Multiple-Line Arrangement
For multiple-line arrangement of drive controllers, the connection for DC bus
and control voltage supply is realized with twisted cables.
Risk of damage to the drive controller!
NOTICE
●
The DC bus connections of stacked drive controllers must be correctly
interconnected.
●
Connect L+ connections only to other L+ connections and L- connec‐
tions only to other L- connections.
●
Observe the measures regarding maximum allowed line lengths and
minimum required line cross sections.
Minimum Requirements to Connection Lines
Dielectric Strength
The connection lines from the supply unit to the drive systems and between
the drive systems must have a dielectric strength of at least:
●
1000 V against each other
●
700 V against ground
Line Cross Section
Determine the minimum line cross section from supply unit to drive systems
and between drive systems by means of the rated current. For rated current,
use the higher value from the following calculations:
●
Calculate the mains-side phase current
●
Calculate the current in the branch with the greatest DC bus power
Minimum cross section UL
Use in the scope of UL requires the line cross section A ≥ 35 mm
2
(AWG2).
