) and stripping length 12 mm.
For every signal contact to be connected, make sure the following
requirements are met:
The electrical wires are voltage-free.
The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
See “General technical data” on page 54.
For every signal contact to be connected, perform the following steps:
For plugged connections: connect the signal contact lines with the
