4 Safety
The following chapter provides safety and regulatory information for the 4U60 Storage Enclosure.
4.1 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 elds, excessive dust, and electronic/electrical equipment that generate
electrical noise.
4.2 Safety Warnings and Cautions
To avoid personal injury or property damage, before you begin installing the product, read, observe, and adhere to all of
the following safety instructions and information. The following safety symbols may be used throughout the documentation
and may be marked on the product and/or the product packaging.
CAUTION Indicates the presence of a hazard that may cause minor personal injury or property damage if the CAUTION
is ignored.
WARNING Indicates the presence of a hazard that may result in serious personal injury if the WARNING is ignored.
Indicates potential hazard if indicated information is ignored.
Indicates shock hazards that result in serious injury or death if safety instructions are not followed.
Indicates do not touch fan blades, may result in injury.
Indicates disconnect all power sources before servicing.
4.3 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.
11
Installation Guide 4 Safety

Before moving ESD-sensitive parts place them in ESD static-protective bags until you are ready to install the part.
4.4 Rackmountable Systems
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) specied by the manufacturer.
Observe the maximum rated ambient temperature, which is specied 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
ow 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, unmodied 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.
CAUTION To avoid electrical shock or re, check the power cord(s) that will be used with the product as follows:
• The power cord must have an electrical rating that is greater than that of the electrical current rating marked on the
product.
• Do not attempt to modify or use the AC power cord(s) if they are not the exact type required to t into the grounded
electrical outlets.
• The power supply cord(s) must be plugged into socket-outlet(s) that is /are provided with a suitable earth ground.
• The power supply cord(s) is / are the main disconnect device to AC power. The socket outlet(s) must be near the
equipment and readily accessible for disconnection.
12
Installation Guide 4 Safety

4.7 Safety and Service
All maintenance and service actions appropriate to the end-users are described in the product documentation. All
other servicing should be referred to a HGST-authorized service technician.
To avoid shock hazard, turn off power to the unit by unplugging both power cords before servicing the
unit. Use extreme caution around the chassis because potentially harmful voltages are present.
When replacing a hot-plug power supply, unplug the power cord to the power supply being replaced before
removing it from the 4U60 Storage Enclosure.
The power supply in this product contains no user-serviceable parts. Do not open the power supply. Hazardous
voltage, current and energy levels are present inside the power supply. Return to manufacturer for servicing.
Use caution when accessing part of the product that are labeled as potential shock hazards,
hazardous access to moving parts such as fan blades or caution labels.
