Remote Controllers - Mitsubishi Electric MVZ-A12AA7 Installation Manual

13.1. Remote controllers

Connecting remote controller, indoor and outdoor
transmission cables
Connect the "1" and "2" on the indoor unit TB15 to a remote
controller. (Non-polarized 2-wire)
Note:
Ensure that the wiring is not pinched when fitting the terminal box
cover. Pinching the wiring may cut it.
Caution:
Install wiring so that it is not tight and under tension. Wiring under
tension may break or overheat and burn.
Fix power source wiring to control box by using buffer bushing or
tensile force. (PG connection or the like.) Connect transmission
wiring to transmission terminal block through the knockout hole of
control box using ordinary bushing.
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 malfunction or fire.
After wiring is complete, make sure again that there is no tension
on the connections, and attach the cover onto the control box in the
reverse order removal. Also, seal any openings created from wiring
into the air handler. This will prevent air leakage.
Caution:
Wire the power supply so that no tension is imparted. Otherwise
disconnection, heating or fire may result.
Important:
Attach shielding ground on the outdoor unit's ground terminal.
If the remote controller cable exceeds 10 m [32 ft.], use a 1.25 mm
[AWG16] diameter cable over the exceeded portion, and add that
exceeded position to within 200 m [656 ft.].
