MODES OF OPERATION
The Nfinity UPS is designed to operate as a true on-line system in the following modes:
Normal ModeThe Power Module’s power factor correction circuitryderives power from the AC Mains and suppliesregulated DC power to the inverter. The module’sinverter regenerates precise AC power to supply theconnected equipment. The battery charger maintainsa float-charge on the battery.
Back-Up ModeWhen AC Mains fails, the connected equipment issupplied power by the inverter, which obtainsenergy from the battery modules. The connectedload will not be interrupted during the failure orrestoration of the AC Mains source.
Auto Restart ModeAfter a power outage and complete batterydischarge, once the AC Mains is restored, theUPS will automatically restart and resumesupplying power to the connected equipment. Thisfeature is enabled at the factory, but can bedisabled by the user. The user can also programtwo auto restart delay settings:
1. Battery capacity level (%)2. Countdown timer
Recharge ModeWhen AC Mains is restored, the unit will thenautomatically recharge the battery modules untilthey are fully charged.
Bypass ModeThe bypass provides an alternate path for power tothe connected equipment and operates in thefollowing manner:
• AutomaticIn the event of an internal fault or should theinverter overload capacity be exceeded, theUPS performs an automatic transfer of theconnected equipment from the inverter to thebypass source.
• ManualShould the UPS need to be taken out ofservice for limited maintenance or repair,manual activation of the bypass will cause animmediate transfer of the equipment from theinverter to the bypass source.

CABLE INSTALLATION
Wiring Preparation
Removing the Cover PlatesOn the back ofthe UPS, coverplates are overthe input andoutput terminals,as shown onright. Removethese using aPhillipsscrewdriver. Keepscrews and platesto one side.
Configuring the Bypass Voltage(TB2) (Transformer Models Only)The UPS voltage is factory set to 230V / 240V.Should the user have an AC Mains supply of 220V,the bypass voltage jumper will have to be changedto ensure correct output voltage during bypassmode.
Power Cable InstallationRefer to the chart below when selecting cables:
NOTES
If an output transformer is fitted and the start-up ison bypass the UPS has a six-cycle inrush currentthat is 20 times the rated output current. This mustbe taken into account when selecting the overloadprotection device at the AC input supplydistribution point. To avoid random tripping on startup, it is recommended that the AC input supply beprotected with a circuit breaker capable ofwithstanding this initial inrush. (An MCB rated tocurve “D” or specified as being “Type 4” (Britishstandard) is suitable for this purpose).
This UPS is fitted with EMI suppression filters.Earth leakage current is less than 40mA. Transientand steady state earth leakage currents may occurwhen starting the equipment. This should be takeninto account when selecting instantaneous RCCBor RCCD devices, as the earth leakage currents ofboth the UPS and load will be carried by these.
An overcurrent protection device (circuit breaker orfused disconnect switch) must be installed for theAC output.
This UPS does not incorporate automatic backfeed protection. A warning label must be fitted toall primary power isolators stating: ISOLATEUNINTERRUPTIBLE POWER SYSTEM (UPS)BEFORE WORKING ON THIS CIRCUIT. Earth inaccordance with local electrical codes.
WARNINGPlease read this section thoroughly beforeattempting to install wiring to this unit.
Be sure that the unit is not connected to any ACMains power source before installing any wiringto this unit. This UPS should be installed by aqualified / certified electrician.

MODULE REPLACEMENT
Follow the instructions below when replacing acontrol, battery, or power module, or when addingmodules to the system. To order additionalmodules, contact your Liebert representative.
Removing Modules1. Remove bezel cover of appropriate module.
When replacing a Power or Battery Module,verify the faulty module by confirming theamber LED is lit.
2. If removing a Control or Power Module with noredundant modules, switch UPS to manualbypass. Switch SW2 off (0) to minimize risk ofdamage to modules.
3. Pull out and lift the lever if replacing a Controlor Power Module, then turn fastenercounterclockwise until it is loosened.
4. Start to pull out module. About 2/3 out it willstop. Slide module away from the centre of theUPS.
CAUTION: Battery Modules are heavy—30 kg (66 lb). Make sure to use two people whenremoving a Battery Module. Continue to pull untilmodule is removed (seen at right).
5. Dispose of module in an environmentallyresponsible way that complies with localcodes / regulations or return to Liebert forproper disposal.
Note: Battery Modules may contain shippingscrews. These screws may be removed anddiscarded.
WARNINGPOTENTIAL TIP HAZARDInstall all modules starting from bottomto top bays. For module removal startfrom top to bottom bays. Do notremove more than one module at atime. Failure to do so may cause unit totip over and cause serious injury.

Replacing Modules
1. Lift module to appropriate bay, resting end ofmodule on bay shelf. Use caution not to restthe module on the lower bezel cover.
2. Push module into bay. Once halfway in, slidemodule sideways toward the centre of theUPS. Continue pushing module until fullyinserted.
3. Press and turn fastener clockwise until locked.If replacing a Control or Power Module, presslever down.
4. Wait about 30 seconds as the moduleperforms a start-up test and synchronizes withthe other modules. Both the amber and greenLEDs should be flashing. A green flashingLED will then confirm the module is properlyconnected.
5. If UPS was placed in bypass manually,transfer back to UPS operation.
6. Replace bezels.
Replacing the UserInterface
1. Lift off user interface and set it on top of theUPS frame.
2. The attached cable will be connected to anIntellislot card, found in a port between thecontrol modules.
3. Disconnect the cable from the Intellislot card.4. Install the new Intellislot card in the UPS.5. Plug the new user interface cable into the
Intellislot card.6. Set replacement User Interface into proper
position.
Note: Power Modules must be installed in a bayin the top half of the Nfinity frame. BatteryModules can be installed in any bay of the UPSframe.
Note: When replacing the Control Module,record user configuration data before removing.Re-verify the configuration settings after thenew Control Module is installed.
