Mounting Procedure For Flush Mounting - ABB Relion 670 Series RES670 Technical Manual

Section 21
IED hardware
21.4.1.2
812
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.
