f Braking resistor terminals, P(+) and DB
1) Connect terminals P and DB of a braking resistor to terminals P(+) and DB on the main circuit
terminal block. (For the braking resistor built-in type, refer to the next page.)
2) When using an external braking resistor, arrange the inverter and braking resistor to keep the
wiring length to 5 m or less and twist the two wires or route them together in parallel.
Never insert a braking resistor between terminals P(+) and N(-), P1 and N(-), P(+) and P1, DB
and N(-), or P1 and DB.
Doing so could cause fire.

Connection without
DC Reactor
When a DC reactor is not to be connected together with
the braking resistor
1) Remove the screws from terminals P1 and P(+), together
with the jumper bar.
2) Put the wire from terminal P of the braking resistor and the
jumper bar on terminal P(+) in this order, then secure them
with the screw removed in 1) above.
3) Tighten the screw on terminal P1.
4) Connect the wire from terminal DB of the braking resistor to
the DB of the inverter.

Connection with DC
Reactor
When connecting a DC reactor together with the braking
resistor
1) Remove the screw from terminal P(+).
2) Overlap the DC reactor wire and braking resistor wire (P)
as shown at left and then secure them to terminal P(+) of
the inverter with the screw.
3) Connect the wire from terminal DB of the braking resistor to
terminal DB of the inverter.
4) Do not use the jumper bar.
g DC link circuit terminals, P (+) and N (-)
These are provided for the DC bus link circuit system. Connect these terminals with terminals P(+)
and N (-) of other inverters.
Consult IMO if these terminals are to be used.
