Safety regulations
WARNING
Dangerous electrical voltage!
Serious injury and material damage may occur.
Before commencing the installation:
▶
Disconnect the power supply of the device.
▶
Ensure that the device cannot be accidentally restarted.
▶
Verify isolation from the supply.
▶
Earth and short circuit.
▶
Cover or enclose neighbouring units that are live.
▶
Follow the engineering instructions of the device concerned.
▶
Only suitably qualified personnel in accordance with EN 50110-1/
-2 (DIN VDE 0105 Part 100) may work on this device.
▶
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 tothe potential equalisation. The system installer is
responsible for implementing this connection.
▶
Connecting cables and signal lines should be installed so that in-
ductive 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 opera-
tion.
▶
Suitable safety hardware and software measures should be im-
plemented for the I/O interface so that a line or wire breakage on
the signal side does not result in undefined states in the automa-
tion devices.
▶
Ensure a reliable electrical isolation of the low voltage for the
24 volt supply. Only use power supply units complying with
IEC/HD 60364-4-41 (DIN VDE 0100 Part 410).
▶
Deviations of the mains voltage from the rated value must not ex-
ceed the tolerance limits given in the specifications, otherwise
this may cause malfunction and dangerous operation.
▶
Emergency stop devices complying with IEC/EN 60204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause uncon-
trolled operation or restart.
▶
Measures should be taken to ensure the proper restart of pro-
grams interrupted after a voltage dip or failure. This should not
cause dangerous operating states even for a short time. If neces-
sary, 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 in-
terlocks etc.).
