Procedure
1.
Mount the mounting bars onto the wall (4).
See section
"Wall mounting dimensions" for mounting dimensions.
Depending on the wall different preparations may be needed like drilling and
inserting plastic or expander plugs (concrete/plasterboard walls) or threading
(metal sheet wall).
2.
Make all electrical connections to the IED terminal.
It is much easier to do this without the unit in place.
3. Mount the side plates to the IED.
4. Mount the IED to the mounting bars.
5.3.4.3 How to reach the rear side of the IED
The IED can be equipped with a rear protection cover, which is recommended to
use with this type of mounting. See figure
14.
To reach the rear side of the IED, a free space of 80 mmis required on the unhinged
side.
