The safety terminal is supplied with communications power via the bus coupler, a VersaPoint controller, or a designated
power terminal in the station. Potential routing is used for the communications power in the VersaPoint station. For tech-
nical data, please refer to the data sheet for the bus coupler, VersaPoint controller, or power terminal used.

The safety terminal is supplied with main voltage U
M
via the bus coupler, a VersaPoint controller, or a power terminal in the station. Potential
routing is used for the main voltage in the VersaPoint station. For technical data, please refer to the data sheet for the bus coupler,
VersaPoint controller, or power terminal used.
WARNING: Loss of the safety function when using unsuitable power supplies
Only use power supplies according to EN 50178/VDE 0160 (PELV).
