21.4.4.3 IED in the 670 series mounted with a RHGS6 case
An 1/2 x 19” or 3/4 x 19” size IED can be mounted with a RHGS (6 or 12 depending
on IED size) case. The RHGS case can be used for mounting a test switch of type
RTXP 24. It also has enough space for a terminal base of RX 2 type for mounting of,
for example, a DC-switch or two trip relays.

21.4.5 Side-by-side flush mounting
21.4.5.1 Overview
If IP54 is required it is not allowed to flush mount side by side mounted cases. 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 required to mount the IEDs
separately. For cut out dimensions of separately mounted IEDs, see
section
"Flush mounting" .
