K107USB INSTALLATION RULES
This module has been designed for mounting on a DIN 46277 rail. Assembly in vertical position is
recommended in order to increase the module's ventilation, and no raceways or other objects that
compromise aeration must be positioned in the vicinity.
Do not position the module above equipment that generates heat; we recommend positioning the module in
the lower part of the control panel or container compartment.
Inserting the module in the rail
1) Attach the module in the upper part
of the rail.
2) Press the module downwards.
In case of long connections or noisy environments, it is advisable to use screened cables for the RS485 line
(refer to Electrical Connections section).
