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.

Electromagnetic compatibility
USA:
This device complies with part 15 of the FCC Rules. Op-
eration is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, in-
cluding interference that may cause undesired operation.
This equipment has been tested and found to comply with

off and on, the user is encouraged to try to correct the in-
terference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and
receiver.
- Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV
technician for help.
This device complies with Part 15 of the FCC rules.
Changes or modifications not expressly approved by Sie-
mens Schweiz AG could void the user’s authority to oper-
ate the equipment.
