Safety precautions
●
Do not expose any body parts to the vacuum.
●
Observe all safety and accident prevention regulations.
●
Regularly check the proper observance off all safety measures.
●
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.
●
A safe connection to the protective earthing conductor (PE) is recommended (protec-
tion class III).
Duty to inform
Each person involved in the installation, operation or maintenance of the vacuum pump
must read and observe the safety-related parts of these operating instructions.
The operator is obligated to make operating personnel aware of dangers originating
from the vacuum pump, the pumped medium and the entire system.
Installation and operation of accessories
Pfeiffer Vacuum pumps can be equipped with a series of adapted accessories. The in-
stallation, operation and maintenance of connected devices are described in detail in
the operating instructions of the individual components.
For information on order numbers of components, see "Accessories".
Use original accessory parts only.
NOTICE
Checking the safety system against excess rotation speed
To provide the functioning of the integrated safety system for avoiding excess rotation
speed, the pump must run-up from the standstill at least once a year.
Switch off the pump and await the complete standstill (rotation speed = 0 Hz).
Run-up the pump according to this operating instructions.
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 due to lack of power disconnection device as defined in SEMI-S2
Pump and electronic drive unit are not equipped with a power disconnection device. In-
stallation of a user-supplied power disconnection device in accordance with SEMI-S2.
Fit a circuit breaker with an interruption rating of min. 10,000 A.
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 you can disconnect it at any
time.
