22.4.1.1 Overview
M11967-3 v4
The flush mounting kit can be used for case sizes:
• 1/2 x 19”
• 3/4 x 19”
• 1/1 x 19”
• 1/4 x 19” (RHGS6 6U)
Only a single case can be mounted in each cut-out on the cubicle panel, for class IP54 protection.
Flush mounting cannot be used for side-by-side mounted IEDs when IP54 class
must be fulfilled. Only IP20 class can be obtained when mounting two cases side-
by-side in one (1) cut-out.
To obtain IP54 class protection, an additional factory mounted sealing must be
ordered when ordering the IED.
