PowerFlex 700S Phase II AC Drive User Manual - Publication 20D-UM006G-EN-P – July 2008
Important Common Bus (DC Input) Application Notes
1. If drives without internal precharge are used (Frames 5 & 6 only), then:
– precharge capability must be provided in the system to guard against
possible damage, and
– disconnect switches Must Not be used between the input of the drive
and a common DC bus without the use of an external precharge
device.
2. If drives with internal precharge (Frames 1-6) are used with a disconnect
switch to the common bus, then an auxiliary contact on the disconnect
must be connected to a digital input of the drive. The corresponding
input (parameter 825-830) must be set to “Precharge Enable”. This
provides the proper precharge interlock, guarding against possible
damage to the drive when connected to a common DC bus.

Maximum/minimum sizes that the terminal block will accept - these are not recommendations.
(2)
Apply counter torque to the nut on the other side of terminations when tightening or loosening the terminal bolt in order to avoid damage to the terminal.
(3)
Not all terminals present on all drives.
(4)
Refer to the terminal block label inside the drive.
(5)
If necessary, two wires can be used in parallel to any of these terminals using two lugs.
