NOTE
•
All in
puts and outputs of the device must be used only in the specified manner.
•
Enclosure rating IP65 cannot be guaranteed if the cable gland/blind plug are
missing or not fastened, or the fixing screws of the system plug are missing or not
fastened.
Wiring in accordance with EMC regulations
T
he quality of the shield is essentially dependent on the quality of the connection of the
screen. In general, the best shielding effect can only be achieved by applying the screen
at both ends using large area connections.
b
If it is not possible to connect the screen via threaded fittings (e.g. on bus nodes),
connect the screen physically close to the device using a metal clamp, e.g., to a
control cabinet chassis.
NOTE
•
If y
ou want to operate two safety laser scanners in a system (communication via
EFI), then the same earthing method must be used for both safety laser scanners.
•
If there is a protection earth (PE) in an installation, it can be used to connect the
functional earth (FE). A functional earth connection (FE) must never be used as a
protection earth (PE), however.
Functional earth
To achieve the specified EMC safety, the functional earth (FE) must be connected, e.g.,
to the central earth star point of the vehicle or system.
Since the safety laser scanner has no separate functional earth connection (FE), the
functional earth must, if necessary, be connected to the housing.
