Only a single case can be mounted in each cut-out on the cubicle panel, for class
IP54 protection. The screws from the IED shall be used to fasten the fasteners to
the IED.
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.
