3.7 Connection of supply voltage
The voltage supply to the MSD Servo Drive Compact is separate for the control and
power sections. The control supply should always be connected
first
, so that the device
can be parameterized with Moog D

5 and, above all, set to the correct
power supply.
ATTENTION! Only when the mains voltage has been set and the
MSD Servo Drive Compact restarted (if the mains voltage or switching
frequency has been changed) may the mains power supply be activated.
Otherwise the device may be destroyed!

• Internal polarity reversal protection
• The power supply unit used must have a safe and reliable
isolation against the mains system acc. to EN 50178 or
EN 61800-5-1

!
ATTENTION! Suitable measures must generally be applied to provide
adequate line protection.
DANGER FROM ElECTRICAl TENSION! When the mains voltage is switched
on at terminal X3 and there is no control supply (+24 V DC at X2), dangerous
voltage is connected to the device with no visual signal on the display or
acoustic indication by fan noise. If visible in the installed state, lED H1 (see
Fig. 3.1) indicates whether voltage is connected to the device. Even when H1
is out, X1 must be checked to ensure no voltage is connected.
NOTE: The start-up current for the supply voltage to the C2 to C4 may be
two to three times the operating current.
3.7.2 Connection of mains supply C2 and C3
NOTE: Before commissioning, the value of the connected mains voltage must
be set on the drive (factory setting = 3 x 230 V AC / 3 x 400 V AC).
