The sizing of the power cable depends on various factors:
• Module size (8 or 10 outputs)
• Environment temperature
• Type of cable used
• How to lay the cable
It is necessary to guarantee the protection against short circuit and overload of the cable, respecting the pre-
scriptions contained in the IEC 60204-1 standard. In case the apparatus must equip machinery that must meet
different standards, refer to them for more details.
The following table summarizes the minimum sections required for the power supply cable, using cables with
PVC insulation of 70 ° C, or XLPE / EPR from 90 ° C, assuming that the above protection devices are used
upstream of them. This table presupposes a laying of the cable in free air (similar to the installation category E
of IEC 60364-5-52).
If you intend to use cables of different types, or the way of laying cables is different from the one illustrated
above, please refer to the IEC 60364-5-52 standard for more information on the criteria for dimensioning them.
Do not install the device where the expected short-circuit current exceeds 5 kA. Danger of
fire and damage to people and property.
The use of an inadequate overcurrent protection device could cause it to fail to intervene,
with danger for people and things. Additionally, spurious protection interventions may occur.
