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.
Eaton Safety instructions
Warning!
Dangerous electrical voltage!

• 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,
externalmeasuresmustbeimplementedto
ensureasafeoperatingstateintheeventof
a fault or malfunction (for example, by
means of separate limit switches,
mechanical interlocks etc.).

1 EZ204-DP
The EZ204-DP communication module was developed for
automation tasks using the PROFIBUS-DP fieldbus. The
EZ204-DP is a gateway and can only be used in conjunction
with the EZ700, EZ800 or EZD basic units. The EZ control
relay or EZD device with a PROFIBUS-DP gateway always
works as a slave station on the network.
