3 Installation<br />

3.1 Mounting of casing<br />

The <strong>ELC</strong> must be installed in a control cabinet with at least IP 54 protection (see<br />

EN 60529). Operation without a control cabinet or in a control cabinet with a<br />

lower degree of protection is not permitted.<br />

It is only permitted to install the appliance in the positions described in 3.1.1 or<br />

3.1.2. When installed vertically, as described in Fig. 1, the control connections<br />

must be positioned at the bottom and supply connections at the top. Installation<br />

must allow for the minimum spacing.<br />

The <strong>ELC</strong> should not be mounted in the immediate proximity of sensitive<br />

<strong>electronic</strong> equipment. An appropriate distance must be maintained to scatter<br />

field transformers or other inductors.<br />

The flow of cool air for the <strong>ELC</strong> must be safeguarded. The ambient temperature<br />

must not exceed the values prescribed in chapter 6.<br />

Ventilation must be provided for the switch cabinet.<br />

The amount of air necessary is determined by the size and positioning of the<br />

switch cabinet, the total electrical losses and the external temperature. Please<br />

consult your switch cabinet manufacturer. For the recommended throughput of<br />

air please see the technical data in chapter 6.<br />

Impure cooling air could affect the functionality of the <strong>ELC</strong>. This can be avoided<br />

by installing a fine air filter.<br />
