e.g. power cable with YJV cross-linked copper, insulated PE and PVC sheath) 
is lying on the surface of slot (IEC 60364-5-52). If working condition is changed, 
please adjust the specification according to national standard. 

(3)  Specification  of  circuit  breaker  is  based  on  the  working  condition  where 

ambient temperature of circuit breaker is 40

. If working condition is changed, 

please adjust the specification accordingly. 

(4)  Install cut-off device near the unit. The minimum distance between each stage 

of cut-off device should be 3mm. 

3.3   Wiring Work 

3.3.1 Requirements for Wiring Work 

(1)  The unit must be grounded securely, or it may cause electric shock. 
(2)  The capacity of power supply must be sufficient. The sectional area of wires  in 

the room should comply with relevant selection requirements and be installed 
with circuit breaker for branch circuit. 

(3)  The unit should be powered by independent circuit and specific socket. 
(4)  Install  circuit  breaker  for  branch  circuit  according  to  related  regulations  and 

electrical standards. 

(5)  All  wiring  must  use  pressure  terminal  or  single  wire.  Multi-twisted  wire  that 

connects directly to the wiring board may cause fire hazard. 

(6)  Keep cable away from fan and other motional parts. 
(7)  Do not alter the inner wires of unit. Manufacturer does not assume responsibility 

for damage or abnormal operation due to this reason. 

(8)  If  the  unit  is  installed  in  places  with  strong  electromagnetic  interference,  it's 

recommended to use twin-twisted shield wire. During wire connection, please 
pay  attention  that  the  metal  shield  layer  of  the  twin-twisted  wire  must  be 
grounded  (outer  case)  in  order  to  prevent  the  unit  from  electromagnetic 
interference. 

(9)  The communication wires should be separated from power cord and connection 

wire between indoor unit and outdoor unit. 

3.3.2 Connection of Wires and Wiring Board Terminals 

(1)  Connection of single branch wires 

1)  Use a stripper to strip away about 25mm of the insulation layer at the end of
