Page 5: Introduction
1. Introduction This User’ s manual gives basic information about IGBT and SCR (rectifier) 80 - 130 kVA, uninterruptible power supplies: their basic function, their features, how to use them, and what to do in case of trouble. Instructions for shipping, storing, handling and installing the equipment are also given. - Page 6 UPS block diagram An UPS module consists of several blocks each having its own functions: • Transients in the input and load are reduced by RFI filters. • AC-power is rectified and regulated in the rectifier which provides the power to the inverter and charges the batteries.
- Page 7 Harmonic Control™ with the IGBT rectifier Harmonics cause deviations to the power quality (perfect sinusoidal waveform) and are present in current, voltage or both. Filtering is currently the most common method used to limit the effects that harmonics present to the rest of the system. Traditional filters consist of tuned series L-C circuits.

That is exactly why the Powerware Hot Sync™ technology was developed. An industry leading paralleling technology in its own right, the patented Hot Sync enables you to set up a parallel redundant system giving you 100% conditioned power at all times. Its unique digital design eliminates the system level single point of failure inherent in traditional parallel UPS modules, and exponentially increases the reliability of the overall system. - Page 9 Options The options are used to tailor a matching solution to fulfil the site and load requirements of the installation. The following options are available: • External battery cabinets and racks • External bypass switch cabinets • External bypass isolation transformers •...

Page 10: Safety Information
3. Safety information Since the UPS unit operates on line power and contains a bank of high-current backup batteries, the information in this chapter is important to all personnel involved. 3.1 Storage and transportation Because of the heavy weight of the cabinets and the high energy battery bank the equipment must be handled with care. -
Page 11: Unpacking And Incoming Inspection
If the UPS is not immediately installed the following must be remembered: • The UPS should be stored in the original packing and shipping carton. • The recommended storing temperature is between +15°C ... +25°C. • The equipment must always be protected from dust, moisture and weather. If the UPS is stored for a longer period of time the batteries of the UPS should be charged for at least 8 hours every 6 months to maintain the battery condition. -
Page 12: Installation
5. Installation The UPS unit is designed with all vital parts accessible from front. All cables and protective fuses must be dimensioned according to local regulations. 5.1 Environment All the requirements concerning environment described in this chapter (Installation) or chapter 11 (Technical specifications) must be met. If they are neglected the manufacturer cannot guarantee the safety of personnel during installation or use, or that the unit will function properly. -
Page 13: Floor Loading
5.2 Floor loading When planning the installation the floor loading must be taken into consideration because of the heavy weight of the UPS and battery cabinets. The strength of the installation surface must be adequate for point and distributed loadings given in table 1. Table 1. - Page 14 Figure 5. Connecting UPS and battery cabinets to each other. Adding and removing a temperature sensor of battery cabinets Each battery cabinet has temperature measurement and the cable from battery cabinet has to be connected to terminal block TB5 pins 5 and 6 in user interface area.

If using aluminium shoes, please use anti-oxydizing paste in the connections. The UPS has all the bolts for the power connections. Please check the local safety rules for the installation when designing the cables: Rectifier input Flat copper bar 35*4mm...
- Page 19 Mains and load connections The proper connection order is as follows: Switch off the supply to the distribution point to which the UPS unit is to be connected. For extra safety, also remove the fuses from the selected lines. Make absolutely sure with measurement that there is no power. A readily accessible disconnect device must be incorporated in all fixed input wiring.

Page 35: Selecting Redundancy Or Capacity Mode
8.2 Selecting redundancy or capacity mode A parallel system is parameter selectable (available in 2002) between N+1 redundancy and capacity modes. The parameters are displayed in the LCD control panel. Factory default is the parallel system for N+1 redundancy where user gets an alarm if the +1 redundancy level is exceeded in the load. - Page 36 Recommended cables and fuses All cables and fuses must be dimensioned according to local safety regulations, appropriate mains voltage and the rated current. Table 7. Recommended cables and fuses for the output of UPS modules, ref. SPM9340 wiring diagram of fuse switches S11/21/31/41. Table 8.
- Page 37 System communication with a CANBUS interface A 10-meter CANBUS interconnection cable with termination resistors (2*120 ohm) are supplied for parallel UPS modules. The CANBUS cable must be connected between the TB4 terminals of two successive UPS modules as shown in the earlier wiring diagram of parallel UPS system.
- Page 38 Contact signal from the system bypass switch S51 Parallel UPS system for redundancy or capacity has normally an external make-before- break system bypass switch function installed as shown in the SPM9340 wiring diagram.

Page 39: Starting Up System
An auxiliary contact from the system bypass switch S51 must be provided for each individual UPS module. It’ s connected to the TB2 ‘BUILDING ALARM 3’ terminal and between pins 5 and 6. Figure 18. TB2 signal terminal of UPS modules. Note! Pay attention to the signal polarity because the signal must be the same for all UPS modules. -
Page 40: Switching Off System
Check that the UPS modules have started: - Green UPS ON led is lit if mains power is available, yellow BATTERY led is lit only if the UPS modules are on battery power. Check that yellow BYPASS led is lit in the front panel. This verifies that auxiliary contact signal from the external system bypass switch S51 is ok (refer to SPM9340 design with local tie panels). -
Page 41: System Parallel Module (Spm9340)
8.6 System Parallel Module (SPM9340) A tie panel is needed for the outputs of parallel UPS modules. Powerware’ s optional system bypass module (SPM9340) is a ready-made solution for the maximum system of four parallel UPS modules. It includes four service disconnect switches S11/21/31/41 and a make-before-breake system bypass switch S51. -
Page 42: Maintenance
Note! UPS modules should be transferred to static bypass from the LCD control panel before operating the system bypass switch S51. This procedure ensures UPS modules to check for the internal bypass condition and inverter synchronization. A safe transfer is not guaranteed if the system bypass switch S51 is operated without first transferring UPS modules to static bypass mode. -
