Safety Instructions

● When working with the CPCI-CAN/331 follow the instructions below and read the manual 

carefully to protect yourself from injury and the CPCI-CAN/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 CPCI-CAN/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 CPCI-CAN/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 CPCI-CAN/331 from dust, moisture and steam. 
● Protect the CPCI-CAN/331 from shocks and vibrations.
● The CPCI-CAN/331 may become warm during normal use. Always allow adequate ventilation 

around the CPCI-CAN/331 and use care when handling.

● Do not operate the CPCI-CAN/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 CPCI-
CAN/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  CPCI-

CAN/331, in order to discharge the static electricity from your body.

Qualified Personal

This documentation is directed exclusively towards  personal qualified in control and automation
engineering. 
The installation and commissioning of the product may only be carried out by qualified personal,
which is authorized to put devices, systems and electric circuits into operation according to the
applicable national standards of safety engineering.

Conformity

The CPCI-CAN/331-2 meets the demands of the EU regulations and EMC standards printed in the
conformity declaration at the end of this manual.
