Piping must be connected free of stress.
A bellows fitted in the piping will compensate
for any stress arising.
3.6. Cooling
The pumping stations have been designed to be air cooled as
standard where ambient temperatures of up to 35 °C are
involved.
If required, conversion to water cooling is possible (for water
cooling please refer to the "Accessories").
Water cooling is necessary where casing
heating is being used.

3.4. Electrical Connections
The electrical connections must be effected in
accordance with local regulations. The voltage
requirements shown on the rating plate must
comply with the mains voltage.
Alternating current is required for operating the pumping
station.
The mains connection cable (length 2.5 m) is provided on the
pumping station.
➡
Plug in mains connection plug (the pumping station can
now be operated).
Accessory Connections:
For the electrical connections of accessories please refer to
Section 3.7. "Connections Plan".
3.5. Connecting The Vacuum Unit
There should be no unilateral loading on the high
vacuum flange.
The weight of a vacuum chamber freely flanged
on the vacuum flange must not exceed, with the
TSH/TSU 071 maximum 200 N (20 kg), with
TSH/TSU 261 maximum 500 N (50 kg), and with
TSH/TSU 521 maximum 1000 N (100 kg).
The utmost cleanliness must be observed
when fitting all high vacuum parts. Unclean
components prolong the pumping time.
➡
Only remove the blank cover on the high vacuum flange
once the vacuum unit is ready for connection so that no
moisture, which would prolong the pumping time to
attainment of final vacuum, precipitates in the pump.
➡
The use of a splinter shield in the high vacuum flange
protects against foreign bodies (please see accessories
for the turbopump).
Connecting The Pumping Station Via A
Bellows
Advantage:
Reduced vibration transmission.
The pumping station must be mechanically anchored.
➡
Screw the pumping station to a holder with threaded
screws M10. The elastic buffers need not be removed.
