Before starting a unit some basic rules should be respected, in order to avoid injury or damage. After placing the UPS(s) at it's final destination and having it unpacked, remove the side- and protection panels. With access to all parts, a thorough mechanical inspection should ensure the unit(s) has no damage or loose bolts, screws, nuts or cables. Remove transit brackets. Insure that the transit brackets and bolts on all transformers and inductors have been removed. These brackets and bolts are bright yellow in color. Connect then all Input / Output cables according the instructions in the operating manual. Inspect fans, insure that the fans spin freely. Check all fuses ohmically.Use thecommissioning report, to take note of checked items and measured values during commissioning.Note: If any problems with this installation are found that pose a threat to persons or equipment, do not proceed until the problem has been corrected. Make sure all breakers are open (Q1, Q2, Q3a, Q4) then connect Mains voltage to the UPS (both if separate for Rectifier andBypass). Power supply starts a the display shows a selftest, at the end of which should result "Self test ok". Verify inParametersfor correct Date and Time. Verify in the Service Alarms for the presence of the code 9D04, which indicates the correct function of important parts of the control board IM 0007.In case you find codes 9D00, 9D01, 0D02, 9D03 instead, a malfunction on the control board is present. Change the control board !!Warning:Main Input Feed CB is closed and thus supplying LETHAL voltages to the system. Caution:It is recommanded that the load supplied by the UPS remains OFF until commissioning has been completed. Verify for correct phase rotation onpower interface IM 8820orIM 0035. Measure and record all Power supply voltages onPower supply board IM 8845orIM 0076. Verify correct Power wiring. In a parallel system the outputs of all units must be connected. (Customers load not yet connected)Close Q2 on 1st Unit.Measure on 1st Unit with Voltmeter Phase L1 Mains - Phase L1 Load connection, followed by the phases L2 and L3. Measure then the same on all other units in case of a parallel system. Should you measure voltage you may have a miss wired output. Open Q2.Commisioning reportSubjectDescriptionPassedYesNo

Low voltage startup

In many occasions it might be useful to test the function of Rectifier and Inverter with a voltage low enough to avoid damage in case of malfunction, in particular to the power modules, before running the UPS in nominal voltage. Find below a description for how to proceed.Important:At the end of Low voltage startup the UPS must be shutdown completely, including power supply, to reset some Parameters to their original value. Open Q1 and Q4, disconnect Battery Connect Mains (Utility power) to the UPS. Enter third level Parameters, (seePassword) and change the values of the following 2 Parameters:- Parameter 217: 21000 (17300 in case of 12 - pulse Rectifier !!!) (Reduces the Rectifier output voltage)- Parameter 112: 00050 (Limits the Inverter voltage to 50 Volts) Connect a Voltmeter to the DC - Link (UDC) and an Oscilloscope to the Inverter ouput. Close Q4 to start the Rectifier. The DC Voltage should now gradually increase.See table below. Press now the key Inverter ON. As the Inverter starts, the DC Voltage decreases while the AC Voltage of the Inverter should be a clean sinewave. If everything looks ok, proceed and increase gradually the DC Voltage by reducing the value in Parameter 217, until you reach again the previously installed default value (4000).See in the table below the resulting voltages (approximate !!!). Att. Switch Inverter and Rectifier OFF (open Q4) before changing Parameter 217. An example of the approximately resulting voltages is shown in the table below. Should at any time of the procedure result a deformation of the Inverter output sinewave, do not continue, but check first for correct drive pulses of Rectifier and Inverter. If necessary change the Main control board IM 0007 / 0057 or one of the driver boards. SetParameter 112for nominal Inverter output voltage. (230V).Important: At the end of the procedure you must either shut down the UPS completely, including power supply, or make a reset withPB2on the main control board IM 0007, always with DC - Capacitors discharged !!!!!!With 6 - Puls Rectifier and 50Hz !!!Parameter 2176 - PulsUDC with Inverter OFFUDC with Inverter ONU Inverter

The values shown in this table are indicational, in particular the values in Parameter 217 should be choosen on dependence of an actual existing problem !!!

Once the Rectifier is running at floating voltage, stop the Inverter and change Parameter 112 for the Inverter output voltage, back to it's nominal value.
