Warning: high leakage current Earth connection is essential before connecting the input supply (including the AC mains and battery). The UPS must be earthed in accordance with local electrical codes. Earth leakage current exceeds 3.5mA and is less than 3000mA. Transient and steady state earth leakage currents, which may occur when the equipment is started, should be taken into account when selecting instantaneous RCCB or RCD devices.

Chapter 1 Overview This chapter briefly introduces the features, composition, design concept, parallel system, operation mode, battery management and battery protection of the Liebert APM 300 UPS (UPS for short). 1.1 Features The UPS is connected between a critical load (e.g. a computer) and mains power to provide high quality power for the loads.
Chapter 1 Overview Table 1-1 UPS component configuration Component Quantity (pcs) Remark Main power cabinet Standard component Switch cabinet Standard component Bypass module Standard component Power module 1 ~ 10 Mandatory option. Installed at site 1.3 Design Concept 1.3.1 System Design As shown in Figure 1-2, the AC mains source is converted by the rectifier into DC power.
Chapter 1 Overview A manually controlled, maintenance bypass supply is incorporated into the UPS design. It enables the critical load to be powered from the maintenance bypass supply while the UPS is shut down for routine maintenance and repair. Note When the UPS is operating in bypass mode or on maintenance bypass, the connected equipment is not protected from power failures or surges and sags.
Chapter 1 Overview the inverter will shut down. Five minutes later, the inverter will start up automatically. If the short circuit is removed at this point, the load will be transferred back to the inverter. The transfer is determined first of all by the features of the protective device of the system.
Chapter 1 Overview 1.3.5 Battery Circuit Breaker (BCB) The external battery shall be connected to the UPS through the BCB. The BCB box is an option, which shall be installed near the battery. The BCB is closed manually or electrically. The BCB has undervoltage tripping coil. Upon the battery undervoltage, the UPS control circuit will send a signal to the coil to trip the BCB.
Chapter 1 Overview 1.4.2 Parallel System Requirements A UPS system consisting of two paralleled UPS modules behave as if it were one large UPS with the advantage of presenting higher reliability. To ensure that all modules are equally used and to comply with relevant wiring rules, the following requirements apply: 1.

Page 21
Chapter 1 Overview ECO mode As shown in Figure 1-9, in ECO mode, except for the maintenance bypass switch, all power switches and the BCB are closed, the system prefers to put the load on the bypass mains to save energy. When the bypass frequency and voltage are in normal range (settable), the load is supplied by the bypass, with the inverter on standby.
Chapter 1 Overview Common battery mode Common battery function means that in UPS paralleling, the UPS modules can share a battery string to save cost and space and improve efficiency. Note Batteries of different manufacturers, models or used time cannot be used together. Frequency converter mode The UPS can be programmed into frequency converter mode for either 50Hz or 60Hz stable output frequency.
Chapter 1 Overview Trigger: manually through the command of Battery Maintenance Test on LCD or automatically. Interval: 30 days ~ 360 days (default setting: 60 days). 1.6.3 Battery Temperature Compensation The UPS system has battery charge temperature compensation function. When the ambient temperature is increased, the DC bus voltage (which charges the battery) will be reduced correspondingly to provide optimal charging voltage for the battery, thus prolonging the battery service life time.
