Resistor connection
terminals
Normally B2 and B3 are short-circuited.
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.
When using N terminal, make sure not to exceed the fuse's rated
voltage (360 VDC, 60 A).
