1. Use separate power supplies for the outdoor unit and connection kit.
2. Consider the ambient conditions (ambient temperature, direct sunlight, rain, etc.) when wiring and making connections.
3. The wire size is the minimum value for metal conduit wiring. The power cord size must be 1 rank thinker in consideration of voltage
drops.
Make sure that the power supply voltage does not drop more than 10%.
4. Select non-fuse breaker (NFB) or earth leakage breaker (NV).
(A means for the disconnection of the supply with an isolation switch, or similar device, in all active conductors shall be
incorporated in the fixed wiring.)
5. Power supply codes of appliance must not be lighter than design 60245 IEC 53 or 60227 IEC 53.
6. A switch with at least a 3 mm contact separation in each pole must be provided by the air conditioner installation.
Power cable size : more than 1.5 mm

Warning:
• Be sure to use the specified wires for connection so that no external force is imparted to the terminal connections.
If the wires are not securely connected, a fire can occur.
• Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some
amount of direct current.
Caution:
• Some installation sites may require a ground-fault interrupter. If a ground-fault interrupter is not installed, an electric
shock can occur.
• Use only a circuit breaker and fuse of the specified capacity. Using a fuse and copper wire with excessive capacity can
cause a malfunction or a fire.
• The temperature set at the last operation takes priority by operating the system controller, MA/ME remote controller, or
local remote controller.
When connected to a CITY MULTI indoor unit in a system
M-NET system remote controllers cannot be used to operate the indoor unit that is connected to the connection kit.
<Restrictions>
1. The indoor unit to which the connection kit is connected cannot be in the same group to which a City Multi indoor unit belongs.
2. A group operation using M-NET between the indoor unit to which the connection kit is connected and other indoor unit cannot be
performed properly if an M-NET Interface (MAC-333IF or MAC-399IF) is connected to the indoor unit using IT terminal.
3. If the connection kit is used, a group operation can be performed via the system controller or ME remote controller only. (A group
operation cannot be performed via the wireless remote controller or MA remote controller.)
