ELC N6_N10-V3.1-09/11-GB subject to technical alterations
3 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.
The ELC may only be installed
vertically
(control connections at the bottom,
power connection at the top) allowing for at least the minimum spacing as
shown. No other positioning is possible.
The installation possibilities are shown in 3.1.1 and in 3.1.2.
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 in ELC must be safeguarded. The ambient temperature must
not exceed the values described in chapter 6!.
The switching cabinet has to be air conditioned in consideration of total electrical
losses and maximum ambient temperature.
If the air conditioning is realised by fans the minimum required air flow is
described in chapter 6. The better the cooling situation the higher the expected
lifetime
.
Impure cooling air could affect the functionality of the ELC. This can be avoided
by installing a fine air filter.
