2.4 Safety Instructions to avoid Personal Injury
To ensure your own personal safety and to avoid personal injury, you
necessarily must read, understand and follow the following safety
instructions and safety messages in this manual about danger causing
personal injury, before you install and operate your PC card cifX.
2.4.1
Electrical Shock Hazard
The danger of a lethal electrical shock caused by parts with more than 50V
may occur if you open the PC cabinet to install the PC card cifX.
HAZARDOUS VOLTAGE is present inside of the PC or of the connec-
ting device, into which the PC card cifX is integrated. Strictly obey to all
safety rules provided by the device’s manufacturer in the documentation!
First disconnect the power plug of the PC or of the connecting device,
before you open the cabinet.
Make sure, that the power supply is off at the PC or at the connecting
device.
Open the PC cabinet and install or remove the PC card cifX only after
disconnecting power.
An electrical shock is the result of a current flowing through the human
body. The resulting effect depends on the intensity and duration of the
current and on its path through the body. Currents in the range of
approximately ½ mA can cause effects in persons with good health, and
indirectly cause injuries resulting from startle responses. Higher currents
can cause more direct effects, such as burns, muscle spasms, or
ventricular fibrillation.
In dry conditions permanent voltages up to approximately 42.4 V peak or
60 V DC are not considered as dangerous if the contact area is equivalent
to the size of a human hand.
