Power Wiring
Make sure that the input power voltage is within the allowed range.
Caution
Overvoltage can damage the drive.
Connection of commercial power to the U, V and W terminals of the drive may cause damage.
Be sure to supply power via terminals L1, L2 and L3.
Connect short-circuit pins to the B and BI terminals. For external regenerative resistance, use
standard resistance for the B+ and B terminals after removing the short-circuit pins.

Configure the system in a way that main power (L1, L2, L3) is supplied only after control power (C1,
C2). (Refer to “Chapter 3 Wiring.”)
High voltage remains for a while, even after the main power is disconnected.
Danger
After disconnecting the main power, make sure that the charge lamp is off before you start
wiring. There is a risk of electric shock.
Grounding must be done over the shortest distance.
A long ground wire is susceptible to noise and thus causes malfunction.
