Safety Notes!
Before starting the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit.
Cover or enclose neighboring units that are live.
Follow the engineering instructions of the device concerned.
Only suitably qualified personnel in accordance with EN 50 110-1/-2 (VDE 0 105 Part 100) may work on
this device/system.
Before installation and before touching the device ensure that you are free of electrostatic charge.
The functional earth (FE) must be connected to the protective earth (PE) or to the potential equalization.
The system installer is responsible for implementing this connection.
Connecting cables and signal lines should be installed so that inductive or capacitive interference do not
impair the automation functions.
Install automation devices and related operating elements in such a way that they are well protected
against unintentional operation.
Suitable safety hardware and software measures should be implemented for the I/O interface so that a
line or wire breakage on the signal side does not result in undefined states in the automation devices.
Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power supply units
complying with IEC 60 364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
Deviations of the mains voltage from the rated value must not exceed the tolerance limits given in the
specifications, otherwise this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating modes of the
automation devices. Unlatching the emergency-stop devices must not cause restart.
Devices that are designed for mounting in housings or control cabinets must only be operated and
controlled after they have been installed with the housing closed. Desktop or portable units must only
be operated and controlled in enclosed housings.
Measures should be taken to ensure the proper restart of programs interrupted after a voltage dip or
failure. This should not cause dangerous operating states even for a short time. If necessary, emergency-
stop devices should be implemented.
Wherever faults in the automation system may cause damage to persons or property, external measures
must be implemented to ensure a safe operating state in the event of a fault or malfunction (for example,
by means of separate limit switches, mechanical interlocks etc.).
The electrical installation must be carried out in accordance with the relevant regulations (e. g. with
regard to cable cross sections, fuses, PE).
All work relating to transport, installation, commissioning and maintenance must only be carried out by
qualified personnel. (IEC 60 364 and HD 384 and national work safety regulations).
All shrouds and doors must be kept closed during operation.
