11. Electrical connection
11.1Electrical connection precaution
Warning
Installation of electric items must be carried out by
qualified, professional technicians. An isolated
circuitry should be fixed with whole-pole
disconnection devices, which is with at least 3mm
gap of touch point. . Power supply and indoor to
outdoor connection should use special cable.
Providing the necessity of installation or
replacement, the professional technician of service
store appointed by manufacturer must be required,
while self-operation by users is prohibited.
In case of any electric shock accident, the creepage
protection devices /power supply on-off and breaker
must be required with power supply.
The specification of fuse for single phase control board is F5AL 250V, while for 3 phase control
board, both indoor and outdoor unit, it is F3.15AL 250V
。
Machine must be earthed surely. If not, it’ll be probably caused creepage.
Equivalent 227IEC53(RVV) type of power cord of GB5023 or the excelled must be required. The
cords should be fixed properly against broken, while ends/joints of cords is under outside force.
Improper connection or fixation will cause disaster like fire….etc. Equivalent 245IEC57(YZW) type
of power cord of GB5023 or the excelled must be used as connection line of indoor and outdoor.
Notice
The earth line is neither allowed to connect to gas pipe, water pipe or circuitry of telephone or
lighting rod, nor to the earth line of other devices.
Others
Please fix power supply cord and connection wires of indoor and outdoor, in accordance with
circuit diagram
Fix the cords into terminal boards properly and safely with cable fixation tools to avoid any danger
caused by the power cord under outside forces.
After fixation, use bind tape (affixed) to bind wires avoiding any collision with other components like
compressor, copper pipes…etc
