Warning!
On the unplugged terminal block, it is possible to come into contact with parts that have voltage ap-
plied. For this reason, working on the unplugged terminal block is not permitted with voltages of 50 V
or higher.
4.32.5.4 Contact holding force
To ensure that cables maintain a secure contact with the terminal block, they must not be under too much stress.
If the holding force is exceeded, the cable will come loose from the terminal block and cause a malfunction.
