SAVCH ELECTRIC shall not be responsible for faults due to the following:
(1) Absence or inapplicable or over large non-fuse breakers was put between the power supply and the
which results in the inverter fault.
(2) Magnetic contactors or advance capacitor or Surge Absorber were connected in series between the inverter and
motor.
● A three phase squirrel-cage induction motor which corresponds with the capacity of the inverter shall be adopted.
● If more than one motors were driven simultaneously by one inverter, the current of these motors when running shall
below capacity of the inverter. And each motor shall be prepared with a thermal relay in appropriate capacity.
● Phase advance capacitors and other capacity elements such as LC or RC shall not be fixed between the inverter
and motor.
4. LIST OF APPLICABLE NO-FUSE BREAKER
The wire size recommended to main circuit terminals is to use single-stranded HIV wire (max. allowable temperature
75℃) under ambient temperature of 40℃. The content in ( ) is the example of single-stranded IV wire (max.
allowable temperature 60℃).
