Extreme caremust be used when taking measurements on the controlboard. Any AC powered instruments must be groundisolated prior to taking measurements. A ground isolatedinstrument case will be at the high voltage line potential.Measurement procedureVerify the L–N for each phase is ±3% of the nominalvoltage. If the voltage measurement is out of range,consult factory.Parts kitsTable 5. 50 and 60 Hz, all voltageskVA size Kit price (U.S. funds)10 kVA Consult factory15 kVA Consult factory25–50 kVA Consult factory75 kVA Consult factory100–125 kVA Consult factory150 kVA Consult factory225 kVA Consult factory300 kVA Consult factory500 kVA Consult factoryotes:N Each parts kit includes the following:(7) Power modules (SCRs)(3) Semiconductor Fuses(1) Fusible link (for one full phase)(2–4) Fan motors (depending on unit size)(1) SCR snubber board(3) Sense fuses(1) Main control boardReplacement partsIndividual components are also available upon request.Please contact the factory for specific part numbersand prices.
