General Notes for Tables 2a and 2b:

1.Minimum current loading for each supply voltage is not less than 4% of the maximum operating current shown.

2.Use separate ground returns for +5V and +12V supplies.

3.Where power is provided to multiple drives from a common supply, carefully consider individual drive power require- ments. Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device.
