Safety Guidelines
쎲
Observe all safety and accident prevention regulations applicable to your spe-
cific application. Always disconnect all power supplies before performing
installation and wiring work or opening any of the assemblies, components and
devices.
쎲
Assemblies, components and devices must always be installed in a shockproof
housing fitted with a proper cover and fuses or circuit breakers.
쎲
Devices with a permanent connection to the mains power supply must be inte-
grated in the building installations with an all-pole disconnection switch and a
suitable fuse.
쎲
Check power cables and lines connected to the equipment regularly for breaks
and insulation damage. If cable damage is found immediately disconnect the
equipment and the cables from the power supply and replace the defective
cabling.
쎲
Before using the equipment for the first time check that the power supply rating
matches that of the local mains power.
쎲
Take appropriate steps to ensure that cable damage or core breaks in the signal
lines cannot cause undefined states in the equipment.
쎲
You are responsible for taking the necessary precautions to ensure that pro-
grams interrupted by brownouts and power failures can be restarted properly
and safely. In particular, you must ensure that dangerous conditions cannot
occur under any circumstances, even for brief periods.
쎲
EMERGENCY OFF facilities conforming to EN 60204/IEC 204 and VDE 0113
must remain fully operative at all times and in all PLC operating modes. The
EMERGENCY OFF facility reset function must be designed so that it cannot
ever cause an uncontrolled or undefined restart.
쎲
You must implement both hardware and software safety precautions to prevent
the possibility of undefined control system states caused by signal line cable or
core breaks.
쎲
When using modules always ensure that all electrical and mechanical specifi-
cations and requirements are observed exactly.
