Simplex 734-012 — harness carrying AC and battery connections from a 120 V power supply board to the Power Distribution Module in 4100U and 4100ES panels.
PDM stands for Power Distribution Module, the chassis part that takes incoming AC and battery power and distributes it through the panel bays. Each supply board is tied to the PDM by a factory harness rather than by field wiring, and this is the 120 V version of that link.
- Simplex description: Harness, SPS/RPS/XPS/TPS to PDM AC/Battery, 120 V
- Serves the System, Remote, Expansion and TrueAlert Power Supply boards
- Connects to the 120 V Power Distribution Module, Simplex 4100-0634
- Service part in the 4100U list 579-330 and the 4100ES list 579-1006
- Carries AC and battery conductors in one pre-terminated assembly
Confirm supply voltage first: 734-013 is the same harness built for 220 V panels and the 4100-0635 PDM. Distinct are 734-015 and 734-091, which run PDM to battery and to the PDM varistor, 734-008, the PDI bay-to-bay power harness, and 734-049 and 734-050, used when fitting these supplies into a legacy 4100 box.
