OPERATING MANUAL

1.0 INTRODUCTION

1.1 This Operating Manual should be read through carefully before installing and operating

the INV2500-HS inverter modules and shelves. See Figure 1.

1.2 The INV2500-HS is a 2500 volt-ampere, hot-swap, DC to AC inverter module. It con-

verts a nominal 48VDC input into a 115 or 230VAC output at 50 or 60Hz. These mod­ules are designed to go into a 19-inch, hot-swap compatible shelf, INVR2U-HS, which
holds one or two units. When two modules are used in this shelf they are automatically
connected in parallel and synchronized to produce 5000 volt-amperes at 115VAC output
(44 amperes) or 230VAC output (22 amperes). Or they can be operated in a 1+1 redun­dant mode at 2500 volt-amperes.

1.3 The 48VDC nominal input has a range of 42 to 56VDC. The inverters achieve 90% ef-

ficiency and 7VA per cubic inch power density. Input and output are both circuit breaker
protected. They have high surge capability for starting loads such a 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 applica-

tions. 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.

1.5 In this manual, unless otherwise stated, INV2500-HS shall generally refer to both

INV2500-HS and INV2500H-HS (115 and 230VAC) inverter models. Likewise INVR2U­HS shall generally refer to both INVR2U-HS and INVR2U-HS-H shelf models.

NOTES:

1. Add Option Code as suffix to module model number.

2. This option is for 115VAC models only. The standard 115VAC models have neutral internally
connected to ground/case.

3. The standard 230VAC modules have a floating neutral.

4.0 SAFETY WARNINGS

4.1 These inverters have hazardous external and internal voltages. They should be han-

dled, 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 re-

moved. There are no user-serviceable components in these units. Removing the covers
of the inverters will void the warranty.

4.5 WARNING: When using “floating neutral”, Option E on the INV2500-HS module or

standard on the INV2500H-HS module, the AC neutral output terminal “N” is float­ing with respect to AC and chassis ground. A neutral-to-ground connection must
be re-established external to the inverter and be in compliance with the require­ments of the end-use application.

5.0 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. This warranty does not
extend to products which have been opened, altered or repaired by persons other than persons autho­rized by the manufacturer or to products which become defective due to acts of God, negligence or the

This warranty is extended directly by the manufacturer to the buyer and is the sole warranty applicable.
EXCEPT FOR THE FOREGOING EXPRESS WARRANTY, THE MANUFACTURER MAKES NO WAR­RANTY, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE WARRANTY OF MER­CHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. As the sole and exclusive remedy
under this warranty, the manufacturer, at its option, may repair or replace the non-conforming product
or issue credit, provided the 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 available to the buyer.
