NOTE!
Danger of material damage to the compressor stage
as a result of incorrect connection of the power
supply!
In the event of incorrect connection of the power supply,
the compressor stage may be destroyed due to an
incorrectly rotating drive.
- Connect the power in accordance with the circuit
diagram and check the rotating field before starting
the screw compressor.
Prerequisites for correct installation are correctly
dimensioned fuses in the mains supply (person-system
protection) and a suitable main switch (for switching the
supply on and off).
1.
Using the data in the circuit diagram (in the switch cabinet), check
whether the existing mains supply is suitable. Voltage deviations
of more than 10% are not permitted.
2.
Connect the power in accordance with the circuit diagram in-
cluded in the delivery and in accordance with the technical data.
3.
Check that the direction of rotation is to the right by using a rotat-
ing field measurement device.
