Start Up the PDU
Contact Schneider Electric to schedule the first start-up of the PDU. Only qualified personnel must handle or operate the equipment.
Follow these steps any time that the system is restarted after having been shut completely down with no power applied to the system.
- Verify the following before starting the PDU:
- The upstream input breaker is in the OFF position.
- The power cables have been correctly connected to the main input breaker MIB/main input switch MIS.
- Voltage connected to the PDU matches the PDU nameplate and model number.
- All equipment has been properly grounded.
- All power cables and signal cables are installed correctly.
- All ventilation areas are free for obstructions that might impair proper airflow.
- Close the upstream input breaker.
- Close the main input breaker MIB/main input switch MIS.
- Verify the function of any installed power meters.
- Close the main output breaker MOB, if present.
- Close the individual branch breakers as required.
Verify normal operation of the PDU immediately after the start-up has been performed.
Use the display and power meters (if present) to verify proper readings from all circuits.
Follow the note for installers when performing a temperature test during commissioning: The PDU complies with the UL standard. The expected temperature deviation at the measuring location between cables, busbars, and main input device MID terminal connections across the three phases is acceptable up to a maximum limit of ±10 °C (±18 °F).
