Note:
①
Specification of circuit breaker and power cord is selected on the basis of unit’s maximum
power (max. current).
②
Specification of power cord is based on the working condition where ambient temperature is
40 and multi-core cable with copper conductor(working temperature is 90 , e.g. power cable with
YJV cross-linked copper, insulated PE and PVC sheath) is lying on the surface of slot. If working
