Abstract
In an active mode, a controller switches an operation mode from the active mode to a suspend mode when an acceptance preparation completion signal is not received from downstream or when a circuit board is discharged downstream, if a discharge preparation completion signal has not been received from upstream. The controller controls relay apparatuses and adjusts a flow of current to control units, in addition to controlling its own CPU clock frequency.
