Power Unit Wiring
Please checkthe voltage of the input power so that it does not exceed the permissible window.
Caution
Connecting excessive voltage will damage the drive
Connecting commercial power with the drive’s U, V, W terminals may cause damage. Please
connect the power to the L1, L2, L3 terminals.
Please use the product by connecting shorting pins to the drive’s B, BI terminals. And when using
an external recovery resistance, please connect with the B+, B terminals after removing the
shorting pin, at the standard resistance.

Please construct the system so that the main power (L1, L2, L3) is always supplied after the control
power (C1, C2) is supplied (see “2.4.1 Power Unit Wiring”)
High voltage remains even after the main power is shut off. Please exercise caution.
Danger
Start re-wiring after making sure that the charge lamp is off after shutting off the main power, to
avoid being electrocuted.
The length of the earthing cable should be as short as possible. Too long cables may cause noises
that might cause malfunction.
