    Foreword This manual is intended to help the user of the 827E to install, test, troubleshoot, and understand the system. If you have any questions or problems, please contact one of the following sources: SERVICE If for any reason further assistance is needed on any power equipment, complete engineering and field service groups are available in Galion, Ohio, to assist you in any way possible.

  • Page 7: Product Information

    Please take a moment when the product is new to fill in this information. This data will allow faster service when calling ABB to order accessories, spare parts, or request field service. First, locate the product information label. This is typically located on the upper front of the equipment frame, or on the rear of the frame.

  • Page 8: Product Description

    Product Description The 827E Inverter System (inverter system) provides AC power output from DC power input. Inverters (inverter modules) work in parallel supporting redundancy (N + 1 or N + X). This enables the system to supply uninterrupted AC power in the event that an inverter fails.

  • Page 9: Table 1 System Configurations

    N+1 output: a system fully populated with inverters where the output of a single redundant inverter is not included. full output: a system fully populated with inverters where the output all inverters is included. Page 9 © Copyright 2021 ABB. All rights reserved.
  • Page 10 A maintenance bypass panel is optional for the 827E. Refer to the J-Drawing (J438827E L51 and L52). The main purpose of the MBP is to allow an AC load to be switched from its primary source (827E Inverter Plant) to an alternate source (AC Line) and back to the primary source (827E Inverter Plant) again.
