Attach a Grounding Cable for TT Power Systems
 | Caution - When installing the rack in Japan, or other locations that use a TT power systems, you must attach a separate grounding cable to the rack. |
-
Obtain a grounding cable that is at least 6 AWG in size.
A grounding cable is not shipped with the rack. The minimum supported AWG size is 6.
-
Attach the grounding cable to the rack grounding terminal using a
crimped-on lug suitable to secure the grounding cable to the grounding
terminal.
The rack has a metric M8 stud for its grounding terminal. Securely tighten the crimped-on lug down on the grounding terminal using a lockwasher and nut. The grounding connection must be securely made with clean metal to metal contact.
-
Attach the other end of the grounding cable to a reliable earthing point
in the building using established electrical guidelines and in accordance
with electrical codes for the country of installation.
Caution - If the installed equipment makes additional connections to earth ground, ensure that all grounding points reference the same earth ground to prevent dangerous ground loops.
