 Installing system grounds

Communication Server 1000E

Installation and Configuration

Connect the NTDU6201 Ground Bar to the ground bus in the AC electrical 
panel, or to TGB for an ANSI/EIA/TIA 607 installation using #6 AWG wire. 
See Table 12 on 

 for region-specific grounding requirements. 

Place a tag marked DO NOT DISCONNECT on the ground wire at the 
electrical panel.

Test the ground.

The CS 1000E Call Servers are not connected to a ground bar. They are 
properly grounded when: 

•

the CS 1000E power cord is plugged into the rack’s AC outlet. The 
rack’s AC outlet must be grounded to its dedicated electrical panel. This 
is the preferred method. 

•

the CS 1000E power cord is plugged into a wall AC outlet. The 
CS 1000E is grounded outside of the rack using the safety grounding 
conductor in the power cord. This method ensures proper grounding only 
of the CS 1000E itself. It does not provide grounding protection for other 
rack-mounted pieces of equipment. Therefore, ensure that other devices 
in the rack are properly grounded as required. 

The Signaling Server is not connected to a ground bar. It is properly grounded 
when: 

•

the Signaling Server power cord is plugged into the rack’s AC outlet. The 
rack’s AC outlet must be grounded to its dedicated electrical panel. This 
is the preferred method. 

A qualified technician or electrician must make the 
connection in the AC electrical panel.
