WARNING Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel.

  • Page 8: Introduction

    Introduction NTRODUCTION System Description The role of the parallel-redundant multi-module UPS system is to supply uninterruptible, clean power to the critical load. The UPS maintains a full-voltage, low-distortion output, even if the utility source power sags, becomes distorted or fails. If there is an outage of the source power, the UPS maintains power to the load until an alternate source of power is activated or until the original power source is restored.

  • Page 9: Figure 2 Multi-Module Ups, 500-750Kva

    Introduction In the unlikely event of a fault within the UPS, the SCC control logic, which continuously monitors all critical circuits within the UPS system, transfers the load to bypass without interruption and simul- taneously activates local and remote alarms. If a fault is detected in an individual UPS module, that module is automatically disconnected from the critical bus and shut down.

  • Page 10: Reliability

    Introduction Figure 3 System Control Cabinets Types of System Control Cabinets (SCCs) • SCCT—A stand-alone cabinet containing system control logic for up to six UPS modules, a static bypass switch, manually operated disconnects for the static bypass switch and two motor-oper- ated system circuit breakers.

  • Page 11: Safety Precautions

    Introduction Other Factors to Consider Reliability depends on more than just UPS module design. Improper installation can cause any sys- tem to fail. To prevent this, customer engineers from Liebert Global Services thoroughly inspect the installation of all our systems to ensure they are installed properly and operating within performance specifications.

  • Page 12: Recharge

    Introduction 1.4.3 Recharge After the utility source power is restored or an alternate power source becomes available, each recti- fier/charger slowly walks-in to once again power the inverters and recharge the battery plant. 1.4.4 Overload 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.

  • Page 15 Introduction 2. Battery Racks or Cabinets The battery racks are specifically designed for stationary service batteries. They are painted with electrolyte-resistant paint for corrosion resistance. Battery cabinets are available for 150 through 600kVA modules. 3. Module Battery Disconnect The UPS system utilizes a separate Module Battery Disconnect for remotely located batteries. A sensing circuit in the UPS module, set at the battery low voltage limit, trips the Module Battery Disconnect to safeguard the battery from excessive discharge.

  • Page 16: Theory Of Operation

    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 a System Control Cabinet (SCC), UPS modules and a back-up battery plant.

  • Page 19: 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 20: Battery Charging Circuit

    Theory of Operation 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 less than 0.5% RMS to preserve battery life during long-term float charging while the UPS system is operating on utility source power.

  • Page 21: 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.

  • Page 22: Static Bypass

    Theory of Operation 2.2.5 Static Bypass A static bypass is an integral part of the UPS System Control Cabinet (SCC). Refer to Figure 7. The static bypass consists of two reverse-paralleled SCRs (silicon-controlled rectifiers) per phase and solid-state switching devices working in conjunction with the motor-operated System Bypass Breaker (SBB).
  • Page 23 Theory of Operation Static Switch Isolation The motor-operated system bypass circuit breaker (SBB), wired in parallel with the static switch, automatically closes in approximately 200 milliseconds after the load is transferred to the bypass power source, removing the static switch from the power flow. Also, if required for maintenance, the static switch can be isolated from the bypass line by opening (to the OFF position) the Static Switch Disconnects.
  • Page 24 Theory of Operation Transfer and Retransfer Conditions 1. Automatic Transfers to Bypass Critical bus conditions that will initiate an automatic transfer of the critical load from the UPS system to the bypass source are: a. System Overload: overcurrent condition in excess of the overload rating of the System Control Cabinet (SCC).

  • Page 25: Redundant Mode

    Theory of Operation 6. Retransfer Inhibited A retransfer from the bypass source to the UPS system shall be inhibited if any of the following conditions exist: a. Manual (and Automatic) Retransfer Inhibitions: 1. UPS system-to-bypass voltage difference (ΔV) exceeds a predetermined percentage (normally 5%).
