Illustration 21.1 YukonDrive® control supply connection
3.7 Connection of supply voltages
The voltage supply to the YukonDrive® is separate for the control and power sections. The control supply should always
be connected first, so that the device can be parameterized with DriveManager 5 and, above all, set to the correct
power supply.
Attention!
Only when the mains voltage has been set and the YukonDrive® 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 according to EN 50178 or EN 61800-5-1
Table 21.2 YukonDrive® control supply specification
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 figure 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 BG2 to BG4 may be two to three times the operating current.
