Rack Safety Instructions
v
Do not install this unit in a rack where the internal rack ambient temperatures will
exceed 40 degrees C.
v
Do not install this unit in a rack where the air flow is compromised. Any side, front or
back of the unit used for air flow through the unit must not be in direct contact with
the rack.
v
Care should be taken to ensure that a hazardous condition is not created due to
uneven mechanical loading when installing this unit in a rack. If the rack has a
stabilizer it must be firmly attached before installing or removing this unit.
v Consideration should be given to the connection of the equipment to the supply
circuit so that overloading of circuits does not compromise the supply wiring or
overcurrent protection. To provide the correct power connection to the rack, refer to
the rating labels located on the equipment in the rack to determine the total power
requirement for the supply circuit.
v An electrical outlet that is not correctly wired could place hazardous voltage on the
metal parts of the system or the devices that attach to the system. It is the
responsibility of the customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.
