Connection configurations
Connection B - FORE-VACUUM PUMP
A flange KF 25 NW is available to connect the
Turbo-V300 ICE to the fore-vacuum pump. A hose
or vacuum approved pipe can be used. If a rigid
pipe is used, any vibration generated by the me-
chanical pump must be eliminated through the use
of bellows.
NOTE
The Turbo-V300 ICE is characterized by its high
compression ratio also for oil vapors. When using a
mechanical oil-sealed pump, it is advisable to in-
stall a suitable trap between the turbopump and the
fore-vacuum pump in order to prevent oil back-
streaming.
Connection C - ELECTRICAL
The turbopump is connected to the controller
through an 6-pin connector. Pins B, C and D are
the 3-phase supply to the motor, pins A and F are
connected to the temperature sensor (NTC type,
30 KΩ resistance at 25d C) and pin E is connected
to the pump ground.
If the temperature sensor is disconnected, the
pump will not start. To prevent damage to the
pump when the temperature exceeds 60d C, the
sensor automatically cuts out the power supply.
