Danger! – Dangerous electrical voltage!
Installation requires qualified electrician
•
Disconnect the power supply of the device.
•
• Secure against retriggering
• Verify isolation from the supply
Ground and short-circuit
•
• Cover or enclose any neighboring live parts.
• Follow the engineering instructions (IL) of the device concerned.
Only suitably qualified personnel in accordance with EN 50110-1/-2 (VDE 0105 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 equipoten-
•
tial bonding. The system installer is responsible for implementing this connection.
• Connecting cables and signal lines should be installed so that inductive or capacitive interfer-
ence does 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.
Deviations of the mains voltage from the nominal value must not exceed the tolerance limits
•
given in the specifications, otherwise this may result in malfunction and hazardous states.
• 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 result in
an automatic restart.
• Built-in devices for enclosures or cabinets must only be run and operated in an installed state;
desktop devices and portable devices only when the housing is closed.
Measures should be taken to ensure the proper restarting of programs interrupted after a
•
voltage dip or outage. This should not result in 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.).
