1. The terminal configuration varies depend on the model number. Please refer to the ' 1.7 Power terminals' .
2. Analog output voltage is adjustable up to 12V.
3. Analog speed command may be set by Voltage, Current or both.
4. The Common Busbar between P1/L1
5. 1 ~ 10 HP inverters have built-in braking circuit. Braking resistors are only included for 1 ~ 5HP inverters.
15~30HP inverters have built-in DB unit.
