Flush mounting

Overview

The flush mounting kit are utilized 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.
