INV2500-HS SERIES
MANUAL
6.0 UNPACKING AND INSPECTION
6.1
This INV2500-HS or INVR2U-HS 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 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 car-
ton and packing material as evidence of damage for the freight carrieir’s inspections.
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 in-
verter without proper packing.
7.0 DESCRIPTION OF OPERATION
7.1
The INV2500-HS modules employ MOSFET and IGBT power semiconductor switches
with advanced, microprocessor controlled, 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-synchronization and current shared.
7.2
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 or 230VAC output
at 5,000 volt-amperes.
8.0 FRONT AND BACK PANEL DESCRIPTIONS
8.1
Figure 2 shows the front and back of an INV2500-HS inverter module. On the left side
of the front panel of the INV2500-HS is the input circuit breaker. To the right are the two
cooling fans and the output circuit breaker. Above the output breaker from the top are
the green LED indicators for Input OK, Sync OK and Output OK.
8.2
On the INV2500-HS back panel on the right side is the hot-swap connector which con-
tains all power and signal connections.
8.3
Figure 3 shows the front and back of an INVR2U-HS or INVR2U-HS-H shelf. Each half
of this shelf (side A or B) has an INV2500-HS. The back panel INV2500-HS has a trans-
parent plastic safety cover. The INVR2U-HS shelf with two INV2500-HS inverters in it
has a front retention panel over the inverter modules.
