Installation
3.1
Preparatory work
Before starting the installation, check that all required products are complete and functional.
Correctly mount/deburr or check profile cutouts, hardware drill holes and cable bushings in
accordance with Appendix A3 or the relevant enclosed installation instructions.
Thoroughly remove swarf.
Attention electronics: make sure the lock recess is free of swarf and clean!
Retract the connection cable on the secured side of the door. Take care not to kink or bend the cable
in the process. Provide for a sufficiently large cable loop (~ 50 mm)!
Protect the connection cable against abrasion.
(Recommendation: use protective hose B 5490 0308)
Provide a cable disconnection point in the area of the cable link to make it easier to remove the door.
Max. cable length from the lock to the control unit/junction box is 10 m (length of pre-assembled
cable). In addition, larger cable cross-sections may be required to prevent voltage drops (see Fig. 2).
