  • Page 3: Introduction

    1. Introduction This manual is designed to ensure the safe and correct operation of the TOSNIC-7000S Uninterruptible Power System (hereafter referred to as "UPS unit"). Please read the "Safety Precautions" and "Operation" sections of this manual carefully before use and make sure you have a thorough understanding of the information in these two sections.
  • Page 4 Special considerations (*) are required when using equipment that affects the lives and safety of human beings (**) or has a critical effect on maintaining public services (***). Be sure to contact Toshiba in such cases. The use of such equipment without special consideration may result in serious accidents.
  • Page 5 52R and 72B. Continued use may result in fire. Contact the Toshiba Service Center. Contact the Toshiba Service Center in the event of malfunction or failure. This unit should be repaired only by authorized Toshiba service personnel. Servicing by untrained personnel may increase the scale of the failure or result in electric shock or injury.
  • Page 6 Safety Precautions (continued) Do not open the rear door. The parts inside carry high voltage. Touching them may result in electric shock, burns or failure. Operators should be qualified* personnel. Operation of the UPS by unqualified or untrained personnel may result in electric shock, injury or failure. In accordance with customer stipulations Make sure the air vents on the front and top of the unit are not blocked.
  • Page 7 Safety Precautions (continued) Checking warning labels (1) The locations of the warning labels on the UPS are shown in Figure 2.1. Check to make sure that these warning labels are in place. Note that the placement and content of the warning labels may differ depending on the capacity of the UPS.

  • Page 8: Handling Precautions

    Be sure to have periodic maintenance work and inspections done by Toshiba service and maintenance personnel. For more information on servicing programs and fee options, contact the Toshiba Service Center.
  • Page 9 Handling Precautions (continued) Do not turn the circuit breakers ON when control power source switch (8A) is OFF. This may result in failure. Certain units also have a control power source switch (8D). This switch has the same functions as the switch 8A. Do not turn the control power source switch (8A) to the OFF position when the circuit breakers are ON.
  • Page 10 Handling Precautions (continued) When the unit has stopped due to failure, be sure to remove the memory card before resetting the LCD Failure Error screen on the panel. Resetting (restarting) the UPS without removing the memory card will delete the data needed to determine the cause of the failure. Do not leave the unit for long periods of time (1 week) with control power source switch (8A) in the OFF position.
