Note:
The fuse, DC reactor, braking unit, braking resistor, input reactor, input filter, output

reactor and output filter are optional parts. See Appendix D Optional peripheral
accessories.
P1 and (+) have been short connected by default for 160P and higher models. If you need to

connect to external DC reactor, take off the short-contact tag of P1 and (+).
When connecting the braking resistor, take off the yellow warning sign marked with PB,

(+) and (-) on the terminal block before connecting the braking resistor wire, otherwise,
poor contact may occur.
Braking units are optional parts for 055P–075P models, and they can be built in or

externally connected to the models.
