How to use this Manual This manual is designed for ease of use, giving the user easy and quick reference to information. This manual uses notice icons to draw attention to the user important information regarding the safe operation and installation of the UPS. The notice icons used in this manual are explained below, and should be taken into account and adhered to whenever they appear in the text of this manual.
1 INTRODUCTION The Toshiba Uninterruptible Power Supply System (UPS) is designed to provide many years of reliable protection from power failure, brown-outs, line noise, and voltage transients. To ensure optimum performance of the equipment, follow the manufacturer's instructions. This manual contains descriptions required to operate the UPS. Please read this manual carefully and retain it for future reference. IMPORTANT SAFETY INSTRUCTIONS 1.1.1.1.1.1.1.
WARNING 2 CAUTION In no event will TOSHIBA be responsible or liable for either indirect or consequential damage or injury that may come from the use of this equipment. Don’t modify the UPS entirely or partially. Any modifications without authorization by TOSHIBA could result in personal injuries, death or destruction of the UPS. PROHIBIT 1.1 SAFETY PRECAUTIONS APPLICATION This UPS shall NOT be applied to support equipment (*) that could affect human lives.
! WARNING 3 NOTE 4 The UPS is to be installed in a controlled environment. Improper storage and installation environment may deteriorate insulation, shorten component life and cause malfunctions. Keep the installation environment per standard described as follows: TABLE 1.1 No.
! WARNING 4 NOTE This UPS does not include a Bypass input circuit breaker (MCCB) to protect the bypass circuit. The Bypass input circuit breaker (MCCB) is to be field supplied and installed. Recommended Breaker (MCCB)'s Specifications are as follows: TABLE 1.
1.2 GENERAL The Toshiba G9000 UPS is designed to provide continuous and clean electrical power to a critical load. Additionally the UPS monitors power conditions affecting the load. In the event of an input power failure, the UPS will supply power to the critical load for the specified battery time. If the input power is not restored promptly, back up power from the UPS battery permits the orderly shutdown of equipment supported by the UPS. The UPS is simple to start-up, operate and maintain.
1.3 DEFINITIONS UNINTERRUPTIBLE POWER SUPPLY SYSTEM (UPS) - All components within the UPS Module Cabinet and associated batteries that function as a system to provide continuous, conditioned AC power to a load. This is sometimes referred to as the "System". UPS MODULE CABINET - The metal enclosure which contains the Converter / Charger, Inverter, Static Transfer Switch, Internal Bypass line, operator controls, and internal control systems required to provide specified AC power to a load.
1.4 OPERATION OVERVIEW The UPS provides two power paths between the utility source and the critical load. Figure 1.1 shows the path for normal operation, with the load powered by the inverter. Figure 1.2 shows the path for bypass operation, with the load supplied through the static bypass line. A) Normal operation: Load power supplied by each system UPS inverter. FIGURE 1.
In the event of a UPS module failure during Parallel Operation, the critical load power will be continually supplied and shared by all other UPS. ! The Bypass Input breaker and cables are to be supplied and installed by the user or the constructor. (See WARNING 4 on page 1-4) NOTE B) Bypass Operation: Load Power supplied through UPS internal static bypass line. FIGURE 1.2 Single Line Diagram - Bypass Operation: Load fed through static bypass line.
In the event of a load overcurrent, the UPS transfers to bypass without interruption to the critical load. In the case of the Parallel Operation, all UPS will transfer to bypass without interruption to the critical load. The internal control system determines the operation of the two paths, with the load powered from the inverter being the normal operation. C) Battery operation: Load Power supplied by UPS battery. FIGURE 1.
When power is restored after a low battery shutdown, the UPS converter(s) automatically restarts operation, the charger(s) recharges the batteries and the Inverter(s) is automatically restarted without operator intervention. Load is automatically assumed by the inverter without operator intervention.
