4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as the use of power strips).
Rack Mounting

(part #60-190-20) (see figure 1) or an RSU 129 standard Universal 1U Rack Shelf
(part #60-190-01) (see
