only in this case Pfeiffer Vacuum
is able to guarantee the compliance of the European and North American guidelines.
●
Observe all safety and accident prevention regulations.
●
A safe connection to the protective earthing conductor (PE) is recommended (protec-
tion class III).
●
Regularly check the proper observance of all safety measures.
●
Before carrying out any work disconnect the unit and all associated installations safely
from the mains.
●
Do not loosen any plug connection during operations.
●
The unit has been accredited with protection class IP 30. Take necessary measures
when installing into ambient conditions, which afford other protection classes.
●
Keep leads and cables well away from hot surfaces (> 70 °C).
●
Only separate the pump and the electronic drive unit from each other after disconnect-
ing the supply voltage and the complete standstill of the pump.
Duty to inform
Each person involved in the installation or operation of the unit must read and observe
the safety-related parts of these operating instuctions.
The operator is obligated to make operating personnel aware of dangers originating
from the unit or the entire system.
WARNING
Danger of unsafe electrical installation
Safe operation after installation is the responsibility of the operator.
Do not independently modify or change the pump and electrical equipment.
Make sure that the system is integrated in an emergency off safety circuit.
Consult Pfeiffer Vacuum for special requirements.
WARNING
Danger of electric shock
In case of defect, the parts connected to the mains supply are under voltage.
Always keep the mains connection freely accessible so that you can disconnect it at
any time.
