Figure 5-9
Checking connectivity
The connectivity meets standards if the following conditions are met:
Positive and negative holes of the connector are not short-circuited.
The metal enclosure and connector's holes are not short-circuited.
The cable shield layer is properly connected to the metal enclosure.
Core wires are properly connected to the connector's holes.
Step 9
If devices are installed outdoor, wrap three layers of PVC insulation tape around the
connector for protection, as shown in Figure 5-10.
Ensure that proper quantity of the PVC insulation tape is used for wrapping the connector,
facilitating the connector uninstallation in later maintenance.
