6At power-up, the motor current regulator limits the +12V cur- rent to an average value of less than 4.8A, although instanta- neous peaks may exceed this value. These peaks should measure 5 msec duration or less.

7Minimum current loading for each supply voltage is not less than 4% of the maximum operating current shown.

8Use separate ground returns for +5V and +12V supplies.

9Where power is provided to multiple drives from a common supply, carefully consider individual-drive power requirements. Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device.

10No terminator power. See 11.7.3.4 in the Elite 23 Product Manual.
