INV2500-HS & INV5000-HS SERIES
OPERATING MANUAL
6.0 UNPACKING 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 Telecom 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 inverter without proper packing.
7.0 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. A synchronization circuit lets two or
more inverter modules operate in parallel with their outputs in phase-synchro-
nization and current shared.
7.2 The INV5000-HS inverter system consists of two INV2500-HSs operated in
series for a 230VAC output at 5,000 volt-amperes (22A). The series connec-
tion of the units is made internally in the shelf. Each of the two inverter mod-
ules has its own input and output breakers, indicator LEDs and Form C relay
contacts. The two inverter modules in the INV5000-HS are different in that
their outputs are 180
o
out of phase with each other. Therefore these modules
must not be hot-swapped by the user.
7.3 Two INV2500-HS inverter modules in an INVR2U-HS shelf are automatically
connected in parallel in the shelf and become an inverter system with a
115VAC output at 5,000 volt-amperes (44A).
