Subject to technical alterations
Installation
3.1.
Mounting of casing
The ELC must be installed in a control cabinet with at least IP 54 protection (see
EN 60529). Operation without a control cabinet or in a control cabinet with a lower
degree of protection is not permitted.
It is only permitted to install the appliance in the positions described in 3.1.1 und
3.1.2.
When installed vertically, the control connections must be positioned at the
bottom and supply connections at the top. Installation must allow for the
minimum spacing.
The ELC should not be mounted in the immediate proximity of sensitive electronic
equipment. An appropriate distance must be maintained to scatter field
transformers or other inductors.
The flow of cool air for the ELC must be safeguarded. The ambient temperature
must not exceed the values prescribed in chapter 6.
Ventilation must be provided for the switch cabinet.
The amount of air necessary is determined by the size and positioning of the
switch cabinet, the total electrical losses and the external temperature. Please
consult your switch cabinet manufacturer. For the recommended throughput of
air please see the technical data in chapter 6.
Impure cooling air could affect the functionality of the ELC. This can be avoided by
installing a fine air filter.
