• Maximum wiring length: Within 200 m [656 ft]
• Maximum length of transmission lines for centralized control and indoor/outdoor transmission lines (Maximum length via outdoor units): 500 m [1,640 ft] MAX
The maximum length of the wiring between power supply unit for transmission lines (on the transmission lines for centralized control) and each outdoor unit and
system controller is 200 m [656 ft].

*1 A transmission booster (RP) may be required depending on the number of connected indoor unit controllers.
*2 OC, OS1 and OS2 of the outdoor units in the same refrigerant system are automatically identified. They are identified as OC, OS1 and OS2 in descending order of capacity.
(If the capacity is the same, they will be in ascending order of their address number.)
*3 When a PAR-30MAAU is connected to a group, no other MA remote controllers can be connected to the same group.

• When using wire size AWG 14, AWG 12, or AWG 10, be sure to use
knockout hole 2.
• When using wire size AWG 8 or AWG 6, be sure to use knockout hole 4.
• When using wire size AWG 4, AWG 3, or AWG 2, be sure to use knockout
hole 3.

• If there are any gaps around the wires, please be sure to fill these in with a
suitable material.
2 Conduit tube installation
• Open by hammering the knockout holes for the conduit tube located on the
base and the bottom part of the front panel.
• When installing the conduit tube directly through the knockout holes, remove
the burr and protect the tube with masking tape.
• Use the conduit tube to narrow down the opening if there is a possibility of
small animals entering the unit.
• When taking the conduit tube out from the bottom part of the unit, caulk
around the tube opening to prevent water penetration.
