50 to 400 W: These terminals normally do not need to be connected. 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 connected. If there is high regenerative energy,
remove the short-circuit bar between B2 and B3 and connect an Exter-
nal Regeneration Resistor between B1 and B2.
