Wiring 4.2 P E 4.2.1 Wiring of the Main Circuit DANGER: The frequency inverter must always be powered off completely before performing any wiring work. Before starting rewiring or other work after performing operation once, check the voltage with a meter etc. more than 10 minutes after power-off. For some time after power-off, there is a dangerous voltage in the capacitor. CAUTION: The inverter must be grounded using the dedicated ground terminal.

Protective Functions Error message Display FR-PU04 Meaning Display FR-PA02-02 Description Remedy A) The integrated brake transistor does not operate properly. B) Possibly, a thermal overload occured. Check the relative operating time of the brake resistor. In case of thermal difficulties use an external brake resistor or an inverter of higher capacity. Br. Cct.
Protective Functions Error message Display FR-PU04 OL oL UFU 26 Meaning Display FR-PA02-02 Description Remedy Overcurrent during acceleration If a current of more than 150% of the rated inverter current flows in the motor, this function stops the increase of the frequency until the overload current reduces to prevent the inve r t e r f r o m r e s u l t i n g i n overcurrent shut-off. When the overload current has reduced below 150%, this function increases the frequency again.
