Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment and impair
electrical circuitry. It occurs when electronic components are improperly handled and can result in complete
or intermittent failures.
Wear an ESD wrist strap for installation, service and maintenance to prevent damage to components in the
product. Ensure the antistatic wrist strap is attached to a chassis ground (any unpainted metal surface). If
possible, keep one hand on the frame when you install or remove an ESD-sensitive part.
Before moving ESD-sensitive parts place them in ESD static-protective bags until you are ready to install the
part.

CAUTION
Always install rack rails and storage enclosure according to 4U60 Storage Enclosure product
documentation. Follow all cautions, warnings, labels, and instructions provided within the rackmount
instructions.
Reliable earthing of rack-mounted equipment should be maintained.
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Observe the maximum rated ambient temperature, which is specified in the product documentation.
For safe operation of the equipment, installation of the equipment in a rack should be such that the
amount of air flow is not impeded so that the safe operation of the equipment is not compromised.
4.5
Power Connections
Be aware of the ampere limit on any power supply or extension cables being used. The total ampere rating
being pulled on a circuit by all devices combined should not exceed 80% of the maximum limit for the circuit.
CAUTION
The power outlet must be easily accessible close to the unit.
Always use properly grounded, unmodified electrical outlets and cables. Ensure all outlets and
cables are rated to supply the proper voltage and current.
This unit has more than one power supply connection; both power cords must be removed from the
power supplies to completely remove power from the unit. There is no switch or other disconnect device.
4.6
Power Cords
Use only tested and approved power cords to connect to properly grounded power outlets or insulated
sockets of the rack's internal power supply.
If an AC power cord was not provided with your product, purchase one that is approved for use in your country
or region.
