Description of the Symbols Used on the Labels Applied to the UPS PE: PROTECTIVE EARTH PB: PROTECTIVE BONDING DANGER! HIGH VOLTAGE (BLACK/YELLOW)

  • Page 9: Important Notice For Ups

    • UPS requires 3Ph-N+PE input connection. • Do not connect the output neutral to the protective ground or protective bonding. KEOR T EVO does not modify the neutral arrangements of the system; the use of an isolation transformer is required should it be necessary to modify the neutral arrangements downstream KEOR T EVO.

  • Page 10: Important Notice For Battery

    Important Notice for Battery • The batteries may only be installed and commissioned by authorized LEGRAND UPS Technical Service Personnel. • Make sure that the battery qty is proper for the unit and they are same type and capacity. Otherwise danger of explosion and fire is within the bounds of possibility.

  • Page 11: Operation Modes

    IT room, industrial workshop, hospitals and offices. KEOR T EVO UPS during Online mode operation provides stable pure sine wave not affected by input voltage fluctuations. This helps to extend the life time of your sensible loads. Power factor of the current consumed from mains is nearly one.

  • Page 12: Battery Mode

    • If Inverter enabled: “YES”, Rectifier enabled: “NO” are selected through the front panel (Authorisations Menu for authorized Service Staff ). KEOR T EVO UPS operates with one or several parallel strings of 1 x 60pcs 12VDC battery with common neutral.
