2.1 Safety precautions
• Do not loosen any plug connection during operations.
• Wait for the rotor to reach standstill before peforming work on the high vacuum
flange.
• When using sealing gas, the pressure in the hose connection must be limited to
2 bar via an overpressure valve.
• Keep leads and cables well away from hot surfaces (> 70 °C).
• Always ensure a safe connection to the protective earthing conductor (PE, pro-
tection class I).
• Discrete operating of the turbopump and the electronic drive unit is only allo-
wed after authorisation by Pfeiffer Vacuum. In this case the turbopump must be
connected to the PE.
• The danger of an electrical shock in the case of ground leakage must be elimi-
nated immediately (red LED flashes).
• Never fill or operate turbopump with cleaning agent.
2.2 Proper use

• Only operate the turbopump with TC by a specified Pfeiffer Vacuum power sup-
ply. The use of other power units than the intended, is only permitted after con-
sultation with Pfeiffer Vacuum.
• Only operate the turbopump with TC 600 in ambient conditions up to protection
class IP 30.
