5.3 Power Supply (P4A, P4B, UEGM)
NOTICE
The CAN-Repeater must not be connected to a DC power supply without protection
against surge voltages.
→
→
Use an external overvoltage protection!
All current circuits which are connected to the CAN-Repeater have to be sufficiently
protected against hazardous voltage (SELV according to EN 60950-1) before you
start with the installation.
Power is supplied by means of UEGM connectors integrated in the housing. The connectors are
suitable for lines with a cross section of up to 2.5 mm².
The connectors have been assigned in the same way on both sides of the housing. They can be
used alternatively. The middle contact has been designed for +24 V and the two outer contacts for
GND.
NOTICE
It is
not permissible
to feed through the supply voltage, i.e. to use one side as a 24 V
input and the other side as a 24 V output in order to supply further devices, for instance!
