Safety Instructions
When working with CAN-CBX modules follow the instructions below and read the manual carefully
to protect yourself and the CAN-CBX module from damage.
Do not use damaged or defective cables to connect the CAN-CBX module 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-CBX module 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.
Do not open the housing of the CAN-CBX module.
The CAN-CBX module has to be securely installed before commissioning.
The permitted operating position is specified as shown (Fig. 9). Other operating positions are not
allowed.
Never let liquids get inside the CAN-CBX module. Otherwise, electric shocks or short circuits may
result.
Protect the CAN-CBX module from dust, moisture and steam.
Protect the CAN-CBX module from shocks and vibrations.
The CAN-CBX module may become warm during normal use. Always allow adequate ventilation
around the CAN-CBX module and use care when handling.
Do not operate the CAN-CBX module adjacent to heat sources and do not expose it to unnecessary
thermal radiation. Ensure an ambient temperature as specified in the technical data.
Qualified Personnel
This documentation is directed exclusively towards qualified personnel in control and automation
engineering.
The installation and commissioning of the product may only be carried out by qualified personnel,
which is authorized to put devices, systems and electric circuits into operation according to the
applicable national standards of safety engineering.
Conformity
The CAN-CBX module is an industrial product and meets the demands of the EU regulations and
EMC standards printed in the conformity declaration at the end of this manual.
Warning:
In a residential, commercial or light industrial environment the CBX-module may
cause radio interferences in which case the user may be required to take adequate
measures.
