PowerFlex® DC Drive Frame D AC Current Transducers

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.

❐ Step 2: Remove the protective covers and open the control panel

❐ Step 3: Remove the existing AC current transducers

❐ Step 4: Install the new AC current transducers

❐ Step 5: Close the control panel, replace the covers and document the

change

Step 1: Remove Power from the Drive

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:

• 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.

Step 2: Remove the Protective Covers and Open the Control Panel

1. Loosen, but do not remove, the four hexalobular screws that secure the top

protective cover to the drive, then slide the cover up and off the drive chassis. Tightening torque is noted in the illustration for reassembly.

2. Loosen, but do not remove, the six hexalobular screws that secure the top air

flow plate to the drive, then slide the plate forward to lift it off the screws. Tightening torque is noted in the illustration for reassembly.

Note: The air flow plate cannot be removed from the drive unless the AC input wiring and bus bar extensions (if installed) are removed. However, the plate must be removed to remove the AC input terminals below it.
