12. ELECTRICAL WORK
AIR TO WATER
12-4. Connecting remote controller, indoor and outdoor transmission cables
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 controller.
Power supply examples
Using MA Remote controller (Remote controller is optionally available)
Connect the "1" and "2" on unit TB15 to a MA remote controller. (Non-polarized 2-wire)
DC 10 to 13 V between 1 and 2 (MA remote controller)
The MA remote controller cannot be used at the same time or interchangeably.
Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the wiring may cut it.
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 supplemental insulation.
Use a single multiple-core cable for external input/output to allow for connection to the PG screw.
Wire the power supply so that no tension is imparted. Otherwise disconnection, heating or fire result.
