Introd uction 5 1.0 I NTRODUCTION The Liebert ® APM ™ UPS is a transformer-free, hardware-s calable, onli ne un interruptible power system with 208/12 0V input and 208/120V output capa bility. The Liebert APM can operate with either a 50 or 60Hz input and provide a matching output.
Introd uction 6 1.2 Battery Maintenance 1.2.1 Battery Safety Precautions Servicing of batteries should be performed or supe rvised by personnel know ledgeable of batte ries and the required precautions. Keep unauthorized person nel away from batteries.
Introd uction 7 NOTICE Risk of equipment damage. Batte ries should be clea ned with a dry cloth or a cloth li ghtly moistened with water. Do not use cleaners on the batteries.
Introd uction 8 Other DC Sources If the UPS system uses a DC source other than a factory-supplied Matching Battery Cabinet, perform maintenance on the DC source as recommended in the DC source manufacturer’s maintenance manual, available on the manufacturer’s Web site.
Installation 9 2.0 I NST ALLATION This section describes the Liebert ® APM ™ ’s environmental requirements and mechani cal considerations that m ust be take n into account when pla nning the positioning and cablin g of the UPS equipment.
Installation 10 2.1 Initial Inspections 1. While the Liebert ® APM ™ and ancillary ca binet s a re stil l on the truck, inspect the equipment and shipping contai ner for any signs of damage or mishan dling. Do not attempt to install the system if damage is apparent.
Installation 11 2.3.2 Environment al Considerations Before installing the Liebert ® APM ™ , verify that the UPS room satisf ies the environmental conditions stipulated in 11.2 - UPS Environmental , paying particular attentio n to the ambient temperature and air exchange system.
Installation 12 2.5 Mechanical Considerations The Liebert ® APM ™ is constructed with a steel frame and removable panels. Top and side panels are secured to the chassis by screws. The doors may be opened for access to power connections bars, auxiliary ter mina ls blocks and power switches.
Installation 13 2.5.4 Special Consid erations for Parallel Systems 1. Consider the groundi ng configuration of th e UPS system before finalizing module pl acement. For optimal ground performance, the Liebert ® APM ™ modules should be close together.
Installation 14 2.6.1 Optional Cabinet s If the Liebert APM installation in cludes a Liebert BDC, the UPS mu st be positioned to allow the Liebert BDC to be bolted to ri ght side of the Liebert APM (see Figure 1 ). The Liebert BDC must be cabled and bolted to the Liebert APM before the UPS and bypass cabinet are moved into their final position .
Installation 15 The Fault LED wi ll illuminate red when the Liebert FlexPower assembly has a problem. 2.9 St atic Bypass Assembly Figure 3 S t at ic byp ass assembly conn ections The Static bypass assembly has three Liebert Inte lliSlot interface card ba ys and connections for ancillary cabi nets (Liebert B DC and battery) an d for options.
Electrical Connectio ns—UPS 16 3.0 E LECTRICAL C ONNECTIONS —UPS The UPS requires both power and co ntrol cabling once it has been me chanically installe d. All control cables must run separate from power cables in metal conduits or metal ducts that are electrically bonded to the metalwork of the cabi nets to which they are connected.
Electrical Connectio ns—UPS 17 3.2.1 Rectifier and Byp ass Input Su pply of the UPS Overcurrent s Install suitabl e protective devices in the distribution unit of the incoming mains supply, considering the power cable current-carrying capacity and ov erload ca pacity of t he system.
Electrical Connectio ns—UPS 18 3.2.4 UPS Input Configuration By default, the Liebert ® APM ™ ships with internal l inks installed between th e bypass input and main (rectifier) input (single inp ut con fi gur ati on see Figure 48 ). Figure 4 shows the Liebert APM in a split bypass ( single source dual-input ) configuration.
Electrical Connectio ns—UPS 19 3.2.5 Cabling Guidelines The following are guidelines only and are superseded by local regulations and codes of pract ice where applicable.
Electrical Connectio ns—UPS 20 3.2.6 Cable Connection s The rectifier input, bypass output and battery are ea sily accessible from the right side of the unit for installation. All require lug type termina tions. They are connected to busbars on the right side of the Liebert ® APM ™ , as shown in Figures 5 and 6 .

Electrical Connectio ns—UPS 30 3.2.9 Protective Devices For safety, it is necessary to install circuit brea kers in the input AC supp ly external to the UPS system.
Electrical Connectio ns—UPS 31 Split By p ass Connections 6. If a split bypass config uration is used, connect the AC input su pply cables to the rectifier input terminals (A1-B1-C1-N1) and the AC bypass supply cables to the bypass input terminals (A2-B2-C2-N1 ) and tighten the connections to 24 0lb-in.

Electrical Connectio ns—UPS 33 3.4 Dry Cont act s The UPS provides input dry contac ts and output dr y contacts on the Auxi liary Terminal Block (ATB). 3.4.1 Input Dry Cont acts External input dry contacts are connected via the ATB. Dry contacts are availab le for en vironment detection, battery ground fault detection, etc.
Electrical Connectio ns—UPS 34 3.4.2 Output Dry Cont act s The Auxiliary Terminal Bl ock has three output dry contact relays (see Figure 18 and Table 6 ). Figure 18 Output dry cont act s and EPO wiring 3.4.3 Liebert BDC Interface The Liebert BDC interface is on the Auxi liary Terminal Block at J5.
Electrical Connectio ns—UPS 35 3.4.4 Battery Cabinet Interface Connect ors The battery cabinet interf ace is on the Au xi liary Termina l Block at J8 and J4 . Ref er to Figure 16 for the location of connectors J4 and J8 and to Figure 17 for circuit details.
Electrical Connectio ns—UPS 36 3.4.5 EPO Input—Optional NOTICE Risk of exceeding internal voltage limits. Can cause equipment damage. Do not apply more than 12 V t o the Emerg ency Power Off (EPO) i npu t. Exceed ing 12V on thi s input can damage the Liebert AP M’s internal circuitry and cont rol boards.
Battery Installation 37 4.0 B ATTERY I NST ALLATION 4.1 Introduction Emerson recommends that the batteries in external cabinets be the same typ e and ma de by the same manufacturer as the internal batteries in the Liebert ® APM ™ .
Battery Installation 38 4.3 UPS Batteries—Liebert ® APM 45kV A Frame Only The Liebert APM’s internal batteries are fully charge d before the unit is shipped. Duri ng storage and transportation, some charge is lost. All batteries sh ould be recharged before use.
