Connection

Power supply X124
Table 11-2
Note
The two "+" and "M" terminals are jumpered in the connector and not in the device. This ensures
that the supply voltage is looped through.
The current consumption increases by the current consumption of DRIVE-CLiQ and the digital
outputs.
When using external power supplies (e.g. SITOP), the ground potential of the power supply
must be connected with the protective ground connection of the system (PELV).
