equipment is not compromised.
Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven
mechanical loading.
Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of the circuit might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
Reliable Earthing: Reliable earthing of rack-mounting equipment should be maintained. Particular attention should be given to supply

INTRODUCTION
NOTE:
• Only use this instruction sheet to install your C3 Series Slide-Out Rack option after you refer to the C3
Series Credenza Frame instruction sheet (100-00032) and secure the frame to your wall.
• If your installation includes a purchased fan kit and/or a large cover option (for your purchased display
option), after installing this and any other options you may have purchased for your credenza, refer to
the C3 Series WoodKit instruction sheet (100-00040) to install your woodkit, and then refer to the C3
