R88D-KTA5L/-KT01L/-KT02L/-KT01H/-KT02H/-KT04H:
Normally, do not short B1 and B2. Doing so may cause malfunctions.
If there is high regenerative energy, connect an External
Regeneration Resistor between B1 and B2.
R88D-KT04L/-KT08H/-KT10H/-KT15H:
Normally B2 and B3 are shorted. Do not short B1 and B2. Doing so
may cause malfunctions. 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.
