  • Page 11: Operation Modes

    KEOR T 4. Operation Modes Uninterruptible Power Supplies (UPS) most important function is the protection of critical and sensitive loads from the irregular mains voltage conditions. They are used to supply uninterruptible energy to these loads in such irregular mains voltage conditions and provide regulated energy supply to the equipment present in the IT room, industrial workshop, hospitals and offices.

  • Page 12: Battery Mode

    4.2. Battery Mode In this operation, energy is drawn from the batteries. The loads are supplied via inverter. Output voltage is sinusoidal and has a regulated amplitude and frequency. Battery voltage should be in acceptable limits and the inverter should be enabled for the UPS to operate in this mode.

  • Page 13: Bypass Mode

    Bypass Mode Operation voltage tolerance limit can be adjusted in certain ranges depends on the customer’s request on site by Legrand UPS Technical Service Personnel. To return to Bypass Mode Operation; the mains voltage should turn back to +5V above of lower limit,...

  • Page 14: Eco Mode

    4.4. Eco Mode Eco Mode Operation can be chosen through the Commands Menu. The purpose of using this mode is to increase the efficiency up to 98% and to provide energy saving; since the loads are supplied by the mains voltage directly, the loads are unprotected against any possible future risks.
