Safety instructions

 General safety instructions

You operate this device with electricity. Improper usage of the device
entails the risk of physical injury or significant property damage. The
proper and safe operation of this device depends on proper handling
during transportation, proper storage and installation, and careful
operation and maintenance procedures.
 Before connecting any cable, read this document, and the safety

instructions and warnings.

 Operate the device with undamaged components exclusively.
 The device is free of any service components. In case of a damaged

or malfunctioning the device, turn off the supply voltage and return the
device to Hirschmann for inspection.

 Certified usage

 Use the product only for the application cases described in the

Hirschmann product information, including this manual.

 Operate the product only according to the technical specifications.

See “Technical data” on page 30.

 Connect to the product only components suitable for the requirements

of the specific application case.

 Device casing

Only technicians authorized by the manufacturer are permitted to open
the casing.
 Never insert pointed objects (narrow screwdrivers, wires, etc.) into the

device or into the connection terminals for electric conductors. Do not
touch the connection terminals.

 At ambient temperatures > 140 °F (60 °C):

The surfaces of the device housing may become hot. Avoid touching
the device while it is operating.

WARNING

UNCONTROLLED MACHINE ACTIONS

To avoid uncontrolled machine actions caused by data loss, configure all
the data transmission devices individually.

1.8 “FAULT” signal contact

The signal contact (“FAULT“, pin assignment see table 4) is used to monitor
the device function, and thus supports remote diagnostics. You can specify
the type of function monitoring in the Management.
You can also use the Management to set the signal contact manually and
thus control external devices.

The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:

 The failure of at least one supply voltage.
 The device is not operational.
 The failure of the connection on at least one port.

The report of the link status can be masked by the Management for each
port. In the delivery state, is deactivated.

 Failure of the ring redundancy reserve.
 Errors detected during the self-diagnostic test.
 Incorrect configuration of the HIPER-Ring or ring coupling.

The following condition is also reported in RM mode:

 Ring redundancy reserve is available. On delivery, there is no ring

redundancy monitoring.

You can also use the Management to set the signal contact manually and
thus control external devices.

and that are certified for a temperate range from −40 °F to +140 °F
(−40 °C to +60 °C).

Proceed as follows:

 Prepare the drill holes at the installation point.
 Mount the device on a level surface with four M5 screws.
 Seal all unused connections and ports with the appropriate protection

caps or protection screws.

See “Accessories” on page 35.

2.2.2 Grounding the device

Grounding the device is by means of a separate ground connection on the
device.

See “Device views” on page 13.

The overall shield of a connected shielded twisted-pair cable is connected to
the metal housing as a conductor.
 Connect the grounding conductor to the grounding screw at the device

housing.

 Use toothed washers to ensure good electrical conductivity at the

connection.

2.3 Wiring the connectors for supply voltage
and signal contact

The supply voltage and the signal contact are connected by means of a 5-pin
M12 connector.

See “Scope of delivery” on page 34.

Relevant for installations under UL conditions:
Use an UL approved power supply plug which is suitable for the voltage
range, the current and the ambient temperature range of this device, for
example the Lumberg RKC series. A pin assignment drawing of the power
supply connector is provided in table 4.

The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit with the higher output voltage supplies the device on its own. The
supply voltage is electrically isolated from the housing.

Note: With non-redundant supply of the mains voltage, the device reports a
power failure. You can prevent this message by applying the supply voltage
via both inputs, or by changing the configuration in the Management.

 Use a power supply cable which is suitable for the voltage, the current and

the physical load.
Hirschmann recommends a wire diameter of 0.5 mm² to 0.75 mm²
(AWG20 to AWG18).

 Use a back-up fuse suitable for the supply network.

See “General technical data” on page 30.

 Make sure that the disconnecting device is easily accessible for

disconnecting the device from the mains voltage.

Note: Connectors are not electrical isolating devices. Therefore, first plug the
connector into the power supply plug and then switch on the power supply.

 Mount the connector for the supply voltage and the signal contact on the

front of the device.

2.4 Operating the device

When you connect the supply voltage, you start up the device.

2.5 Connecting data cables

You have the ability to connect end devices or other segments to the ports of
the device via twisted-pair cables.

2.5.1 Twisted Pair ports

Note the following general recommendations for data cable connections in
environments with high electrical interference levels:

 Keep the length of the data cables as short as possible.
 Use optical data cables for the data transmission between the buildings.
 When using copper cables, provide a sufficient separation between the

power supply cables and the data cables. Ideally, install the cables in
separate cable channels.

 Verify that power supply cables and data cables do not run parallel over

longer distances, and that ideally they are installed in separate cable
channels. If reducing the inductive coupling is necessary, verify that the
power supply cables and data cables cross at a 90° angle.

 Use shielded cables (SF/UTP cables as per ISO/IEC 11801:2002).

 Connect the data cables according to your requirements.
 Connect the cable shield to the connector housing.
 Seal all unused ports with protection screws.

See “Accessories” on page 35.

2.5.2 Optical fiber ports

Verify that you connect LH ports only with LH ports, SX ports only with SX
ports, and LX ports only with LX ports.

 Connect the data cables according to your requirements.
 Seal all unused ports with the protection caps attached to the device.

3 Making basic settings

The IP parameters must be entered when the device is installed for the first
time. The device provides 6 options for configuring IP addresses:

 Entry via V.24 connection
 Entry using the HiDiscovery protocol via the application HiDiscovery or

Industrial HiVision

 Configuration via BOOTP
 Configuration via DHCP
 Configuration via DHCP Option 82
 Auto Configuration Adapter

Further information on the basic settings of the device can be found in the
user manual on the CD/DVD.

4 Monitoring the ambient air temperature

Operate the device below the specified maximum ambient air temperature
exclusively.

See “General technical data” on page 30.

The ambient air temperature is the temperature of the air at a distance of 2 in
(5 cm) from the device. It depends on the installation conditions of the device,
e.g. the distance from other devices or other objects, and the output of
neighboring devices.

The temperature displayed in the CLI and the GUI is the internal temperature
of the device. It is higher than the ambient air temperature. The maximum
internal temperature of the device named in the technical data is a guideline
that indicates to you that the maximum ambient air temperature has possibly
been exceeded.

5 Maintenance and service

 When designing this device, Hirschmann largely avoided using high-wear

parts. The parts subject to wear and tear are dimensioned to last longer
than the lifetime of the product when it is operated normally. Operate this
device according to the specifications.

 Relays are subject to natural wear. This wear depends on the frequency

of the switching operations. Check the resistance of the closed relay
contacts and the switching function depending on the frequency of the
switching operations.

 Hirschmann is continually working on improving and developing their

software. Check regularly whether there is an updated version of the
software that provides you with additional benefits. You find information
and software downloads on the Hirschmann product pages on the
Internet (www.hirschmann.com).

Note: You will find information about the complaints and returns procedures
