3.3.5 Failure liability

Gefran bears no responsibility for any failures or damaged caused to the inverter if the
recommendations in this instruction manual have not been followed specifically points
listed below.
 If a correctly rated fuse or circuit breaker has not been installed between the power
source and the inverter.
 If a magnetic contactor, a phase capacitor, burst absorber and LC or RC circuits have
been connected between the inverter and the motor.
 If an incorrectly rated three-phase squirrel cage induction motor has been used.
Note:
When one inverter is driving several motors, the total current of all motors running
simultaneously must be less than the rated current of the inverter, and each motor
has to be equipped with a correctly rated thermal overload relay.
