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 132G/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 045G/055P–055G/075P models, and they can be built in or
externally connected to the models.
