1.1 WARNINGS
The following safety warnings are used in this manual:
ATTENTION!
This alert symbol indicates necessary attention to potential hazard or risk. If not follow the
recommendation may cause dangerous situations to user or process.
ATTENTION!
The PSRW is built according following safety levels:
SIL3 IEC 61508
SILCL 3 IEC 62061
PL e / Cat 4 ISO 13489-1
However, the definitive SIL and PL of the application will depend on the number of safety components,
their parameters and the connections that are made, as per the risk analysis.
ATTENTION!
Perform a risk analysis to determine the appropriate safety level for your specific application, using all
the applicable standards.
ATTENTION!
The configuration of the PSRW is the responsibility of the installer or user.
ATTENTION!
The device must be installed/configured in accordance with the application specific, risk analysis and
all the applicable standards.
ATTENTION!
Reference should be made to the handbooks and the relative product and/or application standards to
ensure correct use of devices connected to the PSRW within the specific application.
ATTENTION!
The ambient temperature in the place where the system is installed must be compatible with the
operating temperature parameters stated on the product label and in the specifications.
ATTENTION!
For all matters concerning safety, if necessary, contact your country’s competent safety authorities or
the competent trade association.
