Consideration should be given to the connection of the equipment to the supply
circuit, so that overloading of circuits does not compromise the rack supply wiring
or over-current protection. To provide the correct power connection to the rack,
refer to the rating labels located on the equipment installed the rack to determine
the total power requirement for the supply circuit.
Do not install this unit in a rack where the internal rack ambient temperatures will
exceed 40 degrees Celsius.
Do not install this unit in a rack where the air flow is compromised.
To ensure proper cooling, place the unit so that the cooling fan exits at the rear of
the unit and the air inlet holes at the front of the unit have sufficient clearance to
ensure airflow.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the products that attach to the system. It is the
customer’s responsibility to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock. (RSFTD201)
