To prevent poor cable connection due to overstress caused by ground subsidence, you are
advised to bend the cable inside the cabinet for a slack of 20–30 mm (0.79–1.18 in.) before
connecting the cable to the appropriate port.
If a cable has a jacket, ensure that the jacket is in the cabinet.
This section describes how to connect a peripheral cable to the RS485/ETH/DC
waterproof connector in common mode and through a tube, and provides a reference for
connecting peripheral cables to other waterproof connectors.
5.1.1 Common Connection
If you choose common connection, ensure that an appropriate cable is available.
Step 1
Remove the locking cap and plug from the waterproof connector.
Step 2
Route the cable through the locking cap and then the waterproof connector.

Routing a cable
Step 3
Connect the cable and tighten the locking cap.
Step 4
Check that the cable is connected correctly and securely. Seal the waterproof connector and
cable hole using the supplied firestop putty.
Step 5
Clear foreign matter from the cabinet.

5.1.2 Connection Through a Tube
If you choose connection through a tube, ensure that an appropriate cable and a tube are
available.
Prepare an appropriate tube based on the diameter of the cable holes at the bottom. It is
recommended that the tube specifications comply with the waterproof connector specifications. For
example, for a 3/4 in. waterproof connector, a 3/4 in. tube is recommended.
The tube appearance is for reference only. The actual tube prevails. This is applicable to all other
similar figures.
