    NSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and mainte- nance of your Series 610 UPS and batteries. WARNING Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel.

  • Page 8: Introduction

    If the critical load current exceeds the rated load of the Series 610 UPS system, the control logic deter- mines the magnitude of the overload and reacts appropriately. Overloads are usually the result of inrush current requirements.

  • Page 9: Reliability

    Series 610 UPS provides easy-to-follow, prompted instructions on the industry’s largest operator dis- play screen. If you ever need help, call Liebert Global Services (24 hours a day at 1-800-LIEBERT) or your Liebert distributor or sales representative. Your attention to proper installation, operation and periodic main- tenance will ensure that your mission-critical operations receive the best possible protection from electrical disturbances and outages.

  • Page 10: Safety Precautions

    Introduction Safety Precautions Read this manual thoroughly, paying special attention to the sections that apply to you, before work- ing with the UPS. Also refer to the battery manufacturer’s manual, available on the manufacturer’s Web site, before working on or near the battery. Under typical operation and with all UPS doors closed, only normal safety precautions are necessary.

  • Page 11: Modes Of Operation

    Overloads in critical systems may be caused by inrush currents during connected equipment start-up or by faults in the critical load or distribution network. The Liebert Series 610 UPS system can main- tain full output voltage regulation while sustaining the following overloads: •...

  • Page 12: Operator Controls

    Operator Controls Liebert Series 610 UPS modules are equipped with a microprocessor-based Operator Display Screen and Control Panel designed for convenient and reliable operation. The front panel location of the mon- itoring and control system enables the user to quickly identify the current status of the UPS and to perform most of the manual operations.

  • Page 13: Options

    1. Battery and Racks The batteries provide power in the event of a power outage. The Liebert UPS can use a variety of battery types, provided the battery plant is designed for the UPS DC voltage range and the load requirements of your application.

Customer Alarm Interface This optional interface board allows the input and display of 8 alarms from customer-supplied contacts, each with a customer-selected name of up to 16 characters. The following attributes can be user programmed for each alarm: latching, summary, freeze history, sound horn, auto-dial and time delay (0 to 999.9 seconds).

  • Page 15: Theory Of Operation

    HEORY OF PERATION General Component Descriptions The UPS system includes all of the equipment necessary to continuously provide computer-grade AC power to a critical load, even when there is an interruption of the utility power. It consists of the UPS modules and a back-up battery plant.

  • Page 17: Rectifier/Charger

    Theory of Operation 2.2.2 Rectifier/Charger The UPS module rectifier/charger consists of an input circuit breaker, AC current limiting circuit, battery equalize charge circuit, DC filter, battery charge current limiting circuit and bridge rectifiers. Optional items are an isolation transformer and a 12-pulse rectifier (these are standard on 1000kVA units).

  • Page 18: Battery Charging Circuit

    2.2.3 Battery Charging Circuit The UPS module charging circuit is capable of recharging the battery plant to 95% of full capacity within 10 times the discharge time. Recharging the last 5% takes longer because of characteristics inherent in the battery. DC ripple voltage is limited to 0.5% RMS to preserve battery life during long- term float charging while the UPS system is operating on utility source power.

  • Page 19: Inverter

    Theory of Operation 2.2.4 Inverter The inverter is a solid state device that converts the DC output of the rectifier/charger or the battery to AC power. Operation The inverter converts DC power—from either the battery or the rectifier/charger—into three pulse- width-modulated/six-step waveforms.

    1000% rated full load current (as limited by distribution feeders) from the bypass source to clear the overload without closing the bypass circuit breaker (a Liebert design exclusive). The bypass source is in parallel with the UPS system, permitting the bypass source to carry the initial overload current.

    Manual Procedures The Liebert Series 610 UPS is designed to function while unattended by an operator. Many important functions are handled automatically by the system control logic, as explained in 3.5 - Automatic Operations. Other procedures must be performed manually.
  • Page 76 STEP 1 (Start-Up Procedure) Before you apply power to the UPS modules, determine the position of the following circuit breakers and switches: a. Rectifier Input Breaker (RIB) - If this external circuit breaker is closed, you already have power to the UPS cabinet and possibly power to the controls. If this breaker is closed, leave it closed.
  • Page 77 STEP 3 (Start-Up Procedure) During a start-up procedure, power is supplied to the critical load through the internal bypass line while the UPS module is being energized. Depending on the reason for your UPS module shutdown, you may already have power through the bypass line. You can determine this by observing the Moni- tor/Mimic Display screen now that Control Power is available.
