What You Need to Do To install the field board:
❐ Step 1: Remove power from the drive
❐ Step 2: Remove the protective covers
❐ Step 3: Remove the existing field board
❐ Step 4: Install the new field board
❐ Step 5: Replace the protective covers and document the change
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 1: Remove Power
from the Drive
1. Remove and lock-out all incoming power to the drive.
Step 2: Remove the
Protective Covers
1. Loosen, but do not remove, the four hexalobular screws that secure the top
control pan cover to the drive, then slide the cover up and off the drive
chassis (see Figure 1 on page 3). Tightening torque is noted in the
illustration for reassembly.
2. Disconnect the DPI cable from the HIM assembly (if present) (see Figure
1 on page 3).
Important:A communication cable connects the HIM assembly to the
Control board mounted on the control pan. Therefore, the
bottom control pan cover and HIM assembly cannot be fully
removed from the drive until the cable is disconnected. Step 4
details this connection.
3. Loosen, but do not remove, the four hexalobular screws that secure the
bottom control pan cover to the drive, then slide the cover up and off the
drive chassis (see Figure 1 on page 3). Tightening torque is noted in the
illustration for reassembly.
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.

Important: Mark all connections and wires before removal to avoid
incorrect wiring during reassembly.
2. Disconnect the cables from connector XFCD and X3 on the field board.
3. Remove the eleven hexalobular screws that secure the field board to the
control EMI shield and remove the board.

Step 4: Install the New
Field Board
Install the new field board in reverse order of removal as detailed in Step 3:
Remove the Existing Field Board on page 4.
• Inspect the cables that connect to connectors XFCD and X3 on the field
board for burn marks, cracks or a loose connector. If necessary, replace the
existing cables with the new cables provided.
