    Vertiv™ Liebert® APM Plus User Manual 2.2.2 Bypass Through the intelligent control of the ‘Static Switch’ module (as shown in Figure 2.1 on page 10) containing the controllable electronic switch, the loads can be supplied by the inverter or the bypass. In normal situation, the loads are supplied by the inverter, in that case the automatic inverter switch at inverter side is closed.
  • Page 22 In case of inverter failure and output fuse blowout, the load will automatically transfer to the bypass, and the output power supply will not be interrupted. In this situation, please contact the local customer service center of Vertiv for technical support.

  • Page 26: Parallel System

    Vertiv™ Liebert® APM Plus User Manual 2.3 Parallel System Up to four UPS modules can be parallel-connected to form a parallel system to increase the system capacity and reliability. The load is equally shared between the paralleled UPS modules. Moreover, two UPS modules or parallel system can comprise a dual bus system. Each parallel system has independent output.
  • Page 27 Vertiv™ Liebert® APM Plus User Manual Normal mode As shown in Figure 2.3 below, the mains is rectified by the UPS rectifier and then inverted by the inverter to supply uninterrupted AC power to the loads. At the same time, the charger will charge the battery.
  • Page 28 EOD voltage, if the mains is recovered, the UPS will restart automatically after a certain time of delay. This function and the automatic restart type can be set by the service engineer authorized by Vertiv. During the process of automatic restart time of delay, the UPS will charge the battery to protect against the power-off risk of the load device caused by mains power failure.
  • Page 29 Vertiv™ Liebert® APM Plus User Manual Bypass mode As shown in Figure 2.5 below, in normal mode, in case of an inverter failure, an inverter overload, or an inverter manual shutdown the static switch will transfer the load from the inverter side to bypass side, with no interruption in power to the load.
  • Page 30 Vertiv™ Liebert® APM Plus User Manual ECO mode As shown in Figure 2.7 below, if ECO mode is selected, all the power switches and the battery switches are closed except for the maintenance bypass switch, and the system prefers to put the load on the bypass, to achieve the aim of energy-saving.

  • Page 31: Battery Management

    For the operation principle diagram of the LBS mode, see Figure 8.5 on page 149 and Figure 8.6 on page 150. 2.5 Battery Management The following battery management functions are set by the service engineer through the Vertiv firmware setting. 2.5.1 Normal Function Constant current boost charge Adopt the constant current (within battery charging limit) to charge the battery.

  • Page 32: Advanced Function

    9. Maximum boost charge protection time To protect against the battery overcharge damage caused by long time boost charge, a protect time setting is essential. The limit of time setting shall be configured by service engineer through the Vertiv software setting. 2.5.2 Advanced Function The UPS provides battery maintenance test function.
