Safety Precautions This manual contains information concerning the installation and operation of this Liebert APM modular UPS This manual must be read prior to installation. The UPS must be commissioned and serviced by engineers approved by the manufacturer (or its agent). Failure to do so could result in personnel safety risk, equipment malfunction and invalidation of warranty. The UPS has been designed for commercial or industrial use only, and is not for use in any life support application.
Battery voltage exceeds 400Vdc All physical battery maintenance and servicing requires the use of a tool or a key and should be carried out only by trained personnel. Special care should be taken when working with the batteries. When connected together, the battery terminal voltage will exceed 400Vdc and is potentially lethal. Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the vicinity of, a large bank of battery cells.

Chapter 1 Installation 1 Chapter 1 Installation This chapter introduces the installation of Liebert APM modular UPS, including preliminary checks, location, positioning, cable connection and installation drawings. 1.1 Introduction This chapter describes the requirements that must be taken into account when planning the positioning and cabling of the UPS. This chapter is a guide to general procedures and practices that should be observed by the installing engineer.
2 Chapter 1 Installation If necessary, install a system of room extractor fans to avoid room temperature build-up. Optional air filters are available if the UPS is to operate in a dusty environment. Note: The UPS is suitable for mounting on concrete or other non-combustible surface only. 1.3.2 Battery Room The batteries will generate small amount of hydrogen and oxygen at the end of battery charge.
Chapter 1 Installation 3 1.4.1 UPS Composition The UPS structure is shown in Figure 1-1. The UPS configuration is provided in Table 1-1.
4 Chapter 1 Installation 1.4.3 Clearances The UPS has no ventilation grilles at either side; therefore, no clearance is required at either side. To enable routine tightening of power terminations within the UPS, in addition to meeting any local regulations, it is recommended to provide adequate clearance in the front and at the back of the cabinet for unimpeded passage of personnel with the doors fully opened for accessing cable termination. Refer to Figure 1-15 for the positioning of the cabinet.

Chapter 1 Installation 7 1. Protective earth cable: Follow the most direct route possible to connect the earth cable to the cabinet. The earth cable shall be sized in accordance with the AC supply fault rating, cable lengths and type of protection. Typical 2 cross sectional area (CSA) is 80mm (150kVA) according to AS / IEC60950-1. 2. When sizing battery cables, a maximum volt drop of 4Vdc is permissible at the current ratings given in Table 1-3.
8 Chapter 1 Installation at the rear of the UPS cabinet. Tighten the output neutral bar connections to 5Nm (M6 bolt). Ensure correct phase rotation. z In case output distribution modules are not installed, please connect the output cables between the output terminals in the front of the UPS cabinet and the loads, and connect the output earth cable to the output earth terminal at the rear of the UPS cabinet.

16 Chapter 2 Operation Chapter 2 Operation This chapter introduces the basic knowledge of UPS operation, including the operating theory, operation mode, battery management and battery protection of the UPS. Warning: hazardous mains and battery voltage present behind covers 1. No user-serviceable parts are located behind covers that require a tool for their removal. 2. Only qualified service personnel are authorised to remove such covers. 2.
Chapter 2 Operation 17 During normal operating conditions, the inverter output and bypass supply must be fully synchronized so as to achieve a clean (no-break) load transfer between the inverter output and static bypass line. The synchronization between the inverter output and static bypass is achieved through the inverter control electronics, which make the inverter frequency track that of the static bypass supply, provided that the bypass remains within an acceptable frequency window.
18 Chapter 2 Operation interruption is programmable but typically set to be less than 3/4 of an electrical cycle, for example, less than 15ms (50Hz) or less than 12.5ms (60Hz). 2.2.5 Maintenance Bypass Mode If UPS maintenance or repaired is needed, you may use the manual maintenance bypass switch to transfer to the load to the maintenance bypass, with no interruption in power to the load.
Chapter 2 Operation 19 2.3.2 Advanced Function——Battery Self-Test And Self-Service At periodic intervals 20% of the rated capacity of the battery will be discharged automatically. The minimum amount of load must exceed 20% of the nominal rating of the UPS. If the load is less than 20%, auto-discharge cannot be executed. The periodic interval can be set from 30 days to 360 days. The periodic testing can also be inhibited.
20 Chapter 3 Operating Procedures Chapter 3 Operating Procedures This chapter provides detailed operating procedures of the UPS. All control keys and LED indication mentioned in these procedures are identified in Chapter 4 Operator Control And Display Panel. Audible alarm may sound at various points during these procedures. It can be canceled at any time by pressing the SILENCE ON/OFF key. Warning: hazardous mains and battery voltage present behind covers 1.
Chapter 3 Operating Procedures 21 3.2.1 Start-Up Procedures (Into Normal Mode) Procedures are as follows for starting the UPS from a fully powered-down condition: Warning During these procedures the output terminals are live.
