  • Page 7: How To Use This Manual

    HOW TO USE THIS MANUAL A proper understanding and use of this operating and maintenance manual will enhance UPS system reliability. Therefore, the manual should be given equal status with the tools and equipment used to align and maintain the system. Conversely, improper understanding or application of the principles set forth can result in impaired system operation, loss of power to critical equipment loads, injury to personnel and/or damage to the UPS.
  • Page 8 Damage Documentation It is the responsibility of the recipient to file claim with the carrier for damages to the equipment or notify IPM, depending on the f.o.b. point. Any and all damage noted upon receipt of the UPS, battery pack and/or PDU should be clearly identified in detail on the Bill of Lading.

  • Page 10 Purchaser shall not operate the system outside the specifications as stated in the system manual, and shall follow all operating instructions therein. Any necessary repairs made during the period of this warranty shall be made by IPM or by others with IPM’s written concurrence.

  • Page 11: Rectifier/Charger

    SECTION I Theory of Operation 1.1 General The BalancedPower Plus® (BP+) Uninterruptible Power System (UPS) presented in this manual is a solid state, on-line system designed to provide high quality, continuously filtered and conditioned ac power to computers, their peripherals and/or other critical equipment loads. Most commonly, the UPS is configured as a single, stand-alone unit.

  • Page 12: Inverter

    SECTION I Theory of Operation Inverter The inverter changes dc voltage to precision ac voltage through pulse width modulation (PWM) inversion. Output isolation transformers and an output filter provide “clean”, computer grade ac which is then sent to the critical load. When utility power is available, the rectifier supplies power to the inverter.

  • Page 13: Control Logic And Control Circuitry

    SECTION I Theory of Operation 1.5 Batteries (continued) The rectifier/charger normally provides a maintaining or “float” charge to the batteries. Following periods of discharge when the batteries have supplied power to the inverter, the rectifier/charger increases power to the batteries in order to recharge them.

  • Page 14: Multi-Level Passwords

    SECTION I Theory of Operation 1.8 Multi-Level Passwords A password is required to access and make use of the UPS Maintenance Menu, described in Section 3.6.3. This menu, with five subsections, makes possible the performance of a variety of maintenance functions including transfer and retransfer to bypass, password changes and adjustment of time and date.

  • Page 15: Phone Home Alarm Reporting

    1.9 Phone Home Alarm Reporting When this UPS is activated for phone home operation and the UPS senses one of several pre-selected alarm conditions, the UPS automatically dials IPM’s Field Service computer without human assistance and notifies IPM’s Field Service personnel of a system problem requiring attention.

  • Page 16: Theory Of Operation

    SECTION I Theory of Operation 1.10 Dial-Back Security (continued) controls. In this way high level security is provided since the remote operator must know the dial-back and access passwords and be calling from the proper associated phone number. An internal modem and a dedicated telephone line are required. Dial-Back Security can be activated only with a Field Service level of password.
