Mounting and wiring
Æ
General:
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.

Danger
•
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)
Æ
Inputs:
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.
V
Danger
•
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.
