RGU™ Isolation Board Replacement 5
Installing the Isolation Board 1. Secure the burden resistors in the terminals on the new board (verify that
the clear insulation does not enter the terminals). Torque to 6 lb-in
(0.7 N-m).
Note: TB2 is only used in Series B RGUs (see the data nameplate).
2. Place the board on the six standoffs and secure the board.
3. Connect terminal blocks TB5 and TB6 to the isolation board. The
terminal blocks must be firmly pressed into the appropriate sockets.
4. Connect the feedback connection to J1, the ribbon cable to J2, the
current transducer connection to J7, and the PE ground wire to P1.
5. Replace the Lexan guard to the isolation board.
6. Verify that SW1 is set appropriately (115V AC).
Concluding Steps After installing the isolation board, replace all Lexan shielding and secure
the bay door. Send the board to Rockwell Automation for repair, or dispose
of the old board according to your company’s procedures and local
ordinances.

ATTENTION: SW1 must be set to the appropriate control
power. Setting SW1 to the wrong setting will result in damage
to the isolation board and other components.
