8.3.3 Main Circuit Cables
Power cable selection requirements
For the selection of power cables, follow national or regional regulations. Select IEC
cables based on the following requirements:
● Compliant with IEC 60204‑1 and IEC 60364‑5‑52 standards
● PVC insulated cables with copper conductors
● Heat resistance: ambient temperature of 40°C and cable surface temperature of
70°C (Note: When the ambient temperature exceeds 40°C, contact Inovance.)
● Symmetrical cable with copper mesh shield
If specifications of recommended cables for peripheral devices or options are outside
the specification range of the cables applicable to the product, contact Inovance.
To meet the EMC requirements, the cable with the shield must be used. The shielded
cables are divided into three‑conductor cables and four‑conductor cables, as shown
below. If the conductivity of the three‑conductor cable shield cannot meet
requirements, add an independent PE cable. Alternatively, use a four‑conductor cable
with one conductor as the PE wire. The shield of the shielded cable is comprised of
coaxial cooper braids to suppress radio frequency interference. To enhance the
shielding performance and conductivity, the braided density of the shield must be
greater than 90%.
