b
If possible, select the mounting height of the top bracket such that the bracket
rests as close to the 90° bend of the protective housing end cap as possible.
b
In the event of vibratory/impact loads, mount additional stainless steel supporting
brackets at regular intervals on the device.
b
Tightening torque for the screws used to mount the bracket: 5 Nm … 6 Nm. Tight‐
ening torque for the screws used to secure the multiple light beam safety device in
the bracket: 4 Nm … 5 Nm. Higher torques can damage the bracket, while lower
torques are not secure enough to prevent the multiple light beam safety device
from moving.
b
Make sure that the sender and receiver are aligned correctly. The optical lens sys‐
tems of the sender and the receiver must be located opposite one another.
b
If necessary, use a spirit level to check that the components are parallel.

Mounting the reinforced stainless steel bracket
Overview
With the reinforced stainless steel bracket, the sender and receiver can be precisely
aligned with the device axis even after mounting.
The sender and receiver are mounted with two reinforced stainless steel brackets each.
The reinforced stainless steel bracket consists of two parts, which are placed onto each
other. The two parts are connected and the protective device secured with two M5
screws.
An M8 screw with washer is used to mount the reinforced stainless steel bracket on a
machine or profile frame.
Important information
NOTE
The following should be considered when mounting the reinforced stainless steel
bracket:
•
Select an appropriate screw length to prevent any risk of injury from an overrun
•
Take the reinforced stainless steel bracket and the machine or profile frame into
account when selecting the screw length,
