Product Introduction Operating Modes The Liebert APS UPS is a true online double-conversion system, having the following operating modes: • Normal Mode • Backup Mode • Auto Restart Mode • Bypass Mode Normal Mode The power module rectifiers derive power from a utility AC source and supply regulated DC power to the inverter.
Extending more than one module at a time could cause the unit to tip over. All UPS components are located in the Liebert APS frame. The front of the UPS consists of a series of plastic bezels. By grasping these bezels from the sides and pulling straight out, you can remove the bezel to reveal the battery/power module bays.
Except for the silkscreen, the appearance of the system control module and the system monitor module is as shown in Figure 8. Figure 8 Liebert APS system control module and the system monitor module Handle Securing Hole...
Product Introduction 1.5.4 Power Module The power module is shown in Figure 9. Figure 9 Liebert APS power module Green Status LED Yellow Fault LED Locking Lever FRONT VIEW Fastener Each power module is an independent 5kVA unit, consisting of a power factor corrected rectifier, battery charger and inverter, with associated monitoring and control circuitry.
The battery module strings work in parallel to provide longer backup time for the UPS. A Liebert APS can be configured with, at most, four external battery cabinets. An external battery cabinet is shown in Figure 12.
2.1.3 Installation Site Consider the weight and size of the Liebert APS when deciding where to install the unit. Verify that the floor can support the weight of a fully loaded unit, any accessories and external cabinets. Verify that the UPS will be in a well-ventilated area with at least 12 inches (305mm) clearance behind it.
Installation Unloading the UPS The unit frame is bolted to the shipping pallet to ensure safety during shipping. Emerson recommends keeping the unit bolted to the pallet and using a pallet jack to transport the unit to its installation location.
Installation Mechanical Installation Two installation modes are available for the Liebert APS UPS: tower installation and rack installation. 2.3.1 Tower Installation 1. Once the UPS is in the desired location, adjust the leveling feet to secure its position, as shown in Figure 16.
2U space of all four rack posts. These cage nuts will secure the optional shelf that will support the weight of the Liebert APS. b. Install a cage nut in the middle square hole of 4U, 6U, 10U, 12U spaces, respectively, again in all four posts.

2.5.1 Transformer-Free UPS Cable Connection A junction box is factory-installed on each model of the Liebert APS to ease cable connection. Select the appropriate input cables according to Table 3 and Table 4 based on the UPS rating and mains frequency; however, it is recommended that you size the over current protection and wiring for the frame rating to easily allow upgrades to the UPS system.
Installation To connect the cable: NOTE Input and output cables must be run in separate conduit before cable connection. For the user whose input power grid is L-L line voltage, the input N of the power input and output terminals will connect live wire, so the output N of the power input and output terminals is also live wire.
The UPS grounding should be in accordance with local regulations. A junction box is factory-installed on all models of the Liebert APS to ease cable connection. Select the appropriate input cables according to Table 5 and Table 6 based upon the UPS rating and mains frequency.
Installation Configuring the Bypass Voltage The UPS bypass voltage is factory-set to 208V (the jumper copper bar has been installed). Should the user have a utility supply of 200V/220V/230V/240V, the bypass voltage jumper must be changed to ensure correct output voltages when in bypass mode. Configuring the bypass voltage jumper settings are shown in Figures 34 and 35.
Installation Configuring the Neutral/Earth Jumper The UPS contains an isolation transformer that generates a neutral conductor for the connected load. The UPS is a separately derived source and contains a neutral/earth jumper. A factory-installed neutral/earth jumper copper bar may require removal to comply with local codes and regulations. Figure 36 Configuring the neutral/earth jumper Neutral/Earth Jumper Connecting Cables...

2.5.3 Transformer-Free UPS—Dual Inverter Frames A junction box is factory-installed on all models of the Liebert APS to ease cable connection. Select the appropriate input cables according to Tables 9 and 10 based on the UPS rating and mains frequency. Emerson recommends sizing the overcurrent protection and wiring for the frame rating for easing upgrades to the UPS system.
Installation 4. Respectively secure the input/output cables through the cable bridges on the rear panel of the UPS (see Figure 40). Figure 40 Secure cables on cable bridges The connections for the single-phase input mode and the 3-phase input mode are shown in Figure 32 and Figure 33, respectively.
Installation 2.5.4 Connecting External Battery Cabinet Up to four external battery cabinets may be connected to the Liebert APS to provide longer battery run times. An external battery cabinet contains a standard battery cable and a communication cable, each 1meter (39in) long. They are used to connect UPS and the external battery cabinet. Optional cables of 3 and 5 meters can be provided if the battery cabinets must be located some distance from the UPS cabinet.
Figure 43 Connecting external battery cabinet (transformer-based UPS) Communication Cable Battery Cable Liebert APS Battery Cabinet After connecting the external battery cabinet, use the user interface to determine the number of external battery cabinets, as shown in Figure 44. Figure 44 Battery screen...
UPS output voltage is set to 220/127V. 5. Secure the POD by using the two screws removed in Step 2. 6. Repeat Steps 1 through 5 to install a second POD on the Liebert APS (only the 16-bay frame has two POD ports).
Page 45
If using the integral distribution PODs on the UPS or MBC, verify that the individual POD breakers are closed. 6. Emerson recommends closing the UPS input breaker; it is on the front of transformer-free frame systems and on the rear of transformer-based frame systems. If AC mains becomes available, the UPS will revert to AC power mode and begin recharging the battery.
Liebert IntelliSlot Ports (with protective covers) Liebert IntelliSlot Unity Cards—IS-UNITY-LIFE, IS-UNITY-S, IS-UNITY-DP • IS-UNITY-LIFE: This card is standard in every Liebert APS. It is used for communication between the Liebert APS UPS and Emerson’s Trellis ® NMS and LIFE Services.
Provides dry contact alarm information, including: On Battery, Low Battery signals for communication to four servers for use with Liebert MultiLink software. Liebert IntelliSlot EBC Card This card is used for the Liebert APS UPS to monitor and manage the intelligent battery modules in external matching battery cabinets. Dry Contact Ports The UPS provides dry contact ports.
REPO (Remote Emergency Power Off) The Liebert APS is equipped with a REPO (Remote Emergency Power Off) connection. Only the SELV (Safety Extra Low Voltage) circuit can be connected to the REPO terminal block. Figure 48 shows the REPO connection pin layout.
