INV2500-HS AND INV5000-HS TELECOM INVERTERS

1.0 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 1 15V AC 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 units are used in this
shelf they are automatically connected in parallel and synchronized to pro­duce 5000 volt-amperes at 1 15V AC output (44 amperes). Or they can be
operated in a 1+1 redundant mode at 2500 volt-amperes.

1.3 For 230VAC output at 50 or 60 Hz there are two other inverter models, desig-

nated INV5000-HS-230, which use two INV2500-HS units connected in
series in their shelf to give the higher voltage. See the product line designa­tion in Section 3.0. The output is 230V AC at 22 amperes, or 5,000 volt­amperes.

1.4 The 48VDC nominal input has a range of 42 to 56VDC. The inverters achieve
90% efficiency and 7V A per cubic inch power density . Input and output are
both circuit breaker protected. They 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.

1.5 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.

3

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
persons authorized by the manufacturer or to products which become defective due to acts of
God, negligence or the failure of customer to fully follow instructions with respect to installation,
application or maintenance. 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.

6.0 UNP ACKING AND INSPECTION

6.1 This INV2500-HS or INV5000-HS was carefully tested, inspected and pack-

aged 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 inverter
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.
