22.4.4.3 IED mounted with a RHGS6 case
M11953-3 v3
A 1/2 x 19” or 3/4 x 19” size IED can be mounted with a RHGS case (6 or 12 depending on IED size).
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 IEDs.

22.4.5 Side-by-side flush mounting
IP10329-1 v1
22.4.5.1 Overview
M11975-3 v3
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".
Use only the screws included in the mounting kit when mounting the plates and the
angles on the IED. Screws with wrong dimension may damage the PCBs inside the
IED.
