Replace the Lexan shield to the isolation panel
Verify that SW1 is set correctly (115V AC). At the end of the step, replace all Lexan shields and secure the compartment door after installing the isolation panel. Send the circuit board to the automation company for maintenance, or dispose of the old circuit board according to your company's procedures and local regulations! Note: SW1 must be set to the appropriate control power. Setting SW1 to the wrong setting will cause damage to the isolation panel and other components.

Please confirm that you have received the corresponding item in publication 2364F-5.13, June 1999 Replacement Kit Instructions RGU ? Isolation board replacement content This document describes how to remove and replace the isolation board and load resistor in the regenerative DC bus power supply unit (RGU). Use the following table to verify that you have received the corresponding items in the toolkit.
If you received a closeout kit:
If you have received a load resistor kit: Note: Refer to Table a to verify that you have received the appropriate load resistor kit. Other items required Before starting, please ensure that you also have the following tools: ? Tools you need: – Measuring voltage – Removing, loosening and tightening screws (including terminal screws) – Tightening screws (6 lb in/0.7 N-m) ? Documents: – Schematic diagram of your drive system – Publication 2364F-5.01, Regenerative DC bus power supply unit (RGU) - User's manual Note: If the existing load resistor is damaged, You need to order the appropriate resistor kit (see Table A on page 4). For this part: you should receive this quantity: isolation board 1 ESD wrist strap 1 For this part, you should receive the following quantity: load resistor 2 (for A series RGUs) 3 (for B series RGUs) publication 2364F-5.13 June 1999 2 RGUs ? Safety precautions for the replacement of isolation plate When repairing the RGU or drive system, the following general precautions apply: Special instructions Important: You need to reuse the parts removed from the device. Place the parts on a clean surface in the order they were removed!
