6Connecting Cables
Connect cables in accordance with the installation laws and regulations of the country or region
where the project is located.
NOTICE

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
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.
If you choose common connection, ensure
that the appropriate cable is available.
16
NOTE
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.

NOTE
Selecting a Connection Method
6.1
You can connect a peripheral cable to the smart array controller in common mode or through a
tube based on site requirements.

17
1. Remove the locking cap and plug from the
waterproof connector, and then remove the
waterproof connector.
2. Secure the tube fitting using the nut
delivered with the tube.
3. Route the cable through the tube conduit
and then fitting.
4. Connect the cable.
5. Secure the fitting to the conduit.
6. Check that the cable is connected correctly
and securely. Then take appropriate
measures to ensure that the tube conduit
and fitting are secured reliably, and seal the
cable hole using supplied firestop putty.
7. Clear foreign matter from the cabinet.
You can connect a peripheral cable to the smart array controller in common mode or through a tube.
The way of handling the bottom waterproof connector varies depending on the connection
method. For details, see section 6.1 "Selecting a Connection Method."
Cables to the cabinet interior are connected in the same way irrespective of which connection
method is used. The following uses common connection as an example.
Preparing Cables
6.2
Before connecting cables, prepare appropriate cables by referring to chapter 2 "Configurations in
Typical Scenarios."

Crimping an OT Terminal
6.3
Avoid scratching the core
wire when stripping a cable.
The cavity formed after the
conductor crimp strip of the
OT terminal is crimped must
wrap the core wires
completely. The core wires
must contact the OT
terminal closely.
Wrap the wire crimping area
with heat shrink tubing or
PVC insulation tape. The
right figure uses heat shrink
tubing as an example.
When using the heat gun,
protect devices from being
scorched.

Connecting the PE Cable
6.4
1. Crimp an OT terminal.
2. Secure the PE cable.
Connect the PE cable to the nearest
ground point or the ground bar in the box-
type transformer.
To enhance the corrosion resistance of a
ground terminal, you are advised to apply
silica gel or paint on it after connecting the
ground cable.
Connecting Communications Cables for the Fiber Ring Network
6.5
Prepare the fitting bag for optical ring
switching which contains the low-speed
optical module and optical jumper.
1. Insert the low-speed optical modules
respectively into the SFP1 and SFP2
ports of the SmartLogger until they snap
into place. Then pull the modules back to
ensure that they are connected securely.
