INM 5500 Rev 10165 2 2 2 OrientationAs noted earlier (see section 5.1.1), for optimum temperature performance the enclosuresshould be mounted on a vertical surface with the internal DIN rail horizontal.5 2 3 Mounting detailsSee Figure 5.2 for the dimensions and mounting hole distances, etc., of the three DX enclosures.The recommended method of mounting-described here-uses the four wall-mounting lugs suppliedwith each enclosure. An alternative method of mounting is by direct attachment to the mountingsurface through the corner holes.Note: When the wall-mounting lugs are used to attach the enclosures, the overall depth of theenclosure is increased by an additional 3.3 mm (DX070) or 7 mm (DX170 and DX430).a) At each of the four corner fixing holes, insert one of the screws provided and use it to attacha fixing lug to the base of the enclosure.b) Each lug can be used in one of two positions as shown in Figure 5.2.c) Attach the lugs to the mounting surface with suitable fasteners.d) Diameters of fixing holes in lugs are 5.5mm (DX070) and 7.0mm (DX170 and DX430)e) Appropriate fixing hole distances are shown in Figures 5.2.5 2 4 Cable glandingAll cables into the enclosures must be glanded to IP65 standards to maintain this rating for theenclosure as a whole. Cable glands and gland plates are not supplied. Glanding requirements varyfor each enclosure as follows:DX070On the DX070, 'knockout' holes are provided, in two different sizes (15.5 mm and 21 mm), on theside faces of the base. See Table 5.7 for recommended cable glands.DX170The DX170 can accommodate one gland plate on each side - see figure 5.2 for details. Table 5.6 listssuppliers of suitable gland plate kits and Table 5.7 lists recommended glands.Table 5 6: Recommended gland plate kits for the DX170 and DX430 enclosures.Manufacturer/agentManufacturer’s part numberEnclosure DX170Hellermann Tyton TL-27/360Sarel 21128Table 5 7: Recommended cable glands for use with DX enclosures.GlandthreadsizeCablesizes(mm)Gland platehole size(mm)Weidmuller part nos Sarel part nosGland Locknut Gland LocknutPG9 5 to 8 15.2 951891 952216 08871 08881PG13,5 8 to 13 20.4 951893 952218 08873 08883Weidmuller (UK) http://www.weidmuller.co.ukSarel (UK) http://www.sarel.co.ukHellermann Tyton (UK) http://www.hellermantyton.co.uk
