POWER AND GROUNDING OF ALL RACKS

When using PDUs, each PDU should be connected to a committed 

branch circuit that is rated for the continuous load of all the equipment 

connected.  When not using a PDU, each piece of equipment should be 

connected to a dedicated branch circuit.

PROTECTIVE EARTHING/GROUNDING

A main protective earthing lug is provided.

 

  

WARNING: 

To avoid injury to persons or loss of life, 

              ground rack individually to the dedicated branch circuit      

earthing ground.

CONNECTING MAIN PROTECTIVE EARTHING LUG TO THE 

DEDICATED BRANCH CIRCUIT EARTHING GROUND CONDUCTOR

Connect the dedicated branch circuit earthing ground conductor to 

the main protective earthing stud located on the support frame using a 

listed ring or closed-loop terminal.
Although equipment may physically fit into a Great Lakes rack, with 

or without brackets, customers must also review and comply with the 

equipment manufacturer’s installation and other requirements.  For 

more information, please contact your Great Lakes representative or 

call 1.866.879.4522
