Electrical Installation 5-5
Rockwell Automation Publication 22C-IN002E-EN-P - November 2010
Installing the Required External/Separate Input Disconnect
An input disconnect must be installed in the line before the drive input
terminals in accordance with local, national, and international codes, such
as NEC/CEC. If an input disconnect is not installed as a factory option, the
disconnect should be sized according to the in-rush current as well as any
additional loads the disconnect might supply. The trip rating for the in-rush
current (10 to 12 times full load current) should be coordinated with that of
the input isolation transformer, if used.
