• To connect the interface to the system controller and/or ME remote controller, connect the M-NET communication cable to
TB520 (non-polarized).
Connect the 2-core communication cable to A1&B1 or A2&B2. (It does not matter which pair of connectors is used.)
• Connect the shield wire of the connecting cable to the S terminal only when the daisy chain method is used to wire the com-
munication cable.
• M-NET communication cable should be located as far away from other power supply cords as possible. Placing them closely
could cause a malfunction.
• After wiring is complete, fi x each cable with the cable clamps, and attach the cable ties as shown in the fi gure.
(3) Connecting the M-NET communication cable
● For connection of the MA remote controller, connect the MA
remote control cable to TB580 (non-polarized).
● When more than one unit of room air conditioner is operated
in group control, use the daisy chain wiring method by con-
necting the MA remote control cable to TB580.
(4) Connecting to the MA remote controller
• Before performing the following procedures, turn off the main power to the
air conditioner and all systems.
• If the connecting cable is not securely fi xed, the connector may come off,
and the interface could break or malfunction.
• The unit will not operate normally if the dip switches (SW500, SW502) and the
rotary switches (SW501, SW510, SW580) on the interface unit are not set cor-
rectly.
• Replace the cable clamp according to the size of the connecting cable used
for each system. Fasten the cable tie as shown in the fi gure to prevent undesirable movement of the connecting cable.
