Installation box / panel for TRA
5.1 Requirements
Please read Sections 5.1 "Panel requirements" and 5.3 "EMC compliant panel" in
the TX-I/O engineering and installation guide [8] prior to engineering and executing
the installation box.
Observer the following for mounting and installation.
– Installation depth
– Maintain sufficient cable distance to be able to easily snap on and remove the
screw terminal blocks, even if the automation stations are mounted.
– Room automation stations can be mounted directly next to one another; a
distance of ca. 2 cm is recommended, however, for facilitate access.
– Reserve sufficient free space for subsequent extensions.
The room automation stations and TX-I/O modules are designed for installation on
standard rails (prerequisite to establishing the island bus connection using TX-I/O
modules).
Permissible standard rails:
Top hat rails TH35-7.5 as per EN60715 (35 x 7.5 mm).
Other top hat rails that meet the following conditions:
– Material thickness exterior max. 1 mm, min. 3 mm in depth
– Internal opening at least 25 mm.
