Safety Instructions
● When working with the CAN-PN follow the instructions below and read the manual carefully to
protect yourself from injury and the CAN-PN from damage.
● Do not use damaged or defective cables to connect the CAN-PN 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-PN 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-PN.
● The CAN-PN has to be securely installed before commissioning.
● The permitted operating position is specified as shown (Figure: 14, page 33). Other operating
positions are not allowed.
●
Never let liquids get inside the CAN-PN. Otherwise, electric shocks or short circuits may result.
● Protect the CAN-PN from dust, moisture and steam.
● Protect the CAN-PN from shocks and vibrations.
● The CAN-PN may become warm during normal use. Always allow adequate ventilation around the
CAN-PN and use care when handling.
● Do not operate the CAN-PN adjacent to heat sources and do not expose it to unnecessary thermal
radiation. Ensure an ambient temperature as specified in the technical data.
