B1
External regenera-

30 to 400 W: This terminal does not normally need to be connected. If
regenerative energy is high, connect an External Regeneration Resistor be-
tween B1 and B2.
B2
connection termi-
nal
tween B1 and B2.
450 W to 5 kW: Short-circuit between B2 and B3. If regenerative energy is
high, remove the short bar between B2 and B3 and connect an External
Regeneration Resistor between B1 and B2
B3
Regeneration Resistor between B1 and B2.
6 to 15 kW: Connect an External Regeneration Resistance Unit between B1
and B2.
U
