Configuration ● SM: standard configuration type ● FM: full configuration Cable routing Routed from the top (only the UPS5000-E-300K-SMT model contains "T") This document describes the following UPS models: ● UPS5000-E-200K-SM/FM The models provide four configurations: 50 kVA, 100 kVA, 150 kVA, and 200 kVA.
Page 26: Working Principle
NO TE ● The UPS5000-E-200K-SM supports cable routing from the top or bottom. ● The UPS5000-E-200K-FM supports cable routing from the top and can support cable routing from the bottom if a cable entry cabinet is installed for the non-isolation protection model.
Page 27: Working Modes
In bypass mode, loads are powered by the bypass module. The bypass power supply is not protected by the UPS and therefore is prone to the mains outage, abnormal AC voltage waveform, or abnormal frequency. Issue 15 (2022-01-30) Copyright © Huawei Technologies Co., Ltd.
Page 28: Battery Mode
If the mains input is abnormal or the rectifier becomes abnormal, the UPS transfers to battery mode. The power module obtains DC power from batteries, and the power is converted into AC output by the inverter. Issue 15 (2022-01-30) Copyright © Huawei Technologies Co., Ltd.
Page 29: Maintenance Bypass Mode
2.2.2.4 Maintenance Bypass Mode When the UPS works in maintenance bypass mode, the current flows through the maintenance bypass instead of the power module. You can maintain the circuit inside the cabinet. Issue 15 (2022-01-30) Copyright © Huawei Technologies Co., Ltd.
Page 30: Eco Mode
UPS transfers from bypass mode to inverter mode. In bypass mode or normal mode, the rectifier keeps working and charges batteries using a charger. The ECO mode delivers a high efficiency. Issue 15 (2022-01-30) Copyright © Huawei Technologies Co., Ltd.
