3.1
VersaPoint potential and data routing
For operation, the safety module must be integrated in an VersaPoint station within the
VersaSafe system.
The bus signals are transmitted via the VersaPoint data jumpers. The required supply volt-
ages are transmitted via the VersaPoint potential jumpers.
Important
For more detailed information on potential and data routing within an VersaPoint station,
please refer to the GFK-2736 user manual.
The segment circuit is looped through the safety module and is available again after the
module. The segment circuit cannot be accessed in the safety module.

Supply voltage U
L
Supply the 24 V supply voltage U
BK
/U
24V
at a bus coupler or a suitable power terminal. The
7.5 V voltage U
L
is generated from this 24 V supply voltage in the bus coupler or power
terminal. It is supplied to the safety module via the VersaPoint potential jumper U
L
.
WARNING
Loss of the safety function when using unsuitable power supplies
Please note for the voltage supply at the bus coupler or power terminal that: Only power
supplies according to EN 50178/VDE 0160 (PELV) may be used. Please also observe the
points in Section "Electrical safety" on page 2.
The supply voltage U
L
is used to supply the bus controller board and the communications
power. For the technical data for the supply voltage U
L
, please refer to "Supply voltage U
L
(logic)" on page 61.
The maximum current carrying capacity for the supply voltage U
L
is 2 A.
This current carrying capacity can be reduced if certain terminals are used. Please refer to
the information in the terminal-specific data sheets.
