NOTICE
The permissible drilling area highlighted in the drawing above are the same
for an enclosure that is supplied either with or without a gland plate.
For enclosures that are larger than size KTB MH 765015 the drilling areas
on sides C & D are based on two separate glanding areas. The separation
area is 60mm. Note: Whether gland plates are fitted or not, this separation
area has to be taken into account!
