About the electrical wiring

It is important to keep the power supply and the transmission wiring
separated from each other. In order to avoid any electrical
interference the distance between both wiring should always be at
least 1 inch.
NOTE
▪ Be sure to keep the power line and transmission line
apart from each other. Transmission wiring and power
supply wiring may cross, but may not run parallel.
▪ Transmission wiring and power supply wiring may not
touch internal piping (except the inverter PCB cooling
pipe) in order to avoid wire damage due to high
temperature piping.
▪ Firmly close the lid and arrange the electrical wires so
as to prevent the lid or other parts from coming loose.
The transmission wiring outside the unit should be routed in conduit.
Be sure to follow the limits below. If the unit-to-unit cables are
beyond these limits, it may result in malfunction of transmission:

For the above wiring, always use vinyl cords with AWG18 to AWG16
sheath or cables (2-core wires). 3-core wire cables are only
allowable for the cooler/heater changeover user interface.
