Step 2: Validate the Drive Installation

Step 2: Validate the Drive Installation
It is important that you thoroughly inspect each of your drive installations before applying power for the first time. This is
especially important if you did not personally perform the installation tasks. Satisfy yourself now that each drive is ready to
be energized when you get to
ATTENTION: To avoid an electric shock hazard, the drive must be locked and tagged before continuing Step 2: Validate the Drive
Installation. Failure to comply can result in personal injury and/or equipment damage.

Identify Which Drive You Have

There are two types of PowerFlex 750-Series drives, the PowerFlex 753 and the PowerFlex 755. There are some important
differences between the drives that need to be considered in subsequent steps. If you don't know how to determine what
type of drive you have, see
Drive/Motor Name
(example, Main Exhaust Fan)
Installed Drive

Verify Power Wiring

Visually inspect the power wiring connections to each drive. Be sure you are satisfied that the correct wires are connected to
the input terminals and to the output terminals. See
connections are made.
Verify Wiring
AC input power is on L1, L2, L3 / R, S, T.
Output motor connection is on T1, T2, T3 / U, V, W.
Proper ground wire terminations at PE ground studs.
If equipped, dynamic brake resistor connection is on BR1 and BR2.
If wires are present, go to Dynamic Brake Resistor on page 66
dynamic brake resistor nameplate information.
IMPORTANT Rockwell Automation recommends that XLPE-type cabling be used on output of the drive.
