7.14 Testing
Perform the following tests on the Power+ unit.
7.14.1 Blackout Test
This test is designed to verify the operation of Power+ 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 ac input switches to both Bypass and Rectifier).
2. Measure the phase-to-neutral voltage for each output phase. The measurements should all be 120 V
(or as specified).
7.14.2 Cold Start
This test is designed to verify the operation of the UPS after all input power (both mains and battery) has
been shut off and the UPS is powered up with battery only and no ac input.
1. Turn all ac and dc input to the system Off, so that there are no voltages at any of the inputs to the
UPS.
2. Turn On the switch to the dc input (from the batteries) only.
3. Wait approximately 2 minutes for Power+ to initialize (see Section 7.10, First-time Startup ).
4. Measure the phase-to-neutral voltage for each output phase. The measurements should all be 120 V
(or as specified).
5. Turn On the ac inputs to the system.
7.14.3 Test Under Load
This test is designed to verify the operation of Power+ under load.
1. Connect the load.
2. Measure the ac input voltage during operation under load. Take the measurements at the output
terminals of Power+ (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.
3. Check and record the total system load (output current) and make sure that Power+ is not overloaded
with respect to system specifications.
4. Ascertain correct and orderly operation. Verify that Power+ is operating normally and that no alarms
or fault indications are present.
