Caution:
Do not use anything other than the correct capacity breaker and fuse. Using
fuse, wire or copper wire with too large capacity may cause a risk of malfunc-
tion or fire.
10.2. Connecting remote controller, indoor
and outdoor transmission cables
(Remote controller is optionally available.)
• Connect unit TB5 and outdoor unit TB3. (Non-polarized 2-wire (shield))
The "S" on unit TB5 is a shielding wire connection. For specifications about the
connecting cables, refer to the outdoor unit installation manual.
• Install a remote controller following the manual supplied with the remote control-
ler.
• Connect the "1" and "2" on unit TB15 to a MA remote controller. (Non-polarized
2-wire)
[Fig. 10.2.1] (P.6) MA Remote controller
• DC 10 to 13 V between 1 and 2 (MA remote controller)
[Fig. 10.2.2] (P.6) MA Remote controller
• The MA remote controller cannot be used at the same time or interchangeably.

Note:
Ensure that the wiring is not pinched when fitting the terminal box cover.
Pinching the wiring may cut it.
Caution:
• Use wire with supplemental insulation.
• Input to TB142A, TB142B, and TB142C should not carry voltage.
• Cables from equipment connected to external input/output should have supple-
mental insulation.
• Use a single multiple-core cable for external input/output to allow for connection to
the PG screw.
Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnec-
tion, heating or fire result.

10.3. External input/output function

Preset temperature input (external analog input: 4mA-20mA)
External input is input through CN421, CN422 on the circuit board. (Fig. 10.3.1)
Use the supplied connector.
If no temperature settings are made via the MA remote controller, the temperature
changes with the current.
Refer to the instructions manual that came with the MA remote controller for how to
make the settings.
4 mA → 10 °C 20 mA → 70 °C
Note:
Use a 4-20 mA signal output device with insulation.

External output terminal
External output terminal (refer to Fig. 10.3.2) is ineffective when the circuit is open.
Refer to Table 10.3.2 for information about each contact.
The current and voltage in the circuit to be connected to external output terminal
(TB141A OUT1) must meet the following conditions.
Contact rating
current
AC250V 1A or less
AC125V 3A or less

External input terminal
The wire length must be within 100 m.
External input terminal (refer to Fig. 10.3.3) is ineffective when the circuit is open.
Refer to Table 10.3.3 through Table 10.3.5 for information about each contact.
Only the "pump interlock" function is ineffective when the circuit is short-circuited.
Connect a relay circuit to the external output terminal as shown in Fig. 7.4.1.
The specifications of the relay circuit to be connected must meet the following condi-
tions.
Contact rating voltage DC15V
Contact rating current 0.1A
Minimum applicable load 1mA at DC
