Use an ohmmeter to verify continuity between TB2 (or TB3) on the power entry panel and the AC terminal connections on the PMU backplane. 14. Verify the circuit breakers on the PEP panel are in the off position.

    APPENDIX E - IEPAS01/IEPAF01 POWER MODULE REPLACEMENT INTRODUCTION The IEPAS02 and IEPAF02 power modules are compatible replacements for the IEPAS01 and IEPAF01 power modules respectively. The IEPAS02 and IEPAF02 modules have design enhancements and features that are not available in the previ- ous power modules.

  • Page 96: System Effects On Module Leds

    IEPAS01/IEPAF01 POWER MODULE REPLACEMENT ® The IEPAS01 module output voltages are factory adjusted at full load conditions. These output voltages can show minor changes because of loading, temperature, component aging, and environment. The IEPAS02 power module does not require factory calibration, and will automatically adjust its outputs to compensate for changes that affect the output voltages.
