ERGONOMIC FURNITURE
The new US furniture has two collection point ground lugs for in-station grounds (one for
chassis ground and one for MRG). There is also a ground lug for collecting the following:
• Logic Ground—in an HG on a Data Hiway that does not have an HTD (see Figures
4-2 and 4-3).
The HG terminal must be connected to the MRG ground stake with an insulated
5 m
2
(#4 AWG) wire.
• Third post (Safety Ground)—this post is connected to the station sheet metal and
can be wired to the safety ground in the power panel or to building steel with an
insulated 5 m
2
(#4 AWG) wire.
NOTE: The power cord has a safety ground connection. This second Safety
Ground connection is required by some codes.
