2.1 Safety precautions
•
Power supply:
The turbopump power supply must apply to the requirements of
double insulation between mains input voltage and operating voltage according
to the regulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recom-
mends 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
(protection class III).
• Regularly check the proper observance off 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 54. When installing into
ambient conditions, which afford other protection classes, the necessary mea-
sures must be taken.
• Keep leads and cables well away from hot surfaces (> 70 °C).
• Only seperate the pump and the electronic drive unit from each other after dis-
connecting the supply voltage and the complete standstill of the pump.
2.2 Proper use
NOTE
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
Ensure safe 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 power supply are under voltage.
Always keep the mains connection freely accessible so you can disconnect it at any
time.
NOTE
CE conformity
The manufacturer's declaration becomes invalid if the operator modifies the original
product or installs additional components!
Following installation into a plant and before commissioning, the operator must
check the entire system for compliance with the valid EU directives and reassess it
accordingly.
