b
Mount t
he sender and receiver with the prepared mounting hardware. Tighten the
screws to a torque of 1.3 Nm ± 0.2 Nm. Higher torques can damage the module
housing while lower torques do not provide adequate fixation to prevent the safety
light curtain from moving in the event of vibrations. It is recommended that two
screws per module be used to secure the mounting.
b
When mounting, make sure that sender and receiver are aligned correctly. The
optical lens systems of sender and receiver must be located opposite one another.
b
Check the parallelism of the components using a water level or a straight edge, for
example.
Direct mounting
N
o special brackets are required to mount the sender and receiver. The modules can
be mounted directly on the machine frame. The modules can also be mounted on a
device column or profile frame.
The module housings are designed so that senders and receivers can be mounted with
the side or back to the mounting surface.
CAUTION
Risk of injury from protruding screws thread
When mounting through the machine or profile frame, the screws can present an injury
risk if too long.
b
Select the appropriate screw lengths to prevent any risk of injury from an over‐
hang.

Connect the sender and receiver
Connect t
he sender and receiver:
C1
Sender and r
eceiver automatically synchronize themselves electrically. An electrical
connection between both components is, therefore, required. Therefore, for the mac4
safety light curtain, only the receiver should be connected to the control.
b Connect the sender and receiver. Connect the 5-pin connection cable between
both ends of the cable to the yellow plug inserts.
b
Connect the receiver to the electrical control. Connect the 4-pin connecting cable
between the end of the cable to the black plug insert and control.
