Terminal Block L+, L- (DC Bus Connection)

WARNING
Function, Pin Assignment
A cable (to source of control voltage supply)
B contact bars
Fig.8-56: Connection points and connections of control voltage
Requirements on the connection to the 24V supply:
● maximum allowed inductance of 100 µH (2 twisted single strands, 75 m
long)
● parallel line routing where possible
The input 0V is connected in conductive form with the housing po‐
tential. It is therefore impossible to use an insulation monitor at
+24V and 0V against housing.
Lethal electric shock caused by live parts with more than 50 V!
● Wait at least 30 minutes after switching off power to allow discharging. To
shorten the waiting time until voltage has fallen below 50 V, you can use
a discharging device (see documentation "Rexroth IndraDrive - Drive Sys‐
tem" or, if existing, chapter "Appendix" in this documentation).
● 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 connec‐
tion.
