INV2500 & INV5000 SERIES OPERATING MANUAL INV2500 AND INV5000 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 or INV5000 Series inverters. 1.2 The INV2500 is a 2500 volt-ampere telecom inverter which converts a nominal 48VDC input into a 115VAC output at 60Hz. The INV5000 is a 5000VA inverter which converts a nominal 48VDC input into 115 or 230VAC at 60Hz or 230VAC at 50Hz.

INV2500 & INV5000 SERIES OPERATING MANUAL 4.4 5.0 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. WARRANTY All products of UNIPOWER Telecom, a division of UNIPOWER Corporation, are warranted for two (2) years from date of shipment against defects in material and workmanship.
INV2500 & INV5000 SERIES OPERATING MANUAL 7.0 8.0 DESCRIPTION OF OPERATION 7.1 The INV2500 and INV5000 Series 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. A synchronization circuit lets two or more inverters operate in parallel with their outputs in phasesynchronization and current shared. 7.

INV2500 & INV5000 SERIES OPERATING MANUAL terminals for the INV5000. 12.3 Output Power. Maximum output power for an INV2500 is 115VAC at 22A RMS giving a maximum of 2530 volt-amperes. For an INV5000 it is 115VAC at 44A or 230VAC at 22A RMS, giving a maximum of 5060 volt-amperes. Exceeding these values may cause electronic shutdown of the output. Full output power is produced at up to 50oC ambient temperature. Above this, output current must be derated at 2.5%/oC.

Note that for the INV5000 there is a separate set of contacts for each half (A and B sides) of the inverter. If it is desired to monitor the INV5000 as a whole, the two sets of contacts may be connected as shown in Figure 7 to give an OR function for either set of contacts. 12.8 13.0 Connector Kit.

INV2500 & INV5000 SERIES OPERATING MANUAL 13.4 14.0 Figure 10 shows two INV5000s connected in parallel to give 10KVA of AC output at 115VAC. Note that only 115VAC INV5000s can be used with the DPAC1UT distribution panel and not the 230VAC INV5000s. 230VAC INV5000s require breakers on both line sides, and this is not available with the DPAC1UT. As with the INV2500, the input ground, output ground, chassis ground and AC neutral are all connected in common inside the INV5000 inverter.

INV2500 & INV5000 SERIES OPERATING MANUAL come on followed by the Output OK LED approximately four seconds later. After the Output OK LED is on, turn on the AC output circuit breaker by placing the toggle in the up position. Check the AC voltage across the load with a digital AC voltmeter. The voltage should be between 115 and 120VAC depending on the amount of load. 15.0 14.6 To power up the INV5000, turn the A side (left) DC input circuit breaker on by moving the toggle to the up position.
INV2500 & INV5000 SERIES OPERATING MANUAL 16.0 15.3 Take one of the inverters 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 INV5000 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. 15.4 With all inverters on, turn on each AC output distribution circuit breaker.
INV2500 & INV5000 SERIES OPERATING MANUAL 17.0 16.4.2 Install the replacement inverter in the shelf, rack or other mounting. 16.4.3 Reconnect the AC output connections. 16.4.4 Carefully reconnect the DC input connections (these are hot!) See CAUTION in paragraph 16.2. 16.4.5 Reconnect the sync BNC connector and the Form C relay contact wires. 16.4.6 Turn on the DC input breaker (A side breaker for INV5000). 16.4.
