R88D-GNA5L-ML2/-GN01L-ML2/-GN02L-ML2/-GN01H-ML2/-GN02H-ML2/-GN04H-ML2:
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-GN04L-ML2/-GN08H-ML2/-GN10H-ML2/-GN15H-ML2:
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 be-
tween B2 and B3 and connect an External Regeneration Resistor between B1 and B2.
