Connectors

Twenty-six connectors to interface with external equipment as follows:

•P1 to P24: signaling between the controller and the rectifiers

•P25: interface with the main power system shunt

•P26: interface with an AC monitoring device

Refer to Figure 31 for the pin assignment of connectors P1 to P26.

Eight connectors (J1 to J8) for the interface between the two circuit boards of the controller (for factory use only).

4.3MPS300 and MPA100 Power Shelves

The MPS300 power shelf provides the interconnecting points for all the AC, DC and control cabling and wiring for three Helios Rectifier 100/48. The MPA100 power shelf does the same for one Helios Rectifier 100/48.

Refer to the appropriate rectifier user manual listed in 6.0 - Reference Documents for detailed operation information on the MPS300 and MPA100 power shelves.
