L+ L-, DC Bus Connection

Function, Pin Assignment
● Maximum allowed inductance: 100 µH (2 twisted single strands, 75 m
long)
● Parallel line routing where possible
The control voltage supply is routed to the connection X13 from above:
1 Lines to control voltage supply
Fig.5-14: Control Voltage Supply at X13
The input 0V is connected in conductive form to the housing po‐
tential. It is therefore impossible to use an insulation monitor at
+24V and 0V against housing.
WARNING
Before working on live parts: De-energize installation and secure power
switch against unintentional or unauthorized re-energization.
Wait at least 30 minutes after switching off the supply voltages to allow dis‐
charging.
Check whether voltage has fallen below 50 V before touching live parts!
The DC bus connection connects
● several drive controllers to one another
● a drive controller to additional components
HCS02.1E-W0012 drive controllers do not have a DC bus con‐
nection.
