1.4 Observe operating safety!
Never open the housing of the device! This could cause an electric short or even a
fire, which would damage your device. Do not modify your device!
The device is not intended for use by persons (including children) with limited physi-
cal, sensory, or mental capacities or a lack of experience and/or knowledge.
Keep packaging such as plastic films away from children. There is the risk of suffo-
cation if misused.
1.5 Consider the installation site!
To avoid any operating problems, keep the device away from moisture and avoid
dust, heat, and direct sunlight. Do not use the device outdoors.
The MOBALine-Booster is designed for DIN rails and should only be operated in-
stalled on a DIN rail.
By operating the device, the heat sinks attached to the sides get warm.
Make sure there is enough air circulation for the heat to dissipate.
Danger! Make sure
that you wait before using the device after any transport until the device has
reached the ambient air temperature. Great fluctuations in temperature or humidi-
ty may lead to moisture within the device caused by condensation, which can
cause a short.
1.6 Observe electromagnetic compatibility!
The device complies with the requirements of EMC directive 2004/108/EC and

3.3 Device designation in this manual
This manual relates to the MOBALine-Booster. For purposes of better readability the
designation booster is used in the following sections.
3.4 Function description
The MOBALine-Booster is a device for the amplification of MOBALine lines with regard
to output and range. For this purpose the MOBALine input signal is adapted and ampli-
fied.
The booster monitors the external supply voltage, the voltage of the MOBALine input
signal and the current of the MOBALine output signal (overload detection).
If one of the three monitoring systems detects an error, the booster switches off and
generates an alarm, which is signaled by the red alarm LED and with the alarm relay.
After five seconds the booster turns itself back on, provided that the monitoring system
has detected no further errors.
The signal is only amplified with the booster, therefore it is transparently transmitted,
i.e. without changes to content.
The booster is supplied by the external switch-mode power supply included in the
scope of supply, which can be operated directly from the power supply. If a power sup-
ply is available, the Power LED lights up.

The following illustration shows the block circuit diagram of the MOBALine-Booster:
3.4.1 Monitoring
The MOBALine-Booster carries out the following tests to check for correct operation:
Test
Threshold value
Supply voltage
Lower than 21 V error
MOBALine input voltage
Lower than 9 V effective error
MOBALine output current
Higher than 800 mA effective error
3.4.2 Alarm system
The alarm output and the alarm LED acknowledge an active error only if it persists for
at least two seconds without interruption.
If the alarm output and the alarm LED have been activated, they remain activated for at
least five seconds, even if all errors have disappeared earlier.

5 Mounting and installation
To mount the MOBALine-Booster and activate it for the first time, the following procedure can
be followed:
1. Mount the DIN rail in the desired place.
2. Fit booster and switch-mode power supply DR-30-24 onto the rail.
3. Connect supply between switch-mode power supply and booster with the power supply
cable included in the scope of delivery. NB: The power supply cable does not have con-
nections of equal length on both sides:
a. From the power supply cable connect the blue wire with the longer wire-end sleeve
to connection V- (connection 5 or 6) of the switch-mode power supply.
b. From the power supply cable connect the brown wire with the longer wire-end
sleeve to connection V+ (connection 3 or 4) of the switch-mode power supply.
c. From the power supply cable connect the blue wire with the shorter wire-end sleeve
to connection - (connection 3) of the booster.
d. From the power supply cable connect the brown wire with the shorter wire-end
sleeve to connection + (connection 4) of the booster.
4.
Important:
Turn ADJ trimmer at the switch-mode power supply with a screwdriver
clockwise as far as it will go (set output voltage to maximum).
5. If necessary, connect the alarm output of the booster (connections 5 and 6).
6. Connect the MOBALine output of the booster (connections 7 and 8).
7. Connect power supply to the switch-mode power supply.
a. Connect neutral conductor to switch-mode power supply at N (connection 1).
b. Connect phase to switch-mode power supply at L (connection 2).
c. The DC OK LED of the switch-mode power supply and the Power LED (green) of
the booster must now light up. If not, the installation must be checked.
d. The alarm LED of the booster lights up as this still has no input signal.
8. Connect the MOBALline input of the booster (connections 1 and 2).
9. After a short time the alarm LED of the booster must go out.

6 Application examples
Up to 2 boosters can be used in a series. If more boosters are used serially, the signal gets distorted and can
not be reliably detected by clocks anymore.
Example 1: Airport
Example 2: Office building
