The device is consisted of a monitor and a terminal. The monitor is installed on the side
of ship normally in the Medium Voltage Shore Connection device. And the terminal is
installed on the side of shore normally in the dock transformer cabinet or distribution cabinet.
Each monitor needs to be paired with a terminal for use.
