1 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions for models SG Series 50 & 80 kVA that should be followed during installation and maintenance of the UPS and battery. GENERAL - Move the UPS in an upright position in its original package to the final destination room. To lift the cabinets, use a forklift or lifting belts with spreader bars. Check for sufficient floor and elevator loading capacity. Check the integrity of the UPS equipment carefully.
Safety instructions when working with battery EXTERNAL BATTERY MUST BE INSTALLED AND CONNECTED TO THE UPS BY QUALIFIED SERVICE PERSONNEL. INSTALLATION PERSONNEL MUST READ THIS ENTIRE SECTION BEFORE HANDLING THE UPS AND BATTERY. DANGER! Full voltage and current are always present at the battery terminals. The battery used in this system can provide dangerous voltages, extremely high currents and a risk of electric shock. If the terminals are shorted together or to ground they may cause severe injury.
Safety symbols and warnings Safety warnings The text of this manual contains some warnings to avoid risk to the persons and to avoid damages to the UPS system and the supplied critical loads. The non-observance of the warnings reminding hazardous situations could result in human injury and equipment damages. Please pay attention to the meaning of the following warnings and symbols.

3 INSTALLATION 3.1 TRANSPORT Forklift Transport UPS only in upright position! The UPS is packaged on a pallet suitable for handling with a forklift. Pay attention to the center of gravity. The UPS must be moved in upright position. Do not tilt cabinets more than +/- 10° during handling. Move the UPS in it’s original package to the final destination site. Crane Do not stack other packages on top: This could damage the UPS.
3.2 DELIVERY When delivered, inspect the package integrity and the physical conditions of the cabinets carefully. In case of any damage sustained during transport, immediately inform the carrier and contact your local Service Center. A detailed report of the damage is necessary for any insurance claim. NOTE ! A DAMAGED UPS MUST NEVER BE INSTALLED OR CONNECTED TO UTILITY OR BATTERY! 3.3 STORAGE 3.3.
3.4 PLACE OF INSTALLATION 3.4.1 UPS location WARNING ! A qualified electrical contractor must carry out the installation and cabling of the UPS. If optional cabinets and accessories are included with the UPS, please refer to those accompanying manuals for installation and operating instructions. It is important to have a clean, dust-free environment provided with proper ventilation and airconditioning to keep the ambient temperature within the specified operating range.

3.5 VENTILATION AND COOLING Fig. 3.5-1 Installation on plain floor Fig. 3.5-2 Installation on raised floor The heat produced by the UPS is transferred to the environment by its ventilation. Air inlets for UPS ventilation are located on the front of the UPS, while air outlets are on top of the cabinet. A suitable ventilation or cooling system must be installed to extract the heat from the UPS room. NOTE ! Do not put anything on the top of the cabinet.
3.6 UNPACKING The UPS and battery cabinets may be shipped packaged in carton boxes or in wooden crates (if requested). Move the cabinets as close as possible to the final location before removing from the pallet. Remove the cabinet from the pallet with care because of the heavy weight of the equipment. To unpack the cabinet follow the instructions below: 1. Wooden crate will arrive as shown. 2. Remove front and top panels. 3. Let down the ramp “A” and save wood braces “B and C” for ramp supports. 4.
7. Remove anchoring plate “E” from all four legs and unscrew supporting block screws “F”. F 8. F E 9. Divide the supporting blocks with a hammer and save blocks “G” and “H” for ramp supports. Place blocks “G” and “H” and frames “B” and “C” under ramp for support. G 10. H Make sure leveling feet are raised and carefully role UPS down ramp. G H B C NOTE ! Take care not to damage the UPS when moving by forklift.
3.7 ELECTRICAL WIRING WARNING ! UPS installation and connection must be performed by qualified service personnel only. It is the responsibility of the installation technician to ensure that all local and national electric codes are adhered to. 3.7.1 Utility input connection NOTE ! Ensure that the AC and DC external isolators are OFF and locked out to prevent their inadvertent operation. Do not apply power to the equipment prior to the commissioning by a qualified service engineer.
3.7.2 Input/output over current protection and wire sizing The cabling of the UPS system has to be sized according to the UPS power rating. Sizing of circuit breakers, fuses and cables for Input Utility, Output Load and Battery must meet the requirements of local and national electrical codes. Before connecting the UPS, verify that the Utility Voltage and Frequency, the Output Load Voltage and Frequency and Battery Data (cells number, floating voltage, autonomy) are according to the required specifications.
3.7.3 Battery over current protection and wire sizing • • • • Please read the safety precautions at the front of this guide carefully, and thoroughly review the battery manufacturers installation and maintenance manual before connecting the batteries to the UPS. If the UPS system has been purchased with an accompanying battery cabinet, that cabinet should have an integral battery circuit breaker.

3.8.5 Setup for SG Series when functioning as frequency converter When the SG Series is utilized for different output frequency compared to the input frequency, the Automatic Bypass and Manual Bypass functions are disabled, therefore the load cannot be transferred to Utility in case of overload, short circuit, or inverter failure.
3.9 RPA PARALLEL SYSTEM CONNECTION WARNING ! This operation must be performed by trained personnel before the initial start-up. ENSURE THAT THE UPS INSTALLATION IS COMPLETELY POWERED DOWN. 3.9.1 Power wiring of parallel units To guarantee good Load sharing between the units of a parallel system, we recommend that the cable length from the input distribution board (5) to the output distribution board (10) is equal for each unit (a+b = c+d = e+f = g+h = i+l = m+n = o+p = q+r). Tolerance: +/-10%.
3.9.2 Parallel control bus connection In cases of parallel operation, the communication between the units takes place through the control bus cables. Each parallel unit is equipped with an additional board “P13 – RPA Board“ where the connectors J52 (A) and J62 (B) are located. A short control cable provided with a ferrite ring core links the parallel board “P13 – RPA Board” with the parallel bus socket on which must be connected the control bus cables JA and JB on PCB “P34 – Bus Interface”.
