    IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions for the 9900CX SERIES Uninterruptible Power Supply System that should be followed during installation and maintenance of the UPS and batteries. WARNING 1 Lethal voltages exist within the equipment during operation.
  • Page 8: Safety Precaution

    Since the UPS contain special industrial waste, such as capacitors, insulators or batteries, they cannot be disposed of like other general waste. Please check the disposal guideline of your district, contact the specialized contractor for disposal. MITSUBISHI ELECTRIC 9900CX SERIES UPS...
  • Page 9 If the UPS System is to be applied to support equipment that could affect human safety, the following steps must be adhered to: 1. Consult with Mitsubishi Electric Power Products Inc. UPS Division. 2. Special consideration of the overall back up power system configuration is required so that the Mitsubishi UPS System is not the sole support required for operation, maintenance and management of power availability.
