Power cable selection requirements
For the selection of power cables, follow national or regional regulations. Selection of
IEC cables is based on the following:
●
EN 60204‑1 and IEC 60364‑5‑52 standards
●
PVC cable with copper conductors
●
Working properly when the ambient temperature is equal to or lower than 40℃
and the cable surface temperature is equal to or lower than 70℃ (Note: Contact
the manufacturer if the ambient temperature exceeds 40°C.)
●
Symmetrical cable with copper mesh shield
If the recommended cables for peripheral equipment or options are not suitable for
the product, contact Inovance.
To comply with the EMC standards, use shielded cables. The shielded cables are
divided into three‑conductor cables and four‑conductor cables, as shown below. If
the conductivity of three‑conductor cable shield cannot meet requirements, add an
independent PE cable or use a four‑conductor cable with one conductor as the PE. To
suppress radio frequency interference effectively, use the coaxial copper braid as the
cable shield. Ensure that the braided density is greater than 90% to enhance the
shielding performance and conductivity.
