Product and Applications Description
The JB520C23 solar protection actuator is a KNX device with
one relay output. The device is installed in a 4 x 4 inch junc-
tion box. The bus is connected via a bus terminal block. The
actuator electronics are supplied via the bus voltage.
The JB520C23 may be used to control blinds, shutters, awn-
ings, windows, or doors.
The device is designed to drive (per channel) one AC 120V
drive (motor) with electromechanical limit switches or with
integrated electronics for disconnection at the limit positions.
For drives with electromechanical limit switches the actuator
can be configured to detect the status of the electromechan-
ical limit switches such that the travel time between the end
positions can be measured via a synchronization run. The
travel time of the blind / shutter is automatically measured
from the upper end position to the lower end position and
vice versa. The measurement is only reliable for drives with
electromechanical limit switches. The travel time cannot be
automatically adjusted for drives with integrated electronics
for disconnection at the limit positions. These drives have to
be controlled via a time limit. Their travel times have to be
manually measured as precisely as possible and configured in
the application program.
Parallel operation of several drives on one channel requires
using a special separation relay. If such a separation relay is
connected to the output to drive several drives in parallel,
then the travel time has to be configured manually.
If the device is configured for automatic detection of the
travel time, then parallel operation of several drives with elec-
tromechanical limit switches or mixed operation with drives
with integrated electronics for disconnection at the limit po-
sitions is not permitted.

Mounting and Dismounting
•Mounting of a JB module:
Option 1 (mounting inside a J-Box)
- Insert the thread of the JB module (B2) into the 1/2 inch
knockout between two adjacent J-Boxes (B1)
- Fasten the JB module (B2) with the 1/2 inch thread nut (B4)
- Remove the protective lid (B3) and connect the bus wire to
the bus terminal block (A4)
- Connect the wires from the device to the field wires using
wire nuts (not provided in package)
Option 2 (mounting outside of a J-Box)
- Insert the thread of the JB module (B2) into the 1/2 inch
knockout of the J-Box (B1)
- Fasten the JB module (B2) with the 1/2 inch thread nut (B4)
to the J-Box (B1)
- Connect the bus wire to the bus terminal block under the
protective cover (B3)
- Connect the wires from the device to the field wires using
wire nuts (not provided in package)
•Assignment of the Physical Address:
- A short push (< 2 s) of learning button (A6) enables the ad-
dressing mode, which is indicated when the LED is continu-
ously on (A5). The device returns to normal operating mode
(LED Off) automatically after receiving the physical address or
if the learning button is pushed again.
- A very long push (> 20 s) of the learning button resets the
device to factory settings. This is indicated by constant flash-
ing for 8 seconds.
- A long push (> 5 s up to 20 s) of the learning button enables
the Connection Test for commissioning with Desigo. This
mode can be disabled by a short push any time.
- Install the protective lid (B3) and fasten with screws (pro-
vided in package)
•Dismounting a JB module:
- Disconnect power to the module
- Remove the wire nuts and bus connection
- Unfasten the 1/2 inch thread nut (B4) connecting the JB
module (B2) to the J-Box (B1)
- Remove the JB module (B2) from the J-Box (B1)

Wiring
Slipping off/on bus connection blocks
The bus connection block consists of two components (C2.1
and C2.2) with four terminal contacts each. Take care not to
damage the two test sockets (C2.3) by accidentally connect-
ing them to the bus cable or with the screw driver (e.g. when
attempting to unplug the bus connection block).
Slipping off bus connection blocks
- Carefully put the screw driver to the wire insertion slit of
the bus connection block’s grey component (C2.2) and
- pull the bus connection block (C2) from the module.
Note
Don’t try to remove the bus connection block from the bottom
side. There is a risk of shorting-out the device!
Slipping on bus connection blocks
- Slip the bus connection block (C2) onto the guide slot of
the module and
- press the bus connection block (C2) down to the stop.
Connecting and Disconnecting bus cables
Connecting bus cables
- The bus connection block (D2) can be used with single
core conductors Ø 0.6…0.8 mm.
- Remove approx. 5 mm of insulation from the conductor
(D1) and plug it into the bus connection block (D2)
(red = +, grey = -)
Disconnecting bus cables
- Unplug the bus connection block (D2) and remove the bus
cable conductor (D1) while simultaneously wiggling it.
Connecting mains and load circuit:
Connect wires
-Connect wire leads using wire nuts.
