• The grounding conductor for the secondary side of the power transformer feeding the floor
• A grounding point specifically provided in the building for that purpose
Warning:
If the approved ground or approved floor ground can only be accessed inside a dedicated power
equipment room, then connections to the ground must be made by a licensed electrician.
ANSI/EIA/TIA-607:
In buildings where a ground-cabling infrastructure meeting TIA-607 has been implemented the
Avaya equipment shall be grounded according to the TIA-607 standard. In a TIA-607 installation, the
Telecommunications Main Grounding Busbar (TMGB)/Telecommunications Grounding Busbar
(TGB) links the telecommunications equipment to the ground.
Other grounding terminology is:
• Building principle ground, normally in a building with one floor.
• Floor ground bar, normally in buildings with more than one floor.
Refer to
Figure 7: ANSI/TIA/EIA-607 Grounding Schematic on page 38.
Configure telecommunications subsystems, such as groups of frames or equipment, as separate
single-point ground entities connected to the equipment’s dedicated service panel via a single-point
ground bar. The service panel ground connects to the building principle ground via the main service
panel or, in a TIA-607 installation, via the TGB. Refer to
Figure 8: Typical Wiring Plan on page 39.
