Special Notes
1) A 3-phase power supply and an external 1 mF capacitor are mandatory for the UNITROL 1020 to operate within the nominal excitation current range of 15 A to 20 A.
2) For UNITROL 1010 and UNITROL 1020 models, if the machine voltage measurement exceeds 250 VAC, the machine star point must be connected to protective earth (PE).
