Wiring Access

Two areas house the system wiring. The BOS compartment opens with a latch. It connects

to external wiring (battery, AC, PV, etc.) and conduit. These connections extend from the

BOS into the SkyBox compartment, which opens with two Allen screws (K). If the SkyBox

must be removed for service, the BOS and its wiring can remain. Some connections, such

as communications, pass through the BOS to be made directly in the SkyBox.
