Mounting and wiring
ÆGeneral:
It is recommended that the actuator is installed in two
flush sockets connected to one another (cf. fig. 2). One
socket (A) can accommodate, e.g., a series switch (C) as
well as the bus and extension connection. The other
socket (B) accommodates the actuator and the 230 V
terminals. The 6-pole connection lead (D) is guided
through the socket connection.

VDanger
•The device must be mounted and commissioned
by an authorized electrician.
•When connecting the device, it should be
ensured that the device can be isolated.
•The device must not be opened.
•For planning and construction of electric
installations, the relevant guidelines, regulations
and standards of the respective country are to be
considered.
•During installation, ensure adequate insulation
between mains voltage and bus or extensions! A
minimum spacing should be maintained
between bus / extension cable cores and mains
voltage cable cores of at least 4 mm.
(cf. figure 3)
ÆInputs:
Two extension inputs can be used for the connection of
potential-free contacts for local control or as binary inputs.

Caution
•To avoid disruptive EMI irradiation, the lines of the
inputs should not be laid parallel to lines conducting
mains voltage.
•Input A (green), input B (yellow) and reference
potential (com) (white and brown) must not
connect to inputs or reference potential (com) of
other devices.
VDanger
•On no account should you connect mains voltage
(230 V) or other external voltages to the extension
inputs! Connection to an external voltage would
endanger the electrical safety of the entire KNX/EIB
system (SELV / no galvanic isolation)!
People can be at risk, equipment and devices can be
destroyed!
•Unused cable cores of the 6-pole connection lead
are to be insulated from one another and from
external voltages.
