Page 7: Important Safety Instructions
MPORTANT AFETY 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
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
System software allows the operator or Liebert Global Services to enter application specific informa- tion. Overload, overvoltage, battery discharge and shutdown limits can be set by the operator. In effect, UPS operations are tailored for each site. -

Page 19: 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
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
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 90: Manual Procedures
Manual Procedures The Liebert Series 610 UPS system is designed to function while unattended by an operator. The sys- tem control logic at the System Control Cabinet (SCC) monitors the performance of the UPS system, the availability of power sources and the current required by the critical load. - Page 91 Step 1. Before you apply power to the UPS modules, determine the position of the following circuit breakers and switches: a. Bypass Input Breaker (BIB) - If this circuit breaker is closed, you may already have power to the critical load through the bypass line. If this breaker is closed, leave it closed. If it is open, leave it open until you are ready to energize the bypass line.
- Page 92 Step 2. If the bypass line is not supplied to the SCC, the LCD screen will be blank. Energize the bypass line by operating the following controls: a. Close the Bypass Input Breaker (BIB). This breaker may be in your Maintenance Bypass cabinet.
