INV2500-HS & INV5000-HS SERIES OPERATING MANUAL INV2500-HS AND INV5000-HS TELECOM INVERTERS OPERATING MANUAL 1.0 2.0 INTRODUCTION 1.1 This Operating Manual should be read through carefully before installing and operating the INV2500-HS inverter modules or INV5000-HS inverter systems. See Figure 1. 1.2 The INV2500-HS is a 2500 volt-ampere hot-swap, telecom inverter module. It converts a nominal 48VDC input into a 115VAC output at 50 or 60Hz.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 4.0 5.0 SAFETY WARNINGS 4.1 These telecom inverters have hazardous external and internal voltages. They should be handled, tested and installed only by qualified technical persons who are trained in the use of power systems and are well aware of the hazards involved. 4.2 The input and output terminals are at hazardous voltage potentials. Do not touch these areas when power is applied. 4.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 6.0 7.0 UNPACKING AND INSPECTION 6.1 This INV2500-HS or INV5000-HS was carefully tested, inspected and packaged for shipment from our factory. Upon receipt of the unit, it should be carefully unpacked and inspected for any damage in shipment. 6.2 If there is evidence of damage, do not attempt to test the unit.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL modules in an INVR2U-HS shelf are both 5,000 VA inverter systems and will be referred to as an INV5000 where the generic meaning is conveyed. While the two different shelves are identical in size and appearance, they differ in their internal module connection (series or parallel). 8.0 9.0 FRONT AND BACK PANEL DESCRIPTIONS 8.1 Figure 2 shows the front and back of an INV2500-HS inverter module.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 11.0 SAFETY AND INDUSTRY STANDARDS 11.1 12.0 The INV2500-HS and INV5000-HS inverters meet the following safety certifications: STANDARD AGENCY UL1950 CSA22.2 No.950 EN60950 UL CUL DEMKO 11.2 The INV2500-HS and INV5000-HS inverters are CE marked to indicate conformance to the European Union’s Low Voltage Directive. 11.3 Input conducted EMI meets FCC20780 part 15J Curve A and EN55022 Curve A. 11.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 12.4 Overload Characteristic. These inverters incorporate electronic shutdown circuitry; shutdown takes place during an overload, before the output circuit breaker trips. Figure 5 shows INV2500-HS output voltage and current waveforms for a full load step, sudden overload, and short circuit. Figure 6 shows shutdown time versus output current for both the INV2500-HS and INV5000HS. Below is a table that shows the same data in a different format: Table 12-1.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 13.0 12.8 Sync Connections. There are +Sync and -Sync terminals on the terminal block. When two or more inverters are connected in parallel these Sync terminals must be connected together, observing the polarities. 12.9 Inverter Module Connections. If the INV2500-HS inverter module is operated or tested separately from the shelf, connections should be made to the J1 connector with a mating connector and the pin connections given in Figure 8.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 13.4 14.0 Figure 9 shows four INV2500-HS inverter modules in two INVR2U-HS shelves connected in parallel to give 10KVA of AC output at 115VAC. The AC output is distributed by a DPAC1UT AC Distribution Panel made by UNIPOWER Telecom. Note that only 115VAC inverters can be used with the DPAC1UT distribution panel and not the 230VAC INV5000-HS. 230VAC INV5000-HSs require breakers on both line sides, and this is not available with the DPAC1UT.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL later. After the Output OK LED is on, turn on the B side AC output breaker. Check the AC voltage across the load with a digital AC voltmeter. The voltage should be between 115 and 120VAC or between 230 and 240VAC, depending on the model. 15.0 14.6 Check the Form C Relay contacts with an ohmmeter. See Figure 3. Measure the resistance between the N.O. contacts and C contacts. They should indicate an open. Measure the resistance between the N.C.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 16.0 REPLACING AN INVERTER MODULE 16.1 The following instructions are for replacing an INV2500-HS inverter module in an INVR2U-HS shelf. 16.2 The inverter module may be field replaced only in an INVR2U-HS shelf, i.e., when it is parallel connected for 115VAC output. For the INV5000-HS inverters, the replacement must be done at the factory due to the complexity of the series connection of the inverter modules. 16.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 17.0 MAINTENANCE No routine maintenance is required on the INV2500-HS or INV5000-HS Series inverters except for a periodic cleaning of dust and dirt around the front fans and rear ventilation holes. A small vacuum nozzle should be used for this. 18.0 TROUBLESHOOTING GUIDE 18.1 If you encounter difficulty in getting the inverter(s) to operate, go through the following troubleshooting guide. 18.2 Table 18-1.
