ELECTRICAL WIRING
Wiring Connection (cont)
(1) Connection communication line:
Remove the cover of the electrical cabinet of the electronic expansion valve box. Introduce communication lines
for outdoor and indoor units to the through holes at the lower right of the electrical cabinet and crimp them on the
communication terminal block respectively. Then fix the lead wires with crimping pliers to prevent the communication
line from falling off under the effect of external force.
(2) Connection of power line and ground wire:
Remove the cover of the electrical cabinet of the connection kit. Introduce power lines to the through holes at the
lower left of the electrical cabinet and crimp them on power terminal block power. Then fix the power lines with
crimping pliers to prevent them from falling off under the effect of external force.
1) Do not route communication lines and power lines together. Otherwise, it may cause a malfunction or fault due to
electrical disturbance.
2) Make sure that ground wires are properly crimped. Otherwise, grounding may be ineffective.
