Switching power of Bb contact must be noted.
Fig. 11-3:
Example of generating the DC ZKS signal
Note:
All ZKS setups are controlled parallel on shared DC bus loop!
Any delay in the drop out of the main contactor also causes a
delay in the activation of the ZKS function.
=> See page 11-12: "Q1 Fuse and K1 Contactor".
CAUTION
Danger of damage!
If as a result of the application a manual actuation of
the load contactor K1 is necessary then the built in
DC bus dynamic brake setups must be protected by
applying switched mains voltage to the mains
connecting terminals of the DKC and BZM units in
use.
