System bus in variants RM-8940 ÷ RM-8944
is mounted on a DIN rail with a TS35 depth of 7.5 mm. The DIN rail is not a standard part of the delivery of the TC800 and is decided by the customer according to the mechanical design and construction of the switchboard or cabinet where the TC800 is installed. The use of a DIN rail with a depth of 15 mm is not possible for these bus variants.
The DIN rail according to ČSN EN 60715 with a width of 35 mm and a depth of 7.5 mm (see Fig. 1) is prescribed for use with the system bus ("frame") in variants RM-8940 ÷ RM-8944. The system bus snaps into this DIN rail and thus the foundation of the TC800 system is ready to complete the entire control system assembly.
