2.2 General safety instructions
WARNING!
● It is absolutely essential that you also observe the safety instructions in
the system manual and the "Functional safety" manual for your automa-
tion system.
● The following application areas are expressly excluded for the DU 3xx/x
without completing a special evaluation relating to the application and
implementing the necessary measures in the installation relating to the
operating conditions:
● Use in areas where there is a risk of explosion or fire
● Use in the mining sector
● Use in outdoor areas
● Use in wet rooms or rooms with the risk of splashing water
● Use in environments with heavily polluted air
● Use in environments with harmful solutions, steams or radiations
● Use in non-stationary applications
● Usage in environments with constant vibrations
● Direct use on a DC motor
● The module is defined as "open type equipment" (UL 508) or as "open
equipment" (EN 61131-2) and must therefore be installed in a control
cabinet.
● The DU 3xx/x contains safety-relevant functions (e.g. STO). For safety-
relevant control tasks and personnel security a control of KEBA in the
variant with correspondent safety related peripheral devices must be
used. Details can be found in the safety manual "Functional safety".
● At the developement of the the standard EN ISO 13849-1 or other stan-
dards for description of the functional safety were not considered.
Caution
Improper use of the assembly or the control system leads to irreparable
damage!
● Turn off the power supply before inserting or removing the module. Oth-
erwise, the module can be destroyed or undefined signal states can lead
to damage of the control system.
● If there are further power supply units in the system, they must also be
turned off, to ensure that no electrical voltages are present at all connec-
tions of the module.
KEBA shall assume no liability or warranty for consequential losses, which
may arise of:
● Disregard of directives and standards
