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 25° 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 60° C, the
sensor automatically cuts out the power supply.
