Digitax HD External 24Vdc Supply

An external 24 Vdc supply is required to power all the low voltage circuits within the drive.

The cable length between the 24 Vdc power supply and the drive should not exceed 10 m.
The 0V connection of the external 24 Vdc power supply should be connected to the same ground connection as the drive. Where this is not possible the 0V connection of the 24 Vdc power supply should be floating.

The working voltage range of the drive 24 V power circuit is as follow:

All Frame Sizes
Nominal operating voltage	24.0 Vdc
Minimum continuous operating voltage	20.4 V
Maximum continuous operating voltage	28.8 V
Minimum start up voltage	20.4 V
Maximum fuse rating	30A
