Safety Instructions
When working with CAN-CBM-Clock module follow the instructions below and read the
manual carefully to protect yourself and the CAN-CBM-Clock module from damage.
The permitted operating position is specified as shown (Fig. 7). Other operating positions are
not allowed.
Do not use damaged or defective cables to connect the CAN-CBM-Clock 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 objects.
Current circuits which are connected to the device have to be sufficiently protected against
hazardous voltage (SELV according to EN 60950-1).
The CAN-CBM-Clock 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 or PELV)
according to EN 60950-1, complies with this conditions.
Do not open the housing of the CAN-CBM-Clock module.
The CAN-CBM-Clock module has to be securely installed before commissioning.
Never let liquids get inside the CAN-CBM-Clock module. Otherwise, electric shocks or short
circuits may result.
Protect the CAN-CBM-Clock module from dust, moisture and steam.
Protect the CAN-CBM-Clock module from shocks and vibrations.
The CAN-CBM-Clock module may become warm during normal use. Always allow adequate
ventilation around the CAN-CBM-Clock module and use care when handling.
Do not operate the CAN-CBM-Clock module 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-
CBM-Clock is to be integrated.
Qualified Personal
This documentation is directed exclusively towards qualified personal 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.
Intended Use
The intended use of the CAN-CBM-Clock module is the operation as a real time clock with CAN
interface. The esd guarantee does not cover damages which result from improper use, usage not in
accordance with regulations or disregard of safety instructions and warnings.
