- Check that the response time of the series meets the requirements of the safety
function to be implemented.
- The activation time of the series must be calculated taking into account the response
time of every single device.

Caution: if all OS safety outputs are connected directly to a safety contactor, we
recommend using fast switching diodes connected in parallel to the contactor coils.
6 INSTRUCTIONS FOR PROPER USE
6.1 Installation
Attention:Installation must be carried out by qualified staff only. The OS1 and
OS2 safety outputs of the device must be connected to the safety circuit of the machine.
The signalling output O3 is not a safety output and may not be used individually in a
safety circuit to determine safe state of guard closed.
- Do not stress the device with unintended, or greater than intended, bending and
torsion.
- Do not modify the device for any reason.
- Do not exceed the tightening torques specified in the present manual.
- The device carries out an operator protection function. Any inadequate installation or
tampering can cause serious injuries and even death, property damage, and eco-
nomic losses.
- These devices must not be bypassed, removed, turned or disabled in any other way.
- If the machine where the device is installed is used for a purpose other than that
specified, the device may not provide the operator with efficient protection.
- The safety category of the system (according to EN ISO 13849-1), including the sa-
fety device, also depends on the external components connected to it and their type.
- Before installation, make sure the device is not damaged in any part.
- Avoid excessive bending of connection cables in order to prevent any short circuits
or power failures.
- Do not paint or varnish the device.
- Do not drill the device.
- Do not use the device as a support or rest for other structures, such as raceways,
sliding guides or similar.
- Before commissioning, make sure that the entire machine (or system) complies with
all applicable standards and EMC directive requirements.
- Do not apply excessive force to the device once it has reached the end of its actua-
tion travel.
- Do not exceed the maximum actuation travel.
- The fitting surface of the device must always be smooth and clean.
- The documents necessary for a correct installation and maintenance are always
available in the following languages: English, French, German and Italian.
- Should the installer be unable to fully understand the documents, the product must
not be installed and the necessary assistance may be requested (see paragraph
SUPPORT).
- For HX •EE1-••• versions with electronic outputs: before commissioning the machine,
and periodically, check for correct switching of the outputs and correct operation of
the system comprising the device and associated safety circuit.
- For HX •EE1-••• versions with electronic outputs: in proximity of the device, do not
carry out arc welding, plasma welding, or any other process that may generate elec-
tromagnetic fields of intensity higher than the limits prescribed by the standards,
even when the device is off. Where welding operations are to be carried out in the
proximity of a previously installed device, it must first be moved away from the work
area.
- Always attach the following instructions to the manual of the machine in which the
device is installed.
- These operating instructions must be kept available for consultation at any time and
for the whole period of use of the device.
6.2 Do not use in the following environments
- In environments where continual changes in temperature cause the formation of
condensation inside the device.
- In environments where the application causes collisions, impacts or strong vibrations
to the device.
- In environments containing explosive or inflammable gases or dusts.
- In environments where ice can form on the device.
- In environments containing strongly aggressive chemicals, where the products used
