    A definite phase sequence is needed for the UPS to operate. If you encounter “IN SEQ FLR” alarm at start up, stop and switch off the UPS, ensure the protection devices (breakers/isolators) on the input distribution panels are “0”/”OFF” and then interchange any two phases on the UPS input only. Connect neutral to N terminal of X2.

  • Page 12: Modes Of Operation

    Modes of Operation There are three operation modes, which differ in the path of the energy flow. UPS block diagrams and the energy flow path in each operation mode is shown below: When UPS has no separate bypass mains input, bypass line is also fed from the mains input. Thus, if such a device is in question, mains input shall be comprehended when the bypass mains input is referred in the following sections of the manual.

  • Page 13: 3Rd1 Bypass Mode

    After start-up, the following applies: Operation mode depends on the priority, inverter, rectifier and bypass preferences made by the user and mains, separate by-pass mains and battery voltages. Priority and inverter, rectifier and bypass preferences can be set by using the COMMANDS and extra commands (EXTCMNDS) menus.

  • Page 14: 3Rd2 Normal Mode

    3.1Normal Mode Energy is drawn from the mains input. Loads are fed via the rectifier and the inverter. The AC voltage at the input is converted to a DC voltage by the rectifier. The inverter converts this DC voltage to an AC voltage with a stable sinusoidal waveform, amplitude and frequency.

  • Page 15: Control And Monitoring

    Control and Monitoring Front Panel The front panel located on the upper part of the UPS informs the user about operating status, alarm conditions and measurements. It also provides access to controls and configuration parameters. Front panel shown below consists of three parts. As mimic panel provides basic information about the energy flow path and existing alarms, LCD (liquid crystal display) offers detailed information and provides access to controls.

  • Page 22: 5Th3 Switching Into Manual By-Pass During Operation

    Switching into manual by-pass during operation Manual by-pass enables the user to isolate the electronic circuitry of the UPS from the mains and the load without interrupting the load operation by connecting the loads directly to the bypass supply. This feature is useful while performing maintenance or service and shall only be executed by authorized technical service personnel.

  • Page 23: Operating Procedures For Parallel Systems

    6 Operating Procedures for Parallel Systems Introduction EVO DSP UPS Systems are designed according to high MTBF figures with increased reliability but in case of necessity, a second ( or more ) EVO DSP UPS’s can be connected in parallel redundant configuration for supplying the very critical load to increase reliability.
  • Page 24 3) The Communication of parallel systems is made through CANBUS. Before starting up the UPS’s, make the connection of communication cables between UPS’s as per below diagram: ( COMMUNICATION CABLE CONNECTION BETWEEN PARALLEL UPS’s ) CAUTION: Do not remove the communication cables between the UPS’s during parallel operation.
  • Page 25 In case this communication cable is removed or damaged during parallel operation and the communication is lost then the slave UPS which can not communicate with the master UPS shall disconnect its output and maintain the OFF position. The other UPS’s shall continue their normal operation.

  • Page 27: Features And Operating Limits

    7 Features and operating limits Mains limits for normal operation Frequency and rms value of the mains input voltage has to be within acceptable limits for the UPS to operate in normal mode. Lower limit of the voltage depends on how much the UPS is loaded and it decreases as the load decreases until it reaches 80 V phase-neutral.

  • Page 28: 7Th4 Overload Behavior

    Overload behavior While operating in normal or battery mode, the UPS can feed overloads for a limited duration which is given in the “Technical Specifications” section. After that duration, UPS automatically switches into bypass mode, if the bypass is enabled and frequency/waveform/rms value of the bypass mains voltage is within limits.
