Site Preparation
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 over-current protection and supply wiring.
When connecting equipment to a supply circuit, proper consideration should be taken to avoid
overloading the supply circuits.
Reliable Earthing
•
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 (e.g., use of power
strips).
Rack Allocation
Allow 14 RUs for the Selenio VMG AC system.
•
Allow 13 RUs for the Selenio VMG DC system.
•
Power Connectivity
