Locating and Grounding the CPT 50 Shelf

Before locating and grounding the CPT 50 shelf, you must complete the prerequisites mentioned in
"Prerequisites" section on page
shelf:
Verify that the office ground cable is connected to the top of the bay and the office ground, according to
Step 1
local site practice. (See
The CPT 50 installations are suitable for Network Telecommunication facilities and locations where
Note
NEC applies.
Note Additional ground cables may be added depending on local site practice. The CPT 50 shelf is designated
only for a Common Bonding Network (CBN), according to the GR-1089-CORE Issue 5 (sec 9.3)
definitions.
Note The DC power battery return (BR) terminal or positive terminal must be grounded at the source end
(power feed or DC mains power end). The DC power BR input terminal is not connected to the
equipment frame (chassis), so it is configured as DC-1 according to the GR-1089-CORE, Issue 5
(sec 9.8.3) definitions.
