Adjustment and Inspection
1) Check if the rated voltage (Ue) of the starter matches with the actual
control voltage of the power supply.
2) Check if the rated operating current of the motor is within the setting
current range of the starter.
3) Check if the starter can operate normally: Turn the knob of the starter
to 1 and press TEST button, you should hear the starter is disconnected and
the knob should be turned to O. If not, pelase replace the starter.
4 ) The operating current of the starter (setting current value of thermal
element) should be determined based on the rated current of the motor. If
you need to use a setting current value between two scales, you can slightly
turn the cam proportionally and make adjustment during actual operation.

Selection of backup fuse
Protection will be provided by the starter if the short circuit current is
smaller than or equal to the rated limit short circuit breaking capacity of the
starter; if the short circuit current is bigger than the rated limit short circuit
breaking capacity of the starter, proteciton will be provided by fuse or circuit
breaker. See Table 8 for the models and current of the backup fuse of the
starter.
