1Safety Information
The safety information indicates possible hazards and provides
information about how you can avoid hazardous situations.
Therefore please observe the safety information given for your
own and other people's safety.
1.1 General
The PROFIBUS Compact Repeater is only used as part of a complete
system.
!
The operator of a machine system is responsible for observing
all safety and accident prevention regulations applicable to the
application in question.
During configuration, safety and accident prevention rules
specific to the application must be observed.
Emergency OFF facilities according to EN 60204 / IEC 204
must remain active in all modes of the machine system. The system
must not enter an undefined restart.
Faults occurring in the machine system that can cause damage
to property or injury to persons must be prevented by additional
external equipment. Such equipment must also ensure entry into a safe
state in the event of a fault. Such equipment includes electromechanical
safety buttons, mechanical interlocks, etc. (see EN 954-1, risk
estimation).
Never execute or initiate safety-related functions using the
operator terminal.
Attention!
1. Use 60/75 °C copper wire only
2. Suitable for pollution degree 2 environment only.
3. Connect to 5 V bus only or Connect to 24 V bus only for devices
700-690-0CA12, 700-690-1BA12 and 700-690-1BB12.
4. See manual for all input and output ratings
5. Maximum surrounding air temperature is 60 °C

1.2 Restriction of access
The PROFIBUS Compact Repeater is an open item of equipment
and must only be installed in electrical equipment rooms,
cabinets or housings. Access to the electrical equipment rooms,
barriers, or housings must only be possible using a tool or key and
only permitted to personnel having received instruction or
authorization. See also Chapter 2.
Only authorized persons
must have access to the
P
ROFIBUS Compact
R
epeaters!
1.3 Target group for these instructions
These instructions are addressed to project planners and installers
of PROFIBUS Compact Repeater.
It is intended as a reference work for project planners. It provides
the installing technician with all the necessary data.
The PROFIBUS Compact Repeater is intended for use in a
PROFIBUS network only. For that reason, the configuring
engineer, user, and installing technician must observe the
standards, safety and accident prevention rules applicable in the
particular application. The operator of the automation system is
responsible for observing these rules.
1.4 Use as intended
The PROFIBUS Compact Repeater must only ever be used as
described in these instructions.
1.5 Avoiding use not as intended!
Safety-related functions must not be controlled using the
PROFIBUS Compact Repeater alone.
1.6 Symbols used
The following symbols are used in this manual.

2Installation and Mounting
The PROFIBUS Compact Repeater must be installed according to
VDE 0100 IEC 364. The PROFIBUS Compact Repeater has degree
of protection IP20.
Ambient temperature: 0 ºC – 60 ºC.
Before you start installation work, all system components must
be disconnected from their power source. Danger of electric shock!
During installation, the safety and accident prevention rules
that apply to the specific application must be followed (e.g. protection
against static discharges).
The PROFIBUS Compact Repeater is plugged directly into the SUB
D female connector of the PROFIBUS station instead of the
normal PROFIBUS device connector. It is locked in place with the
two screws on the sides.
Via the SUB D female connector, a diagnostic device or a stub line
can be connected. The front panel must be accessible in this case.
The cables of the PROFIBUS are routed downward out of the
repeater housing. There must be room for the PROFIBUS cables
here.
If the PROFIBUS Compact Repeater is at the end of a segment, the
termination must be ON.
If the PROFIBUS Compact Repeater is in the middle of a segment
(e.g. to start a stub line), you must switch the termination OFF.

3Short Description of the PROFIBUS Compact
Repeater
3.1 Application and function description
The PROFIBUS Compact Repeater is a normal PROFIBUS Compact
Repeater despite its small dimensions. It regenerates the electrical
signal arriving on the bus line and retransmits it. The level, edge
steepness, and mark-to-space ratio of the signals are reproduced
exactly. At the same time, it electrically isolates the receive lines
from the transmit lines.
These functions can be used
1.) to add a further segment to an existing PROFIBUS (in series or
as a stub line). This increases the possible number of stations on
the PROFIBUS by another 32.
2.) to cover long cable distances without any reduction in data
transmission rate. Up to three PROFIBUS Compact Repeaters can
be connected in series.
The PROFIBUS Compact Repeater is looped into the PROFIBUS in
place of a normal PROFIBUS connector. This permits the
extension, segmentation or branching of the PROFIBUS without
extensive installation. The device is plugged into the PROFIBUS
Compact Repeater and supplies the PROFIBUS Compact Repeater
with the necessary power (+5V). This is done via the SUB D
connector.
The PROFIBUS Compact Repeater permits transmission rates of
9.6 Kbps to 12 Mbps.
3.2 The LED display and its meaning
The front of the housing of the PROFIBUS Compact Repeater
contains a small white surface (see Fig. on Page 8). Behind this
white surface, you will find three LEDs that show you the
operating status of the PROFIBUS Compact Repeater and the
connected PROFIBUS Segment 2.

3.3 Connections
The PROFIBUS is connected to the PROFIBUS Compact Repeater
via a terminal block, see Fig. 3-1. To do this, the PROFIBUS
Compact Repeater must be opened. The shielding is grounded via
the metallized repeater casing.
Power supply via Sub D connectors of the PROFIBUS station

B1 red cable
Segment 2 A2 green cable
B2 red cable
SUB D female connector
An operator panel or programming unit can be connected to the
Sub D female connector of the PROFIBUS Compact Repeater. The
SUB D female connector can also be used for a PROFIBUS stub
line. The SUB D female connector is connected to Segment 1.
