NOTE
NOTE
Use only the specific cable to connect the inverter to the motor.
Use only the counterpart plugs and sockets for the connection of the
inverter.
The cooling system must always work properly. Avoid obstructions.
The inverter is provided with temperature sensors. Maximum allowable
temperature must not be exceeded (see Chapter 6 and paragrah 11.1.2).
Avoid vibrations and mechanical stresses on the inverter higher than 5g.
A short circuit of one of the three inverter input wires toward ground could
result into an inverter fail.
The cooling system must work properly starting from low speed revolutions.
The inverter is provided with temperature sensors. Maximum allowable
temperature must not be exceeded (see Chapter 6 and paragrah 11.1.2).
A shock absorbing mounting system (for example with silent-block) is
requested in order to reduce mechanical stress on the inverters and keep
maximum vibrations according to paragraph 11.12.3
The system operates correctly with revolution speed ranging from 1400 to
3600rpm. Speed revolutions lower than 1400rpm can not guarantee
adequate
operational
performances.
