Replacement content This document describes how to remove and replace the precharge resistor in the Regenerative DC Bus Power Supply Unit (RGU). Contents of this kit Use the following table to confirm that you have received the corresponding items in the kit: Before starting other required items, make sure that you also have the following tools: Measure voltage – Remove, loosen and tighten screws – Remove, loosen, and tighten nuts – Tighten screws and nuts (10 to 75 lb in/1.0 to 8.5 N-m) Document: – Schematic diagram of your drive system – Publication 2364F-5.01, Regenerative DC Bus Power Supply Unit (RGU) - User's Manual For this section: You should receive the following quantities: precharge resistor One 6 ohm resistor (2364-SPK03B) or two 27 ohm resistors (3664-SPK02A) * * Only old J code RGUs with 27 ohm resistors will use kit 2364-SPK02A.
Notes apply:
Safety Precautions for Replacement of Precharge Resistor 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. IMPORTANT: Some washers, such as clamps and Belleville washers, have only one correct orientation! Note: Only personnel familiar with the drive system, products used in the system and related machinery can plan or implement the installation, startup and future maintenance of the system. Failure to comply may result in personal injury and/or equipment damage. NOTE: Confirm that all AC and DC power supplies are de energized, locked out, or tagged out in accordance with ANSI/NFPA 70E, Part II. Note: The system may contain energy storage devices. To avoid the danger of electric shock, before attempting to repair, repair or disassemble the drive system or its components, please confirm that all voltages on the capacitor have been discharged.
