4.8.1
INTAKE AND OUTLET CONNECTION
All the turbine's openings are protected in order to prevent extraneous parts entering it. Only remove these
protections positioned on the intake and outlet points shortly before connecting to the user system.
WARNING
It is possible to use the side channel turbine as compressor ONLY for permitted pressures (see
3.3).
WARNING
If the need arises to reduce the side channel turbine load, install a derivation valve instead of
narrowing the intake or outlet.
The user system connection (both intake and outlet) must be performed with pipes with a diameter equal to or
greater than the turbine's intake and/or outlet opening.
The weight of pipes or any expansions must not burden the turbine connections.
We recommend you carry out the final connection to the turbine using flexible pipes or fittings, thus avoiding rigid
connections that can induce tensions and cause harmful vibrations.
It is important to tighten all pipes and couplings.
Extremely long piping or one with a diameter that is too small and with tight, regular curves reduces the turbine's
performance.
HAZARD
Make sure that the turbine's discharged gases are released from the workplace. These must be
treated in such a way as not to contaminate the work environment and surrounding atmosphere.
WARNING
Make sure that vibrations or loads are not transmitted on the turbine's attachments.
WARNING
Use an intake filter, especially if the turbine works with unclean air flows.
4.8.2
ELECTRIC CONNECTION
WARNING
Check that voltage and frequency correspond to values contained on the motor plate.
A voltage deviation is allowed with respect to the nominal value of ± 5%.
The connection cable must be in line with the power absorbed by the motor from the turbine (the turbine's
absorption levels are shown on the electric motor plate and in the tables in point 3.3 of this manual) bearing in
mind the environmental operating conditions.
Use the cable clamp openings to pass the power cables inside the terminal board.
HAZARD
Always earth the turbine. Always connect the earth cable to the relative clamp before connecting
to the mains supply and check the dispersion capacity.
HAZARD
Lay the side channel turbine power cable in such a way that it cannot cause the risk of tripping or
falling or can be damaged.
Always install an electric protection system between the turbine and power supply; the turbine's absorption levels
are shown on the electric motor plate and on the tables in point 3.3 of this manual.
The fuses do not protect the motor, but are only a protection against short-circuiting. Select a suitable kind and
size of fuses bearing in mind the peak current, especially in the case of direct start-up.
The protection with motor protection is essential against overloading risks, in the absence of a network phase,
excessive variation of the voltage or turbine block. Adjust the motor protection on the plate's nominal current as
the maximum level.
