Electrostatic Discharge (ESD) Precautions

Modern integrated electronic devices, including the PowerStation, are extremely sensitive to electrostatic discharges (ESD) and fields. Before you open the system, be sure to follow these simple precautions to protect you and the PowerStation from harm resulting from ESD.

Once you have read and understood the ESD safety precautions, you are ready to continue with the appropriate instructions.

•Always disconnect power from the PowerStation before opening. Do not touch any internal components of the PowerStation while the system is on.

•Disconnect power before performing any internal maintenance or troubleshooting. A sudden static discharge as you connect a jumper or touch any internal parts may damage sensitive electronic components.

•Only handle internal components of the PowerStation in an ESD-safe location, using appropriate grounding methods.

•Wear a grounding wrist strap for continuous protection.

•Always ground yourself to remove any static charge before you touch the CPU card.

•Be particularly careful not to touch the components on the printed circuit boards.

•Keep any PowerStation part in its anti-static packaging when it is not installed in the unit and place it on a static dissipative mat when you are working on it.
