For connecting line cross sections of 35 mm² (AWG2) and
50 mm² (AWG1/0), use the accessory HAS05.1-004.
Routing Routing of the connection lines from the supply unit to drive systems and be‐
tween the drive systems:
●
Twist the lines with the minimum possible length of lay, but 120 mm as a
maximum
● With minimum mechanical distance to ground potential
● With a distance of at least 200 mm to control voltage lines
The figures below illustrate the correct DC bus connection for stacked drive
controllers. The illustrated way of connection keeps bare wire sections from
being situated directly vis-à-vis. This avoids voltage arcing.
Maximum Allowed Line Length at DC Bus Connection
The line length at the DC bus connection is limited to protect the devices. For
the maximum allowed line lengths between the electrical connections, see ta‐
ble below.

Tab.13-4: Maximum Allowed Line Lengths at DC Bus
Line length > 2 m between supply unit and drive controller
For arrangements of supply units which supply, for example, drive
controllers over line lengths > 2 m, take special measures:
●
Use HLC01 DC bus capacitor units at every drive system.
● Dimension the minimum size of HLC01 according to the pro‐
jected continuous power of the respective drive system:
47 μF per kilowatt [kW] of continuous power.
Example: 50 kW calculated continuous power in DC bus re‐
quires 2350 μF at this system, thus at least 1
