Steps for Mounting the Device
and receiver are aligned correctly. The optical lens systems
of sender and receiver must be located in exact opposition
to each other; the display elements must be mounted at
the same height. The system plugs of both devices must
point in the same direction.
➢ Take suitable measures to attenuate vibration if the
shock requirements are above the values given in the
“Data Sheet” section on page 35.
➢ Observe the safety distance of the system during
mounting. On this topic read the “Determining the
Safety Distance” on page 21.
➢ Connect a maximum of three systems into a cascaded
system.
➢ Always connect sender-sender and receiver-receiver
within a system configuration.
➢ Mount the safety light curtain such that the hazardous
point cannot be reached from below, above or behind
the safety light curtain and that the light curtain cannot
be repositioned.
ATTENTION: Special features to note
during mounting:
• Always mount the sender and receiver
parallel to one another.
• During mounting, make sure that sender

(below) standing behind, reaching below and reaching above
➢ Once the system is mounted, one or several of the
enclosed self-adhesive safety information labels must be
affixed.
♦ Use only labels in the language which the operators of
the machine understand.
♦ Affix the information labels such that they are easily
visible by the operators during operation. After
attaching additional objects and equipment, the
information labels must not be concealed from view.
♦ Affix the information label “Important Notices” to the
system in close proximity to sender and receiver.
♦ Operation with floating blanking: Affix the information
label for floating blanking to each sender or receiver so
configured. Mark the effective resolution on the
information label.
♦ For operation with reduced resolution: Affix the
information label for reduced resolution to each
sender or receiver so configured. Mark the effective
resolution on the information label.
