as BS 8519) to connect control module.. Protection box is made of calcium silicate plates.
■
Procedure
■
Use drill (drill size acc. to suit connecting cable Ø + 2 mm for seal up by mastic) and make holes (min. pitch of the holes
must be 30 mm), number of holes depends on the type of control module. It is possible to drill holes in any side of the
