Cable Path Inspection
When installing a cable that connects between the rectifier, Main Ground Bar (MGB), and
backhaul device, etc. within the system, the cable path length and the cable installation
method, etc. must be inspected.
Follow these guidelines when inspecting the cabling path.

A minimum cable length must be selected provided that it does not affect the cable
installation and maintenance.

The cable must be placed in a location where it will not be damaged by external
factors. (power line, flooding, footpaths, etc.)

In areas where the cable may be damaged by external factors, ensure that measures are
taken to prevent damage to the cable. (cable tray, ducts, flexible pipe, etc.)
Cable Cutting
Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool.
Follow these guidelines when cutting the cable.

Cut the cable to the length determined in the Cable Path Inspection step.

Use a dedicated cable cutting tool.

Cut the cable at right angles.

Be careful to keep the cable away from any moisture, iron, lead, dust or other foreign
material when cutting. Remove any foreign material attached to the cable using
solvent and a brush.
Cable Installation
Cable installation involves running the cable along the cabling path to the target connector
of the system or an auxiliary device after cable path inspection and cable cutting have been
completed.
Follow these guidelines when installing a cable.

Be careful not to damage the cable.

If the cable is damaged, cut out the damaged section before installing.

When installing the cable over other cables, make sure the cable is installed on the
other cables. Pay more attention to the vertical and horizontal cross sections where the
cables are usually reversed.

Always use the maximum curvature radius possible, and make sure that the minimum
curvature radius specification is complied with.

If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible pipe, and
cable rack, etc.
