11.3.4 X303 Battery Terminal
A cable harness is required to connect batteries to the periphery board. The battery
connector end that goes on the periphery board at X303 can only connect one way
because it is keyed.
The battery connection is only made once the whole system has been configured
through jumpers and modules, and after AC has been applied.
