    This manual contains information concerning the installation and operation of AEC IST6-US UPS. Please carefully read this manual prior to installation. The AEC IST6-US UPS cannot be put into operation until it is commissioned by engineers approved by the manufacturer. Not doing so could result in personnel safety risk, equipment malfunction and invalidation of warranty.
  • Page 6 Safety Precautions Move & Install � Keep the equipment away from heat source or air outlets. � In case of fire, use dry powder extinguisher only, any liquid Danger extinguisher can result in electric shock. � Do not start the system if any damage or abnormal parts founded.
  • Page 7 Safety Precautions voltage component is minimized. No risk exists to any personnel when operating the equipment in the normal manner, following the recommended operating procedures in this manual. � Riskof Fire.TO REDUCE THE RISK OF RIFE, REPLACE FUSESWITH THE SAME TYPE AND RATINGS.
  • Page 8 Safety Precautions � The battery contains sulfuric acid. In normal operation, all the sulfuric acid is attached to the separation board and plate in the battery. However, when the battery case is broken, the acid will leak from the battery. Therefore, be sure to wear a pair of protective glasses, rubber gloves and skirt when operating the battery.

    Overview 1.4.3 BypassMode If the inverter overload capacity 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. Should the inverter be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the load.
