No-load/light-load testing. Test the assembled UPS system to verify its capability

6.2.4

to operate continuously under no-load or light-load, as in paragraph 3.3.2.5. The

test duration shall be a minimum of 24 hours.

Surge withstand tests. Conduct surge-withstand capability tests using the

6.2.5

appropriate sections of IEEE C37.90 and IEEE C37.90.1 as a guide. The

surge-withstand test wave shall be oscillatory with a 3000-V crest value in the

first half cycle. The wave shape shall rise from 10 to 90% in 0.5 microsecond,

then decay while oscillating at 100 kHz with each peak being 60% of the

preceding peak as shown in figure 2 of IEEE C62.41.

Field tests. After equipment is completely installed, acceptance tests will be performed by

the Owner to demonstrate performance requirements as specified herein. Any rework

necessary to bring the UPS system into compliance with this specification shall be at

Seller's expense.

Cleaning. At the time of shipment, the equipment shall be clean inside and outside.

Remove all rust, oil, grease, chalk, crayon, and paint marks, and other deleterious material

from all surfaces of the equipment. Touch up any cuts, nicks, or scratches to the coating

system.
