▪ Insert 10~15 cm of the power supply cable, the RS485 cable, and
the P1P2 cable together through a heat shrink tube (field supplied)
and use a heat gun to shrink the tube. Leave enough free room at
the end of the cables so they can still be connected easily to the
PCB once inside the installation box.
▪ With the cable gland oriented on top of the box, insert the power
supply cable, the RS485 cable, and the P1P2 cable through the
right cable gland, from the outside of the box to the inside. Inside
the box, the cables must split again into three separate cables so
they can reach their respective terminals without any strain, as
shown on the following figure.
▪ Connect the wiring to the PCB. For more information, also see "5.4
