Power Wiring
Refer to the information in the
PowerFlex 750-Series AC Drive Installation
Instructions (publication 750-IN001) to wire power to the PowerFlex 755 with
OEM Liquid Cooling Frame 6 and 7 AC drives. However, see
for the
recommended AC line input protection devices to use instead of the protection
devices listed for the standard, air-cooled PowerFlex 755 Frame 6 and 7 drives in
the
PowerFlex 750-Series AC Drives Technical Data (publication 750-TD001).
