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 5.0 4.3 When operating these inverters, the chassis ground terminal must be connected to safety ground to minimize electrical shock hazard and to ensure low EMI (electromagnetic interference). 4.4 The internal voltages are at hazardous potentials. The inverter covers should not be removed. There are no user-serviceable components in these units. Removing the covers of the inverters will void the warranty.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 6.4 7.0 8.0 Always save the packing materials for later use in shipping the unit. Never ship the inverter without proper packing. DESCRIPTION OF OPERATION 7.1 The INV2500-HS modules employ MOSFET and IGBT power semiconductor switches with advanced, high-frequency, pulse modulation techniques to produce a low-distortion, 50 or 60Hz sine wave output with 90% efficiency and 7VA per cubic inch power density.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 12.0 OPERATING INFORMATION 12.1 Input Voltage. These telecom inverters operate off a nominal 48VDC input source which may be a battery or other DC source. The input voltage range is 42 to 56VDC. Input connections on the back of the INV5000-HS and INVR2U-HS are to bus bars with no. 1/4-20 studs. 12.2 Output Voltage.

After this, the input breaker(s) should be turned back on (up position); after the Output OK LED(s) come on the output breaker(s) should be turned back on (up position). 13.0 12.5 Grounding. The DC input ground, AC output ground, AC neutral and chassis ground are all in common.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL more inverters. Current sharing between paralleled inverters is ±10%. 13.2 Alternatively, separate sources may be used for the inputs to these inverters while the outputs are connected in parallel. In either case, output loads should have individual distribution circuit breakers. The following table shows output current and total volt-amperes for inverters connected in parallel.

INV2500-HS & INV5000-HS SERIES OPERATING MANUAL by means of the 1/4-20 studs. Connect the input ground (10-32 stud) to the system ground. Make sure the correct polarity is used and make sure the connections are clean and firm. Reversed input polarity could cause damage to the inverter. 15.0 14.4 Connect the AC output cable to the proper output screw terminals. See Figure 10 for the correct connection for 115 or 230VAC output versions.
INV2500-HS & INV5000-HS SERIES OPERATING MANUAL 16.0 15.3 Take one of the inverter modules and turn the DC input circuit breaker on; then after the Output OK LED has come on turn the AC output circuit breaker on. This sequence must be performed for the inverter A side and then the B side. Repeat this for each paralleled inverter in turn until all inverters are on. Make sure that the three green LEDs are on for each inverter. 15.
