In the case of the TN-C-S and TN-S AC power distribution systems, you are
advised to use the PE wire of the AC power cable for the ONU grounding
connection. The PE wire of the AC power cable for the corridor of the building is
already grounded properly.
–
Connect the ground bar and all the internal devices using the ground cable (the
cross-sectional area of the ground cable must be greater than or equal to 6 mm
2
),
and the ground bar to the network box in an equipotential manner through a
metallic structure.
–
Connect the grounding point of the strength member of the optical fiber to the
ground bar through a ground cable, or connect this grounding point to the network
box in an equipotential manner through a metallic structure.
–
When the PE line of the AC power cable in the corridor of the building does not
meet the grounding requirement, ground the network box through an external
ground cable (PGND cable) and ensure that the strength member of the optical fiber
is disconnected from the device ground point.

Guide for Grounding the Network Box of the TT Power Distribution System
–
In the case of the TT power distribution system, you are advised to use an external
ground device. For example, use a grounding device dedicated for buildings (such
as the ground flat steel, ground stud, and ground bar) or the base steel bar of the
reinforcement concrete of the building, or deploy a new ground grid.
–
Use the ground cable (the cross-sectional area of the ground cable must be greater
than or equal to 6 mm2) to connect the ground bar and all the internal devices, and
