terminals
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 shorted. If there is high
regenerative energy, remove the short-circuit bar between B2 and
B3 and connect an External Regeneration Resistor between B1
and B2.
