z Ƽ indicates the main circuit terminal, and ż indicates the control circuit terminal.
z The models of 30 kW or below have a built-in braking unit as standard, and no external braking unit
is required.
z The models of 7.5 kW to 55 kW have a built-in DC reactor as standard.
z Select a proper braking resistor based on actual requirements. For details, see the preceding
braking resistor selection guideline.
