Caution
High Overload (HO) and Light Overload (LO) input currents
The input current at the rated operating point - applies for the short-circuit voltage of the line
supply V
supply voltage of 400 V without line a commutating reactor. If a line commutating reactor is
used, the specified values are reduced by between 70 % and 80 %.
Notice
UL certified Fuses must be used
In order that the system is in compliance with UL, UL certified fuses, circiut-breaker or self
protected combination motorcontroller must be used.
