Intended Use The device is only approved for appropriate and intended use. Ignoring these
instructions will void any warranty and absolve the manufacturer from any
liability.
The device must only be operated in the specified ambient temperature range and
at the specified relative humidity without condensation.
The I/O modules of the distributed I/O system act as an interface between
signals from the hazardous area and the non-hazardous area.
The I/O modules, adapters, and power supplies of the distributed I/O system
must only be used together with the respective backplanes.
Observe the product information sheets for the respective backplanes.
Improper Use Protection of the personnel and the plant is not ensured if the device is not being
used according to its intended use.
Mounting and Installation Prior to mounting, installation, and commissioning of the device you should
make yourself familiar with the device and carefully read the product
information sheets.

Chapter 1 Safety
Do not mount the device at locations where an aggressive atmosphere may
be present.
Do not mount a damaged or polluted device.
The device is designed for use in pollution degree 2 and overvoltage category II
according to IEC/EN 60664-1.
If the device has already been operated in general electrical installations, the
device may subsequently no longer be installed in electrical installations used in
combination with hazardous areas.
If circuits with type of protection Ex i are operated with non-intrinsically safe
circuits, they must no longer be used as circuits with type of protection Ex i.
Avoid electrostatic charges, which could result in electrostatic discharges while
installing or operating the device.
Observe the installation instructions according to IEC/EN 60079-14.
Intrinsically safe circuits of associated apparatus (installed in non-hazardous area)
can be led into hazardous areas. Observe the compliance of the separation
distances to all nonintrinsically safe circuits according to IEC/EN 60079-14.
The respective peak values of the field device and the associated apparatus with
regard to explosion protection should be considered when connecting
intrinsically safe field devices with intrinsically safe circuits of associated
apparatus (verification of intrinsic safety). Make sure to observe
IEC/EN 60079-14 and IEC/EN 60079-25.
Do not push the I/O modules, adapters, and power supplies into the slots with
too much force. The rear connections of the devices may be damaged if using
excessive force. In this case, the explosion protection can no longer be ensured.
The backplane connections are non-intrinsically safe.
Connection or disconnection of energized non-intrinsically safe circuits is only
permitted in the absence of a potentially explosive atmosphere.
The device must be disconnected from the power supply prior to installation and
maintenance. The power supply may be activated only after all the circuits
required for operation have been fully assembled and connected.
All non-intrinsically safe interfaces must only be connected to secure low
protective voltages (SELV/PELV), the maximum root mean square (Um) of
which must not exceed 60V DC for the power supply connections and 30V AC/
DC for the bus connection. The distributed I/O station must only be connected
to the power supply voltages as specified on the type label.

Safety Chapter 1
Additional Requirements for Cables and Connection Lines
Observe the following points when installing cables and connection lines:
•Observe the permissible core cross-section of the conductor.
•The insulation stripping length must be considered.
•When installing the conductors the insulation must reach up to the
terminal.
•If you use stranded conductor, crimp on wire end ferrules.
•Never pull the cable. A wire could become loose from the terminal and
protection against electric shock can no longer be ensured. Always pull the
terminal.
•Connectors for non-intrinsically safe circuits must be mechanically
secured.
•The non-intrinsically safe cables have to be fixed with cable ties at the
intended fixtures.
•Unused connection lines must be either connected to terminals or securely
tied down and isolated.
Surrounding Enclosure The device may only be installed and operated in Zone 2 or Class I, Div 2 if it has
been mounted in a surrounding enclosure with degree of protection IP54
according to IEC/EN 60529. The surrounding enclosure must correspond to
equipment protection level Gc.
The device may only be installed and operated in Zone 22 if mounted in a
surrounding enclosure, which corresponds to equipment protection level Dc.
To ensure the degree of protection:
•All seals must be undamaged and correctly fitted.
•All screws of the surrounding enclosure/surrounding enclosure cover must
be tightened with the appropriate torque.
•Only cable of the appropriate size must be used in the cable glands.
•All cable glands must be tightened with the appropriate torque.
•All unused cable glands must be sealed or plugged with corresponding
stopping plugs.
Operation, Maintenance,
Repair
Observe IEC/EN 60079-17 for maintenance and inspection.
When energized, the surrounding enclosure may only be opened for maintenance
in Zone 2 or Class I, Div 2 if non-intrinsically safe circuit connections are
protected by a cover with a degree of protection IP30.
If the seal on the enclosure cover or a seal on the cable gland is damaged, the seal
must be replaced with a new seal provided by the manufacturer.

Introduction Distributed I/O stations are signal modification devices that act as an interface
for signals between field devices and process control systems. The individual
components, i.e., the I/O modules, adapters, and power supplies, are plugged into
the slots on the backplane. The EtherNet/IP adapter, 1719-AENTR, forms the
interface between the I/O modules and the process control system. Power
supplies are used to power the I/O modules and adapters.
This manual sets out how to work with the hardware. For information on how to
configure the adapter and I/O modules, refer to the Add-on Profile Help.

Backplanes Function
Backplanes are used to hold adapters, power supplies, and I/O modules. Fixed
slots are reserved on the backplane for adapters and power supplies. Slots for I/O
modules have equal status, meaning functions can be arranged side by side as
required.
