Three-phase alternating current:
With three-phase alternating current three alternating tensions are carried
across five connections that have a timed relationship to one another, a so-
called phased relationship.

NOTE!
The maximum number of starts per hour may not exceed 10
1.
The motor start-up and current direction should be checked with the
arrow direction on the housing, see figure 4, position 2
CAUTION!
THE PRESSURE CONDUIT MUST NOT BE CONNECTED!
With this start-up the pressure conduit must not be connected. With reverse
flow of the compressor and connected pressure conduit, a vacuum can build up
that can lead to damage to the vanes and actual fracture of the discs.
2.
Connect the pressure conduit at the position 5 in figure 4. Notice: if
the compressor is connected to the application via a conduit in excess
of 3 m in length, we recommend the inclusion of a non-return valve
between the pump and the conduit. This will avoid reverse flow after
shut-down.
3.
A pressure-regulation valve is optional. The regulation of the pressure
is carried out by turning the regulation knob; take note of the indicated
turning direction.
