6.Connecting the M-NET Interface, the Power Supply, and the ME Remote Controller

•When connecting the unit to a system controller or ME Remote Controller, connect the transmission line of the M-NET to the control signal terminal.

Connect the 2-core connection wrings A to A1/B1 or A2/B2 (they can be connected to either).

•Cross the shield portion of each connecting wire using the S terminal only when cross wiring the connection wires.

•When connecting the connection wrings A and the ME Remote Controller connection wrings B to the terminal board, there is no need to worry about polarity.

Make sure the cut surface is free of any burr so that the connection wire dose not get damaged.

Caution

•Electrical work should be performed in accordance with the Technical Standards Regarding Electrical Equipment and the Interior Wiring Standards.

•Connection wiring and remote control wiring should be located as far away from other electrical wiring as possible. Placing them too closely together could cause a malfunction.
