4.4. Wiring dimensions

Table 4.4 shows all the information needed to calculate the necessary number of cables and their sizes. This specific section is a
guide, since the wiring must be calculated according to the electrical code of the region where the equipment is installed.
Remember that the various signals do not interfere with each other, so all the cables can be placed together, even inside the same
cable hose.
