3.1 Order and Arrangement of the Modules

The RSTi-EP system elements are designed to be installed on a profile rail according to EN 60715 [1.4
x 0,26 in (35 × 7.5 mm)], a steel strip in accordance with Annex A of EN 60715, or a tin-plated steel
strip.
Note: A RSTi-EP station may be built up to a maximum length of 3.28 ft (1 m). Therefore, at most
82 modules (including max. 64 active modules) can be aligned on a network adapter.
The RSTi-EP station is usually installed on a horizontally positioned DIN rail.
Installation Position of the RSTi-EP Station on the DIN Rail (Horizontal Installation)
Installation on vertically positioned DIN rails is also possible. In this case however, the heat
dissipation is reduced such that the derating values change (refer to the section Current Demand and
Power Supply). In the case of vertical mounting, the network adapter must always be arranged as the
first module at the bottom and secured with an end bracket for vertical mounting.
