All the work performed in this section must be performed or witnessed by a Eaton ServiceRepresentative.The commissioning sequence is as follows:1. Before applying input power to the STS, the Installer and the Eaton Service Representative shouldperform the following checks:a. Verify that the incoming power matches the unit rating (building electrical service and voltage) matchthe unit rating and the TFA STS Bill of Materials.b. Check the customer connections to input and output buses.c. Verify that the STS is connected to the grounding electrode conductor.2. Open all MCSWs in the STS.3. Apply power to the unit by energizing the building power circuit breaker or UPS output circuit breakersupplying the TFA STS unit.4. Perform the following measurements:a. Incoming voltage at input to the STS unit should match the unit rating (-10% to +5% of nominalrating).b. Check for correct phase rotation (clockwise) and voltage at the Source 1 Power Input bus.5. With all MCSWs open, verify input phasing is correct by verifying these measurements:a. Zero volts between the phase A poles on the line side of all input MCSWs.b. Zero volts between the phase B poles on the line side of all input MCSWs.
