  • Page 8: System Description

    3. System Description 3.1 Overview Parallel UPS configurations are recognised as either redundancy or capacity systems. The redundancy system is used to improve the system reliability with N+1 redundant UPS module. The capacity system for its part provides the maximum output power without focusing to the highest system reliability.

  • Page 9: Theory Of Operation

    3.2 Theory of operation A double conversion on-line UPS conditions the raw mains and supplies continuous, clean three-phase power to the critical systems. It keeps the battery constantly charged while feeding the critical load. The UPS will continue to supply clean power without any interruption at the output even at mains failure.

  • Page 10: Sizing

    The mains is rectified and boosted to DC power in the rectifier part. The rectifier provides power to the battery charger and the inverter load. The battery charger keeps the battery in recharged condition with ABM™ technology. The DC Link connects the rectifier output with the inverter input.

  • Page 20: Parallel Operation

    6.4 Parallel operation UPS modules have a cable connection between them to inform about the phase synchronism of the bypass voltages. It is needed in order to transfer the critical load back from the bypass line to inverters at the same time. The transfer from inverters to bypass functions without the data bus connection in case of overload situation.

    Local tie panel solutions The internal wiring diagrams of SPM9305 tie cabinets can be used as a reference when designing local tie panels. Parallel UPS configurations require a tie panel at the system output. It must facilitate service switches for each UPS module output. The system bypass switch is optional but helps when doing the maintenance for the whole parallel UPS system.

    8. Start-up and operation 8.1 Overview This chapter contains the necessary information on how to use the UPS system. The starting up and shutting down procedures described here are only used on a few occasions for example when preparing for a long term mains failure or changing the batteries. In normal operation the UPS system runs automatically.

  • Page 39: Operating System Bypass Switch

    Check that the optional system bypass switch is in the ‘BYPASS’ position, and the individual service switches are in the ON position. If the system configuration does not include the external system bypass switch, the critical load must be disconnected, (when cold battery start) or UPS modules must be started immediately after each one (during 30 seconds) to prevent overload situation at the system start-up.

  • Page 40: Shut-Down Procedure

    Check that the unsynchronised alarm is not active in the UPS modules. (Press Menu button, choose UPS status display) Turn the maintenance bypass switch to BYPASS position. Warning! The use of the maintenance bypass switch will cause a break in the output voltage if the input voltage or frequency is not correct and the UPS system is not synchronised to mains.

  • Page 41: Control Panel Operation

    It is possible to shut down a single UPS module and still get maximum protection for the critical load. This operation requires that the parallel system to be in the N+1 redundancy mode. In capacity mode, the system bypass switch should be used to transfer the system to bypass power.
