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.
WARNING
Risk of injury caused by the turbopump breaking away with the vibration compensator in the
event of a malfunction
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892.
When using a vibration compensator, this will probably lead to the turbopump being sheared off in
use. The energy that this would release could throw the entire turbopump or shattered pieces from its
interior through the surrounding space. Potentially dangerous gases can escape. There is a risk of
very serious injuries, including death, and extensive property damage.
►
Take suitable safety precautions on-site for the compensation of the occurring torques.
►
Before installing a vibration compensator, you must first of all contact Pfeiffer Vacuum.
WARNING
Danger to life from poisoning where toxic process media leak from damaged connections
Sudden twisting of the turbopump in the event of a fault causes fittings to accelerate. There is the risk
of damaging on-site connections (e.g., fore-vacuum line) and resulting leaks. This results in leakage
of process media. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
►
Keep masses connected to the turbopump as low as possible.
►
Use flexible lines to connect to the turbopump where necessary.
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.
WARNING
Risk of danger to life through missing mains disconnection device
The vacuum pump and electronic drive unit are not equipped with a mains disconnection device
(mains switch).
►
Install a mains disconnection device according to SEMI-S2.
►
Install a circuit breaker with an interruption rating of at least 10,000 A.
