CBE PC180 Control Panel connections

The PC180 is a control and display panel, not the battery distribution box or mains charger. CBE's product page identifies the panel, while the downloaded PC180-ST/DS300-ST manual, page 11, distinguishes the panel, DS300 distribution equipment and separate CB-series charger. The available detailed manual is the ST family revision; confirm the OEM panel and DS300 labels before applying its pinout or behavior to a PC180 installation.

The single DS300 panel harness terminal represents the 16-pole panel connector on page 15. It is a signal/harness dependency, with no modeled load current and no direct battery connection. It is not permission to wire battery positive to an arbitrary panel pin. Use the matching harness and connector orientation for the actual hardware revision.

The panel's own current is not separately specified in the reviewed manual, so it is not fabricated from a DS300 branch fuse. Battery feeds, pump and lighting fuses, starter/house interconnection and charger wiring belong to their respective DS300 and charger components. They are deliberately absent from this panel symbol.

The control overview, page 12, describes the main switch, pump and awning-light controls, battery tests and tank indication, with indicators for mains and alternator operation. These controls command the matching distribution system; their presence does not establish which optional loads are installed in a particular vehicle.

The ST operating description, page 13, describes battery-voltage alarms and a low-battery load cutoff. The stated thresholds include B1 warning below 12 V, B2 below 11 V and selected-load disconnection at 10 V. This is voltage-based behavior, not a lithium state-of-charge estimate. Some loads, including designated refrigerator, step and direct-battery circuits, are excepted.

For a dead display, first check the associated DS300 supply, fuses and correctly seated panel harness. For a failed pump or lamp, trace that load through the DS300 rather than assuming the panel itself supplies its current. The DS300 charging description, page 16, includes starter charging and alternator-related functions that vary with system revision. Smart-alternator or DC-DC charger conversions require the specific manufacturer's system instructions; do not improvise relay changes from a panel diagram.
