Testing
Perform the following tests on the MegaV2 250 unit.
1.4.1
Blackout Test
This test is designed to verify the operation of MegaV2 250 in the event of a blackout, when no
ac power is supplied to the UPS.
1.
Turn all ac input to the system OFF (turn OFF the ac input switches to both Bypass and
Rectifier).
2.
Test the voltage at the system output between the phases and the neutral. It should be
within the specified range.
1.4.2
Test Under Load
This test is designed to verify the operation of MegaV2 250 under load.
Connect an average or standard load to the system.
1.
Measure the ac input voltage during operation under load. Take the measurements at
2.
the output terminals of MegaV2 250 (phase-to-phase between L1-L2, L2-L3, and L3-
L1 and phase-to-neutral at L1, L2, and L3). Phase-to-phase and phase-to neutral
voltage should be not less that 2% below no-load values.
Check and record the total system load (output current) and make sure that
3.
MegaV2 250 is not overloaded with respect to system specifications.
Verify that MegaV2 250 is operating normally and that no alarms or fault indications
4.
are present.
1.4.3
Check IP Communication with Controller
This test is designed to verify that the System Controller is properly configured for communication
and that the Web server built-in into the System Controller is functioning properly. If you do not
intend to use remote monitoring and control of the MegaV2 250 you can skip this test at this time.
Use an RJ45-to-RJ45 crossed cable to attach a notebook to the Ethernet (RJ45) port
1.
on the rear panel of the System Controller.
Configure the Network Connections of the notebook to make sure the computer is in
2.
the same domain as the UPS (Note: The details of the following configuration
procedure are for the Windows XP operating system). The configuration procedure
will differ for other operating systems.)
