5.2Installation

OSMs/ESMs can be installed in several ways:

Installation on a 35 mm standard rail

Installation on a SIMATIC S7-300 rail

Installation in pairs in a 19" cubicle

Wall mounted

Note

Remember that the OSM/ESM must only be installed horizontally (ventilation slits top/bottom see Figure 25). To ensure adequate convection, there must be a clearance of at least 5 cm above and below the ventilation slits. You should also make sure that the permitted ambient temperature is not exceeded.

Preparations

1.Before installing, check whether the switch setting of the DIP switches is correct for your application. (see Section 4.2.4.1)

2.Remove the terminal block for power supply and signaling contact from the OSM and wire up the power supply and signal lines as described in Section 4.1.7.

3.Only for OSMs/ESMs with digital inputs:

When necessary, remove the terminal blocks for the digital inputs from the OSM/ESM and wire the input signals as described in Section 4.1.8.
