4. Use the provided pan head screws to attach the rack ears on the I/O-facing posts to the long bracket previously attached to the
system. Tighten the pan head screws to secure the system.
Ground cable
To attach the ground cable to the chassis, use a single M4x0.7 screw.
The cable itself is not included with the S4810–ON. To properly ground the chassis, Dell Technology recommends using a 6AWG one-hole
lug, #10 hole size, 63" spacing (not in shipping). The one-hole lug must be a UL recognized, crimp-type lug.
NOTE:
The rack installation "ears" are not suitable for grounding.
CAUTION:
Grounding conductors
To connect the ground cable to the system, follow these steps.
NOTE:
Coat the one-hole lug with an antioxidant compound before crimping. Also, bring any unplated mating surfaces
to a shiny finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from
contamination.
1. Take one M4x0.7 screw from the package.
2. Cut the cable to the needed length. The cable length must facilitate proper operation of the fault interrupt circuits. Dell Technologies
recommends using the shortest cable route allowable.
3. Attach the one-hole lug to the chassis using the supplied 10 to 32 screw with the captive internal tooth lock washer. Torque the screw
to 20 in-lbs.
must be made of copper. Do not use aluminum conductors.
