Only use shielded connecting cables, e.g. cable type J-Y(ST)Y.
The above-specified cable lengths may not be exceeded. Excessive lengths can cause malfunctions.
The power supply must have a separate fuse protection.
The power supply of the access control element must be provided separately.
The recommended distance between cables and power lines is 10 cm.
If the locking device is monitored, a handle contact or door opening switch must be installed. The
switching of the contact allows for the locking device to be opened without setting off an alarm when
exiting the security zone.
