Note 1: Connection when using a MCCB with a top coil instead of a MC.
Note 2: A Step-Down transformer is required for 400V/690V models but not for 200V models.
Note 3: As a last resort to prevent fire, be sure to connect a thermal relay (TH-Ry).
Select and connect a thermal relay (TH-Ry) appropriate to the capacity
(Wattage) of the braking resistor.
