1.3.1

General

The Liebert APS UPS system shall consist of the appropriate number of modules for capacity and/or redundancy.

All modules shall operate simultaneously and share the load. In a non-redundant system, all the modules making up the UPS shall be required to supply the full, rated load. If a module should malfunction, the load shall be transferred automatically to the bypass line. If a battery module should malfunction, it shall be isolated from the system, resulting in reduced backup time. For redundant operation, the UPS shall have one or more modules more than what shall be required to supply the full, rated load. The malfunction of one of the modules shall cause that module to be isolated from the system and the remaining module(s) shall continue to carry the load. Replacement of a module shall be possible without disturbance to the connected load.

1.3.2

Modes of Operation

The UPS shall be designed to operate as a true on-line system in the following modes:

A. Normal—The critical AC load shall be continuously supplied by the UPS inverter. The power module rectifiers derive power from a utility AC source and supply regulated DC power to the inverter. The module’s inverter regenerates precise AC power to supply the connected equipment. The battery charger shall be in the power module and maintain a float-charge on the batteries of the UPS; additionally, the optional charger module shall also be used to maintain a quicker recharge time for long backup time applications.

B. Backup—Upon failure of utility AC power, the critical AC load shall be supplied by the inverter, which obtains power from the battery system. There shall be no interruption in power to the critical load upon failure or restoration of the utility AC source.

C. Recharge—Upon restoration of utility AC power, after a utility AC power outage, the input converter shall automatically restart and resume supplying power to the inverter. Also the battery charger shall begin to recharge the battery system.

D. Automatic Restart—Upon restoration of utility AC power, after a utility AC power outage and complete battery discharge, the UPS shall automatically restart and resume supplying power to the critical load. Also the battery charger shall automatically recharge the battery. This feature shall be enabled from the factory and shall be capable of being disabled by the user. The user shall also be able to program two auto restart delay settings.

 Battery capacity % level

 Countdown timer

E. Bypass—The bypass shall provide an alternate path for power to the critical load that shall be capable of operating in the following manner:

 Automatic—In the event of an internal failure or should the inverter overload capacity be exceeded, the

UPS shall perform an automatic transfer of the critical AC load from the inverter to the bypass source.

 Manual—Should the UPS need to be taken out of service for limited maintenance or repair, manual activation of the bypass shall cause an immediate transfer of the critical AC load from the inverter to the bypass source.
