Product description
Connectors, buttons and LEDs description
The TAI4 Contact Interface is a 4-fold KNX binary input to sensor
contacts and to control/switch/operate KNX devices via classical
conventional switches and push buttons. The input module is suitable to
process binary signals of potential-free contacts. Due to its small
housing (diagonal of 50 mm) TAI4 finds enough room in a flush-
mounted box (Ø 60 mm) behind the switch. The connecting cable pairs
of 28 cm can be extended up to 10 m when twisted.
Designed for potential-free contacts such as conventional switches,
contact sensors and push buttons, TAI4 provides a 3.3 V sensing voltage
for contact scanning. All usual input functions like switching, dimming,
shutters, blinds control, counter and scenes can be used in a common
way.
Requirements of Directives EMC, RoHS and LVD are met. Standards for
residential, commercial, and industrial environments are fulfilled. The

Mounting, commissioning and safety notes
Installation and maintenance
•
After connection to the KNX bus system, the device works with its
default settings as intended
•
Warning
: Do not connect to 230 V. The device is supplied by the
KNX bus and does not require any additional external power supply
•
The device may only be installed and put into operation by a
qualified electrician or authorized person
•
For planning and construction of electric installations the appropriate
specifications, guidelines and regulations in force of the respective
country have to be complied
•
The device must not be mounted in a box together with 230 V devices
and/or 230 V cables
•
Combinations of a push button device connected to both the TAI4
and a 230 V device (or sockets) at the same time are not allowed
•
Ensure that there is a safety separation (SELV) between connected
signal cables (including extensions) and other current and voltage
carrying devices and cables
•
When connecting the TAI4, ensure that it can be isolated
•
Prevailing safety and accident prevention rules must be heeded
•
Connect the KNX bus line as for common KNX bus connections with a
KNX bus cable, to be stripped and plugged into a KNX TP connector
•
Do not damage electrical insulations during connecting
•
For changing the configuration use the ETS
•
The housing must not be opened
•
Installation only in dry locations
•
Accessibility of the device for operation and visual inspection must be
provided
•
Protect the device from moisture, dirt and damage
•
The device needs no maintenance
•
If necessary, the device can be cleaned with a dry cloth
•
In the case of damage (at storage, transport) no repairs may be
carried out by unauthorized persons
