Safety Instructions
● When working with the CAN-PC104/331 follow the instructions below and read the manual
carefully to protect yourself from injury and the CAN-PC104/331 from damage.
● The device is a built-in component. It is essential to ensure that the device is mounted in a way
that cannot lead to endangering or injury of persons or damage to objects.
● Do not use damaged or defective cables to connect the CAN-PC104/331 and follow the CAN
wiring hints in chapter: "Correct Wiring of Electrically Isolated CAN Networks".
● In case of damages to the device, which might affect safety, appropriate and immediate
measures must be taken, that exclude an endangerment of persons and domestic animals and
property.
● Current circuits which are connected to the device have to be sufficiently protected against
hazardous voltage (SELV according to EN 60950-1).
● The CAN-PC104/331 may only be driven by power supply current circuits, that are contact
protected. A power supply, that provides a safety extra-low voltage (SELV) according to
EN 60950-1, complies with this conditions.
● The device has to be securely installed in the control cabinet before commissioning.
● Protect the CAN-PC104/331 from dust, moisture and steam.
● Protect the CAN-PC104/331 from shocks and vibrations.
● The CAN-PC104/331 may become warm during normal use. Always allow adequate ventilation
around the CAN-PC104/331 and use care when handling.
● Do not operate the CAN-PC104/331 adjacent to heat sources and do not expose it to
unnecessary thermal radiation. Ensure an ambient temperature as specified in the technical
data.
DANGER
Hazardous Voltage -
Risk of electric shock
due to unintentional contact with
uninsulated live parts with high voltages inside of the system into which the CAN-
PC104/331 is to be integrated.
→ Disconnect all hazardous voltages (mains voltage) before opening the system.
→ Ensure the absence of voltage before starting any electrical work
NOTICE
Electrostatic discharges may cause damage to electronic components.
To avoid this, perform the steps described on page 11
before
you touch the CAN-
PC104/331, in order to discharge the static electricity from your body.
