Installation and Maintenance

5.2Installation

There are several ways of installing the ELS:

●Installation on a 35 mm standard rail

●Installation on a SIMATIC S7-300 rail

●Installation in a 19" cabinet (along with other ELS modules in the 19" mounting system)

●Wall mounted

Note

•Remember that the ELS must only be installed horizontally (ventilation slits top/bottom see Figure 4). 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 range is not exceeded.

•During installation and operation, make sure that you adhere to the installation instructions and safety-related notices in this description and in the SIMATIC NET Industrial Ethernet Twisted Pair and Fiber-Optic Networks manual /2/.

•Unless specifically stated, the following installation options apply to all ELS switches.

Preparations

Remove the terminal block from the ELS and wire up the power supply lines as described in Section 4.1.2.
