6 Safety
The following chapter provides safety and regulatory information for the Ultrastar Data60.
6.1 Electrostatic Discharge
CAUTION
Electrostatic discharge can harm delicate components inside HGST products.
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.
6.2 Optimizing Location
Failure to recognize the importance of optimally locating your product and failure to protect against electrostatic
discharge (ESD) when handling your product can result in lowered system performance or system failure.
Do not position the unit in an environment that has extreme high temperatures or extreme low temperatures.
Be aware of the proximity of the unit to heaters, radiators, and air conditioners.
Position the unit so that there is adequate space around it for proper cooling and ventilation. Consult the
product documentation for spacing information.
Keep the unit away from direct strong magnetic fields, excessive dust, and electronic/electrical equipment
that generate electrical noise.
6.3 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.
