Which of the following can be used to start the inverter of the UPS5000-H?

Starting the inverter is a fundamental control operation for the UPS5000-H. This action can be performed through the primary user interfaces designed for direct equipment control. The UPS LCD (Liquid Crystal Display) provides local, on-site control for all major functions, including inverter startup. The UPS WebUI provides the same level of control remotely over a network connection via a web browser. Both are standard, documented methods for managing the UPS's operational state.

B. ECC is not a standard Huawei management tool for the UPS5000-H and is not a valid interface for controlling the inverter.

D. NetEco is a high-level Data Center Infrastructure Management (DCIM) system. While it monitors the UPS, direct, low-level control actions like starting an inverter are typically performed via the device's dedicated interfaces (LCD/WebUI).

1. Huawei UPS5000-H (800-1600 kVA) User Manual. Section: "Operating the UPS > Startup > Starting the Inverter". This section provides step-by-step instructions for starting the inverter using both the LCD and the WebUI, explicitly confirming these two methods.

2. Huawei UPS5000-H (800-1600 kVA) Communication Protocol. This document details the commands and objects available for remote management, which are utilized by the WebUI and other management systems. It distinguishes between monitoring parameters (read by NetEco) and control commands (executed via WebUI/LCD).
