[2] Connector for Communication
It is the connector to monitor the status data inside the power source by communication.
There are two inlets in order to enable communication with multiple power sources in
multi-drop wiring.
It can be connected to either of the inlets because the differential signal
on each inlet is short-circuited with each other inside. The connector on the cable is
enclosed.

*1 LED lamp should be off when the fan is not connected.
*2 There may be a case that this LED lamp is off even if there is an input of AC power when
in parallel operation in low load as there is a case that only some of the power sources are
in operation. It should turn on when load increases and all the power source starts
working.
