  • Page 13: Cooling Of The Premises

    Cooling of the premises The recommended operating temperature for the lifetime of the UPS and of the batteries is from 20 to 25°C. The lifespan of the battery depends on the operating temperature; with a rise temperature of 10°C above 20°C , the lifespan of the batteries is halved. A heat dissipation system is required to keep the temperature of the premises where the units are placed within the range of 20-25°C.

    SWMB (only in MASTER HP – UL TCE version) The mechanical bypass switch SWMB must not be closed during normal operation of the UPS. SWMB should only be closed during UPS maintenance operations in order to keep the load powered (see the instructions on page 38). When the UPS is first started up, it is in on-line mode (see page 37 ).

  • Page 37: 1.1.15 On - Line - Factory Setting

    1.1.15 On - line - factory setting - Load is always powered by the inverter, in the event of an input mains outage the load continues to be powered from the inverter using the energy stored in the batteries. On – line: The load is always powered by the inverter, with steady voltage and frequency, using the energy from the mains power supply (INPUT).

    1.1.18 Stabilizer (operation in on-line mode without battery) Load is supplied by inverter, if there is a mains failure the load is not powered, the batteries are not present. Stabilizer: This mode of operation makes the UPS a power conditioner with no backup capability. The load is always powered through the inverter, with steady voltage and frequency, using the energy from the input mains.

  • Page 39: Ups And Load Shutdown

    Static bypass is an automatic electronically switched bypass path. It is engaged if the inverter is overloaded or if fails. Also, the static bypass is the normal source of the load if the UPS is in “Standby On” Mode or if it is in “Smart Active” Mode, with the inverter taking the load if the bypass source is out of range.
