Danger!

Dangerous electrical voltage!

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 neighbouring units

that are live.

• Follow the engineering instructions

IL (previously AWA) 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 potential equalisation.

The system installer is responsible

for implementing this connection.

• Connecting cables and signal lines

should be installed so that inductive

or capacitive interference 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.

• 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 (VDE 0100 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 60204-1 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.).
