Single-Phase Input Power - Frame 7 Only - Allen-Bradley PowerFlex 700 Installation Instructions Manual

PowerFlex 700 Adjustable Frequency AC Drive – Frames 7...10

Other types of shielded cable are available, but the selection of these types can
limit the allowable cable length. Particularly, some of the newer cables bundle 4
conductors of THHN wire and wrap them tightly with a foil shield. This
construction can greatly increase the cable charging current required and reduce
the overall drive performance. Unless specified in the individual distance tables as
tested with the drive, these cables are not recommended and their performance
against the lead length limits supplied is not known. See

Single-Phase Input Power – Frame 7 Only
The PowerFlex 700 drive is typically used with a three-phase input supply. Frame
7 drives have been listed by UL to operate on single-phase input power with the
requirement that the output current is derated by 50% (at maximum ambient
temperature of 25 °C) of the three-phase ratings. Refer to
AC Input Phase Selection
ATTENTION: To avoid a shock hazard, ensure that all power to the drive has
been removed before performing the following.
IMPORTANT Frames 8...10 are not designed for single-phase operation.
Moving the "Line Type" jumper on the Precharge Board (see below) allows single
or three-phase operation.
When selecting single-phase operation, input power must be applied to the R
IMPORTANT
(L1) and S (L2) terminals. This ensures that the fan is properly powered.
