Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally

restarted.

• Verify isolation from the supply.

•Short circuit to earth.

• Cover or enclose neighboring units that

are live.

• Follow the engineering instructions (AWA)

of the device concerned.

• Only suitably qualified personnel in

accordancewithEN50110-1/-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 potential equalization. The system

installerisresponsibleforimplementingthis

connection.

• Connecting cables and signal lines should

be installed so that inductive or capacitive

interferencedoesnotimpairtheautomation

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/Ointerfacesothatalineorwirebreakage

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 60364-4-41(VDE0100Part410)orHD

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.

Warning!

Dangerous electrical voltage!

• Emergency stop devices complying with

IEC/EN 60204-1 must be effective in all

operatingmodesoftheautomationdevices.

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,

externalmeasuresmust beimplementedto

a fault or malfunction (for example, by

means of separate limit switches,

mechanical interlocks etc.)
