Notice!
Installation must only be carried out by authorized specialist personnel.
Caution!
Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
In order to comply with EN50130-4:2011, shielded cable is required for the installation. The
shielded cable needs to be applied for all loops and stubs which are equipped with one or
more modules and for all inputs which are connected. The cable shield wire for the LSN cable
has to be connected properly according LSN specifications.
2 Address settings
Fit a rotary switch in the required position using a pan head slotted screwdriver (1.4).
Address (A) Operating mode
0 0 0 Loop/stub in LSN improved version mode with automatic addressing (T-taps not possible)

Notice!
The maximum cable length of all inputs connected to the loop or stub is 500 m in total.
Additionally, all outputs which are not electrically isolated from LSN must be included in the
total line length calculation (e.g. peripherals connected via C points).
The activation of the inputs IN 1 - 8 has to be carried out electrically isolated from LSN (e.g.
with relay contact, pushbutton, etc.).
The inputs must have a minimum activation time of 3.2 s.
