  • Page 10: Product Overview

    2 PRODUCT OVERVIEW This section introduces the scope, product feature, work principle, modes, appearance, layout, alarm list and more of the UPS. 2.1 Product introduction HP i 33 40 kVA UPS is a high-frequency double conversion UPS. This high performance sine-wave UPS is specially designed for the network computer room, precision instruments, etc.
  • Page 11 Energy conservation and high efficiency Adopts advanced PFC control technology. The input power factor is greater than 0.99, which greatly improves the use ratio of electric energy and reduces the load of power grid, thus saving the cost of power distribution. The size of the UPS is small, and the weight is light, calorific value is small, which enhances the use ratio of environment and decreases the investment cost.

  • Page 12: Working Principle

    Working principle 2.2.1 Working principle diagram Maintenance bypass Bypass Input Bypass unit Bypass unit Mains Input Output Battery Input Power unit Power unit Figure 2-1. Working principle diagram 2.2.2 Working mode There are 4 working modes of the UPS: normal mains mode, battery mode, bypass mode and maintenance bypass mode.
  • Page 13 • When mains is normal, the rectifier, inside the power unit, rectifies the mains into anode and cathode DC voltage and stores energy in DC electrolysis for the inverter to use. The inverter absorbs energy from DC electrolysis and inverts to a stable output at 220 Vac voltage. When the system control card detects the inverter is normal, it will supply the inverting voltage to load.

  • Page 14: Appearance And Structure

    Maintenance bypass mode When the UPS needs to be maintained and the power supply for load cannot be interrupted, user can shut down the inverter and make the UPS work in bypass status. Switch on the maintenance bypassbreaker and switch off the mains pint breaker and bypass power supply breaker. while transforming the manual maintenance bypass, AC power is supplied for load by maintenance bypass breaker.

    6 USES AND OPERATIONS This section mainly introduces the operation procedures and methods, including using announcements, operation procedures, UPS start and parallel system start, etc. 6.1 Usage announcements • Before starting the UPS, check whether the load is proper. The load must not exceed the rated output power of the UPS, to avoid overload protection.

  • Page 74: Start Up

    Step 2 Check load. • Ensure that the load is not conductive load. The output of the UPS cannot be conductive load, such as motor, fan, air-condition, etc. Generally, these loads are power supplied by power-grid. • Ensure that the load is closed. At the same time, the load capacity should not exceed the UPS rated capacity, else it will cause overload protection.
  • Page 75 • Start the UPS by panel combination button. 1. Close the mains breaker (POWER). 2. 30 sec. later, long press the panel ON combination button for 3sec., the system inverters to output. Check the system running status in the touch screen, and ensure that the system turns to inverter from bypass to supply power.
