The choice between the two models must be made on the basis of the risk category attributed to
the machine, assessed in accordance with European standard
. The
model is suitable for all applications with maximum accident risk, both in terms of the
frequency with which the operator is exposed to said risk and the gravity of the danger (machines
listed in annex IV of Directive 2006/42/EEC). The
model is suitable for all other applica-
tions where the severity and frequency of exposure to the risk of accident is less.
To prevent shift of the laser light guard and consequently also of the protected area, it must be
fixed solidly and precisely respecting the instructions given in paragraph 13 "Mechanical Data".

Connection cables must be arranged so as to avoid accidental contact with, for
example, abrasive, hot or sharp objects which could cause dangerous damage to the cables
themselves. In the event of damage to the connection cables, do not use the device and
disconnect immediately from the power supply. Avoid the connection cables coming into
contact with water or damp surfaces. In addition, prevent access to the danger zone with other
fixed material barriers where this is not possible by the use of electro sensitive protective devices.
The
and
housings are electrically connected to the ground of the internal circuit, thus to
the
conductor of the connector. Contact between the housing and the chassis of the
machine (unless free of potential) must therefore be avoided. Failure to observe this precaution
could lead to damage of the units. This danger is totally avoided if the sensor units are correctly
fixed using special supports in electrically insulating material. Connection of other equipment to
the power source used to power the "RED-RL" device is not recommended. This could generate
electrical disturbance, jeopardising correct operation of the various parts of the device itself. If
liquid or foreign bodies of any kind penetrate into the device, stop using it immediately and
disconnect it from the power supply. The “RED-RL” device has been designed and produced in
such a way that the housing does not have to be opened for the device to be used. Given the
particular function of the device itself, removal of the heads of the aluminium housings of the
transmitter TX and receiver RX is prohibited. No attempt should be made to repair them. Always
contact the manufacturer only.

It
has to be adopted every precaution in order to reduce at the minimum the vibrations of the
machine, protect the device and its supports with mechanical shelters
to avoid direct
collisions.
Verify that the available power supply source corresponds to that operating one of the device in
use that must be verified from the data plate of both sections Transmitter (TX) and Receiver (RX).
The presence of a visible light laser emission, even if of low power as established by the enforced
european norms, could cause the use of the device dangerous. The protection of the person eye
from accidental flash turns out however assured, also without particular precautions, by the own
reactions defense like as an example the palpebral glare. It is however advised to avoid itself to
frontally fix or to direct the visible light laser source emitted from the Transmitter (TX).
