6.1 Selecting a Connection Method
You can connect a peripheral cable to the smart array controller in common mode or through a
tube based on site requirements.
To prevent poor cable connection due to overstress caused by ground subsidence, it is

recommended that the cable be bent and reserved 20–30 mm (0.79–1.18 in.) inside the cabinet
and then connected to the appropriate port.
If a cable has a jacket, ensure that the jacket is in the cabinet.

 The following describes how to connect a peripheral cable to the RS485/ETH/DC waterproof
connector in common mode and through a tube, and provides reference for connecting
peripheral cables to other waterproof connectors.
Common Connection
If you choose common connection, ensure
that the appropriate cable is available.
1. Remove the locking cap and plug from
the waterproof connector.
2. Route the cable through the locking
cap and then the waterproof connector.
3. Connect the cable.
4. Tighten the locking cap.
5. Check that the cable is connected
correctly and securely. Seal the
waterproof connector and cable hole
using the supplied firestop putty.
6. Clear foreign matter from the cabinet.
Connection Through a Tube
If you choose connection through a tube, ensure that the appropriate cable and tube are available.
Prepare appropriate tubes based on the diameters of bottom cable holes. 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.
