    1 Safety Precautions This manual contains information concerning the installation and operation of modular UPS. Please carefully read this manual prior to installation. The modular UPS cannot be put into operation until it is commissioned by engineers approved by the manufacturer (or its agent). Not doing so could result in personnel safety risk, equipment malfunction and invalidation of warranty.

    Read all the warning labels carefully before operation and  follow the instructions. WARNING When the system is running, do not touch the surface with  this label, to avoid any hurt of scald. ESD sensitive components inside the UPS, anti-ESD ...

  • Page 8: Battery Safety

    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.

    2.3 Power Module Description The power module structure is shown as Figure 2-2. The power module contains a rectifier, an inverter, and one DC charger. Output Input Rectifier Inverter AC/DC DC/DC DC/AC Battery DC/DC Figure 2-2 Power module schematic diagram 2.4 Operation Mode The modular UPS is an on-line, double-conversion UPS that permits operation in the following modes:...
  • Page 12 2.4.2 Battery Mode Upon failure of the AC mains input power, the inverters of power modules will obtain power from the batteries, and supply AC power to the critical AC load. There is no interruption to the critical load. After restoration of the AC mains input power, UPS will transfer automatically to normal mode.
  • Page 13 2.4.4 Maintenance Mode (Manual Bypass) When repairing the UPS system and battery or repairing the equipment failure, manually close the manual bypass switch, and the load is directly supplied by the mains power through the manual bypass to realize the emergency power supply to the load. Manual bypass mode schematic diagram is shown in Figure 2-6.
