When installation environment (such as routing mode and ambient temperature) changes,
prepare cables based on specifications in IEC60364-5-52 or local standards.
When the mains input and bypass input share a power source, configure mains input
power cables as input power cables. The cables listed in
the following requirements are met:
−
The cables are installed along the wall or on the floor (IEC60364-5-52 C standards).
−
The ambient temperature is 30°C.
−
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%. The
recommended cross-sectional areas in
meet the basic through-current
requirements. Users should evaluate the line voltage loss based on the actual cable
length. If the voltage loss exceeds the requirements, increase the cable
cross-sectional areas properly.
−
90°C copper-core cables are used.
When selecting, connecting, and routing power cables, follow local safety regulations
and rules.
