WARNING
Electrical and mechanical hazards
Electrical
shock
movement can cause serious injury or death.
Switch off main power to the elevator
control system and mark clearly that the
elevator is out of service.
Follow all applicable safety measures.
Make sure that your installation complies
with all applicable regulations and safety
measures.
NOTICE
Mechanical damage
Do not drill additional holes into the light
curtain.
Do not overtighten the mounting screws.
Mount the edges on a flat surface.
Do not bend the edges during transport or
during the installation.
Important:
It is very important to pay close attention to a proper cable
installation to ensure the highest possible reliability and
lifetime of the light curtain. Guide the cables of the emitter/
receiver to the control unit. A small bending radius reduces
the cable lifetime dramatically.
Figure 13:
Cable clamp (left) versus cable tie
Use the cable clamp to fix the cables (where the cable can
move (bend). Use cable ties only there when the cable does
not move as the doors open or close.
Install the cable guide wire to prevent possible cable swing.

Receiver and emitter need to mount at the same
height and both connectors are on top.
EN 81-20: Lowest beam should be less than 25 mm
above entrance level.
90°
Check the alignment of the edges. The receiver needs
to be mounted 180° to the emitter.
Important: Make sure the optical elements are facing
each other.
