initiated transfer shall also be possible.

If the bypass power is within the tolerances specified in section 4.2, the presence of the static switch shall make it
possible to use the short-circuit pow er of th e bypa s s source to t rip th e down st ream prot e cti on de vi ces of the
inverter.
To ensure tripping in a selective manner, the available power shall be sufficient to trip protection devices with hig h
ratings (circuit breaker rated In/2 or UR fuses rated In/4, where In is the rated inverter current).
If the bypass source is outside the specified tolerances, the inverter on its own shall, for the same discrimination
requirements, be capable of tripping circuit breakers rated In/2 or UR fuses rated In/4, irrespective of the type of
short-circuit.

13. Quality system and test procedures
13.1. Test procedures
The manufacturer shall provide proof of a quality-assurance system. In particular, the main manufacturing steps
must be subject to suitable tests such as:
(cont.)
APC by Schneider Electric Edition - 01/2010 Single UPS spec - p.
10
Specification guide
Single UPS, three-phase, 160 to 500 kVA
ω Inspection of incoming components, tests on discrete subassemblies
ω Complete functional checks on termination of manufacture.
The equipment shall be subject to burn-in under load conditions prior to shipping.
Final checks and adju stments shall be recorded in a report drafted by the quality-inspection department of the
supplier.
Certification of the industrial facilities in complia nce with ISO 9001 or 9002 shall be required.
13.2. Quality system

ω Level one: simple checks and settings, procedures ac cessible without any dismounting and involving no risk.
ω
Level two: preventive maintenance, checks no t inh ibiting continuous operation of the system and prepa ring
operators for Manufacturer services.
Level three: trouble-shooting. Repairs by standard exchange of subassemblies and functional power and control
ω
components. Preventive-maintenance operations, both systematic and when indicated by qualified diagnosis.
Level four: major preventive and corrective maintenance operations or technical upgrades during start-up,
ω
operation or renovation of the UPS installation and recycling of equipment or components representing a risk.
These operations require the use of devices and means that have been calibrated by certified organizations.

the customer site in view of reducing the mean time to repair (MTTR). The supplier shall be in a position to offer a
contract limiting the re sponse time to four hours.
ω The supplier's logisti cs system and the availability 24 hours a day of original replaceme nt parts shall similarly
contribute to reducing to the greatest extent possible the mean time to repair (MTTR).
14.4. System start-up
The system and equipment shall be star te d up on sit e by the sup pl i e r or its auth o ri zed age nt . The pro ced u re sh all
