Rack mount safety considerations

• Elevated Operating Ambient Temperature: If the PM PDU is installed in a closed or multi-unit

rack assembly, the operating ambient temperature of the rack environment may be greater than

room ambient temperature. Therefore, consideration should be given to installing the

equipment in an environment compatible with the manufacturer’s maximum rated ambient

temperature.

• Reduced Air Flow: Installation of the equipment in a rack should be s

ch that the amount of air

flow required for safe operation of the equipment is not compromised.

• Mechanical Loading: Mounting of the equipment in

the rack should be such that a hazardous

condition is not created 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 circuits might have on overcurrent protection

and supply wiring. Appropriate consideration of equipment nameplate ratings should be used

when addressing this concern.

• Reliable Grounding: Reliable grounding of rack mounted equipment should be maintained.

Particu

ar attention should be given to supply connections other than direct connections to the

branch circuit, such as power strips or extension cords.

NOTE: Install a PM PDU model in a location where there is an adjacent and accessible socket outlet.

Safety Precautions

Read all the following safety guidelines to protect yourself and your PDU.

WARNING: All outlets of the PDU output high voltage. Necessary precautions should be taken.
