50 to 400 W: Normally, do not short B1 and B2. Doing so may result in
malfunctioning. If there is high regenerative energy, connect an External
Regeneration Resistor between B1 and B2.
750 W to 1.5 kW: Normally B2 and B3 are shorted. Do not short B1 and
B2. Doing so may result in malfunctioning. If there is high regenerative
energy, remove the short bar between B2 and B3 and connect an External
Regeneration Resistor between B1 and B2.
