5.3.6 Side-by-side flush mounting
5.3.6.1 Overview
It is not recommended to flush mount side by side mounted cases if IP54 is
required. If your application demands side-by-side flush mounting, the side-by-side
mounting details kit and the 19” panel rack mounting kit must be used. The
mounting kit has to be ordered separately. The maximum size of the panel cut out
is 19”.
With side-by-side flush mounting installation, only IP class 20 is
obtained. To reach IP class 54, it is recommended to mount the
IEDs separately. For cut out dimensions of separately mounted
IEDs, see section
"Flush mounting" .
When mounting the plates and the angles on the IED, be sure to use
screws that follows the recommended dimensions. Using screws
with other dimensions than the original may damage the PCBs
inside the IED.
