Warning!
Before commencing 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 inter-
ference 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 inter-
face 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 opera-
tion.
Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all oper-
ating 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 oper-
ated 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 inter-
locks 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 regu-
lations).
All shrouds and doors must be kept closed during operation.
