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.
