1. Air conditioning-related equipment comprising:
a first connection portion to which a high-voltage power line is connected, the high-voltage power line including a power line for transmitting high voltage, a signal line for communication, and a shared line shared for high-voltage transmission and communication;
a second connection portion to which wiring dedicated to communication and not to power transmission or wiring for transmitting low voltage along with communication is connected; and
a connection circuit that connects the first connection portion and the second connection portion,
wherein
the first connection portion
is for connecting to other external air conditioning-related equipment via the high-voltage power line,
the second connection portion
is for connecting to other external air conditioning-related equipment via the wiring dedicated to communication and not to power transmission or the wiring for transmitting low voltage along with communication,
the connection circuit includes
a communication circuit that communicates via the high-voltage power line, and communicates via the wiring dedicated to communication and not to power transmission or the wiring for transmitting low voltage along with communication, and
an isolation circuit provided in front of the communication circuit, the isolation circuit blocking high-voltage power and transmitting a signal pertaining to communication,
the first connection portion is connected to the communication circuit via the isolation circuit, and
the second connection portion is connected to the communication circuit without the isolation circuit interposed.
