3.2.3 Side Cable Exit
If you adopt a side cable exit when you are installing the device, you need to reserve space for the side
cable exit and its slack. It is located on side plastic decoration plug. Use the correct tool to dig through the
U-shape slot to form a cable exit. Pull the cable through the hole.
In special circumstances, the installer may need the metal protection tube to protect themself when he pulls
through the cable from the side cable (PG11 screw thread port is provided). Please remove the plastic
decoration plug from the side panel of the chassis and pull through the cable to the tunnel of the PG11
screw thread. Now secure the tunnel in the PG11 screw threaded hole of the device.
