8.1. General information and useful data
Safety MUST be a part of our conscience.
The safety devices fulfil their safety function only if they are correctly
installed, in accordance with the Standards in force.
If you are not certain to have the expertise necessary to install the
device in the correct way, Pilz Technical Support is at your disposal
to carry out the installation.
The device uses fuses that are not self-resetting. Consequently, in
presence of short-circuits causing the cut-off of these fuses, both
units shall be sent to Pilz Technical Support department.
A power failure caused by interferences may cause the temporary
opening of the outputs, but the safe functioning of the light curtain will
not be compromised.
