3.7 Connection of supply voltages
The power supply for the MSDServoDriveAC-AC is separated into the supplies for
control and power sections. In the connecting sequence the control supply must always
be connected first, so that triggering of the MSDServoDriveAC-AC can first be
checked or the device can be parameterized for the intended application.
DANGER CAUSED BY HIGH VOLTAGE: Dangerous voltage may be applied
to the device, even if the device does not emit any visual or audible signals/
indications (e.g. with mains voltage applied to terminal X11 and missing
control supply (+24 V DC on X9/X10 or X44)!

ATTENTION! Generally apply suitable measures to provide adequate line
protection.

Table 3.5 Specification control supply Size1 to Size6A
NOTE: With sizes Size1 to Size4 the external voltage source not only supplies
the control unit, but also the output for the motor holding brake. If this
output is active, the current for the control unit plus the current for the motor
holding brake and additional current requirements for digital inputs and
outputs flows through terminal X9. Please take this into consideration when
rating the voltage source for the control unit and when looping through to
other equipment. The current demand for the individual devices can be found
in the appendix on page68 in tableA.15.
