INV2500 AND INV5000 TELECOM INVERTERS

1.0 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 1 15V AC output at 60Hz. The INV5000 is a 5000V A
inverter which converts a nominal 48VDC input into 1 15 or 230V AC at 60Hz
or 230V AC at 50Hz. The INV2500 comes as a single, stand-alone unit. A 19­inch compatible shelf which can also be mounted in a 23-inch rack and holds
one or two INV2500s is also available. The INV5000 comes in a 19-inch
shelf which can also be mounted in a 23-inch rack. Both the INV2500 and
INV5000 are two mounting positions (3.5 inches) high. See Figure 1.

OPERA TING MANUAL

1.3 The 48VDC nominal input has a range of 42 to 56VDC, and full load output

is 1 15V AC at 22 amperes RMS for the INV2500. For the INV5000 the output
is 1 15V AC at 44 amperes RMS or 230V AC at 22 amperes RMS. The invert­ers achieve 90% efficiency and 7V A per cubic inch power density . Input and
output are both circuit breaker protected. The inverters have high surge
capability for starting loads such as motors, but the output breaker quickly
trips if power attempts to flow back into a faulted inverter.

1.4 These inverters can be paralleled for higher output power or for N+1 redun­dant applications. They are fully isolated from the battery . Front panel LEDs
indicate inverter status, and Form C relay alarm contacts are available on the
back. The units are self-cooled by internal fans.

4.0 SAFETY W ARNINGS

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.

4.3 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 .

5.0 W ARRANTY

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. This warranty
does not extend to products which have been opened, altered or repaired by persons other than

manufacturer’s inspection establishes the existence of a defect. To exercise this remedy, the
buyer must contact the manufacturer’s Customer Service Department to obtain a Return Material
Authorization number and shipping instructions. Products returned without prior authorization
will be returned to buyer. All products returned for repair must be shipped freight prepaid to
UNIPOWER. If the buyer fails to fully comply with the foregoing, the buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost
sales, injury to person or property or any other incidental or consequential losses) shall be

6.0 UNP ACKING AND INSPECTION

6.1 This INV2500 or INV5000 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. The freight
carrier should be notified immediately and a claim for the cost of the rectifier
system should be filed with the carrier for direct reimbursement. Be sure to
include the model and serial number of the damaged unit in all correspon­dence with the freight carrier. Also save the shipping carton and packing
material as evidence of damage for the freight carrier’s inspection.

6.3 UNIPOWER T elecom will cooperate fully in case of any shipping damage
investigation.

6.4 Always save the packing materials for later use in shipping the unit. Never
ship the rectifier system without proper packing.
