    ⟡ This UPS full complies with “IEC62040-1-1-General and safety requirements for use in operator access area UPS”. Dangerous voltages are present within the battery box. However, the risk of contact with these high voltages is minimized for non-service personnel. Since the component with dangerous voltage can only be touched by opening the protective cover with a tool, the possibility of touching high voltage component is minimized.

  • Page 11 Figure 1-5 Battery Mode operation diagram Note: With the function of “Battery Cold Start”, the UPS could start without utility. See more detail in section5.1.2. 1.2.2.3 Bypass Mode If the overload capacity of the inverter is exceeded under Normal mode, or if the inverter becomes unavailable for any reason, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no interruption in power to the critical AC load.
  • Page 12 1.2.2.4 Maintenance Mode (Manual Bypass) A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS becomes unavailable e.g. during a maintenance procedure. The Maintenance mode structure is shown in Fig.1-7. Figure 1-7 Maintenance mode operation diagram Danger During Maintenance mode, dangerous voltages are present on the terminal of input, output and neutral, even with all the modules and the LCD turned off.
  • Page 13 Note There is a short interruption time (less than 10ms) when transferring from ECO mode to battery mode, it must be sure that the interruption has no effect on loads. 1.2.2.6 Auto-restart Mode The battery may become exhausted following an extended AC mains failure. The inverter shuts down when the battery reaches the End of Discharge Voltage (EOD).
