Safety instructions
Observe the following safety instructions! Disregarding these safety regula-
tions may result in death, serious personal injury or damage to equipment.
−
Personal and property protection are only guaranteed if the CPU is used
in accordance with its intended use.
−
Observe the safety regulations of electrical engineering and the employ-
er's liability insurance association!
−
Only perform work on the CPU when the power is switched off!
−
The CPU may only be installed by qualified personnel in accordance with
the specifications in the corresponding documentation.
−
Electrical work may only be performed by qualified electricians.
−
The CPU may only be commissioned by a person responsible for the
safety of the system. Only this person may connect the supply voltage.
−
Observe the necessary precautions when handling electrostatically sensi-
tive components (EN 61340-5-1, IEC 61340-5-1)!
−
Repairs to the CPU, particularly the opening of the housing, must only be
performed by the manufacturer.
−
Keep the operating instructions!
−
The operator of the CPU or plant is subject to the legal obligations
regarding safety at work. The Machinery Directive must therefore be taken
into account.
DANGER
Protection against dangerous voltages
−
When using the CPU, the user must be protected from touching haz-
ardous voltage.
−
You must therefore create an insulation concept for your system that
includes safe separation of the potential areas of ELV and hazardous
voltage.
−
Here, observe the insulation voltages between the potential areas speci-
fied for the modules and take suitable measures, such as using PELV/
SELV power supplies for the modules.
WARNING
Safety instructions for starting applications
When configuring the start conditions for your plant, take into account:
−
The machine or plant may only be started when it has been ensured that
no one is in the danger zone.
−
Comply with the requirements of EN ISO 13849-1 with regard to the
manual reset function. In this way, no machine movement may be initiated
and or dangerous situations may be caused, caused by e.g.:
−
Switching on devices
−
Acknowledgement of device error messages
−
Acknowledgement of block error messages in the application
−
Removal of start-up barriers
Please also consider these instructions in order to exclude an unexpected
machine start after acknowledgement with an "Operator Acknowledgement"!
