Connecting Cables

Connect cables in accordance with the installation laws and regulations of the country or region
where the project is located.
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 inside the cabinet for a slack of 20–30 mm (0.79–1.18 in.)
before 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 an appropriate cable is available.
1. Remove the locking cap and plug from
the cable gland.
2. Route the cable through the locking cap
and then the cable gland.
3. Connect the cable.
4. Tighten the locking cap.
5. Check that the cable is connected
correctly and securely. Seal the cable
gland 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 an appropriate cable and a tube are available.
Prepare an appropriate tube based on the diameters 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.
