In this installation, we use:
- a roughing isolation valve
V1
between the turbo pump and the
roughing pump;
- a high vacuum isolation valve
V2
between the turbo pump and
the chamber to be pumped;
- a relay
K1
, their contacts drive the valve
V1
and the roughing
pump power supply;
- the thermostatic option (MT pump model).
We recommend that you fit a separate earth (ground) conductor to earth
pump. Use an un-insulated braid or a separate insulated green/yellow
conductor with a minimum 9AWG (3mm2) conductor (to comply with US and
Canadian installation codes). Use a screw and a shakeproof washer fitted to
the earth hole from the pump to secure the earth conductor to the pump. The
impedance between the pump-body and the earth connection point must be
< 0.1 Ohm at 25A.
