PowerFlex® DC Drive and Stand-Alone Regulator (SAR) Control Circuit Board

Installation Instructions

ATTENTION: Only qualified personnel familiar with DC drives and associated machinery should plan or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.

ATTENTION: To avoid an electric shock hazard, ensure that all power to the drive has been removed before performing the following.

ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic Damage” or any other applicable ESD protection handbook.

What You Need to Do

Step 1: Save the Parameter Configuration

Step 2: Remove Power from the Drive

To install the Control board:

❐ Step 1: Save the Parameter Configuration ❐ Step 2: Remove Power from the Drive ❐ Step 3: Remove the Drive Covers ❐ Step 4: Remove the Communication Adapter and EMI Shield ❐ Step 5: Remove the Existing Connections and Option Board(s) ❐ Step 6: Remove the Existing Control Board ❐ Step 7: Install the New Control Board ❐ Step 8: Wire the Control Board ❐ Step 9: Document the Change

If possible, save the drive and adapter parameter configuration to a Human Interface Module (HIM) Set or by up loading the drive and adapter parameters to an offline database file using DriveExecutive™. Refer to the PowerF lex DC Digital Drive User Manual, publication 20P-UM001 the HIM or the on-line Help provided with DriveExecutive.

ATTENTION: Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

, for information on using

• sending an erroneous signal to your system’s field devices, causing unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

Remove and lock-out all incoming power to the drive.

Frame A Drives and the Stand-Alone Regulator

1. Disconnect the Device Peripheral Interface (DPI) cable from the HIM

assembly (if present).

2. Loosen the captive screws that secure the bottom front cover to the drive,

then slide the cover down and off the drive chassis.

1.5 N•m (13.3.lb•in)

3. Press in on the sides at the bottom edge of the top cover and pull the cover

toward you until the cover is partially off the drive chassis. Then pull the top of the cover toward you until the mounting pins align with the keyholes in the top of the cover. Then carefully lift the cover off of the drive chassis.

Important: The HIM assembly is connected to the control board via a

communication cable. Carefully set the top cover down next to the chassis.

4. Continue with Disconnect the HIM Communication Cable

on page 6.

When mounting pins fits in keyhole, lift cover off drive chassis.

Frame B and C Drives

1. Disconnect the DPI cable from the HIM (if present).

2. Loosen, but do not remove, the screws that secure the top and bottom front

covers to the drive, then slide the covers off the drive chassis.

Important: The HIM assembly is connected to the control board via a

communication cable. Carefully set the top cover down next to the chassis.

3. Continue with Disconnect the HIM Communication Cable

Frame D Drives

1. Disconnect the DPI cable from the HIM assembly (if present).

2. Loosen, but do not remove, the four hexalobular screws that secure each of

the three covers to the control pan on the drive, then slide the covers up and off the drive chassis. Tightening torque is noted in the illustration for reassembly.

Important: A communication cable connects the HIM assembly to the

control board mounted on the control pan. Therefore, the middle control pan cover and HIM assembly cannot be fully removed from the drive until the cable is disconnected.

3. Continue with Disconnect the HIM Communication Cable
