Supply voltage U
Supply the supply voltage at a bus coupler or a power terminal. It is supplied to the safety
module via the VersaPoint potential jumper U
WARNING: Loss of the safety function when using unsuitable power supplies
Please observe the points in Section "Electrical safety" on page 1-2.

This current carrying capacity can be reduced if certain terminals are used. Please refer to
the information in the terminal-specific data sheets.
If the limit value of the potential jumpers U
a new power terminal must be used.
NOTE: Module damage due to polarity reversal
Polarity reversal places a burden on the electronics and, despite protection against
polarity reversal, can damage the module. Therefore, polarity reversal must be
prevented.
