5 .2 .2 .2 Orientation
As noted earlier (see section 5.1.1), for optimum temperature performance the enclosures
should be mounted on a vertical surface with the internal DIN rail horizontal.
5 .2 .3 Mounting details
See 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 supplied
with each enclosure. An alternative method of mounting is by direct attachment to the mounting
surface through the corner holes.
Note : When the wall-mounting lugs are used to attach the enclosures, the overall depth of the
enclosure 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 attach
a 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 glanding
All cables into the enclosures must be glanded to IP65 standards to maintain this rating for the
enclosure as a whole. Cable glands and gland plates are not supplied. Glanding requirements vary
for each enclosure as follows:
DX070
On the DX070, 'knockout' holes are provided, in two different sizes (15.5 mm and 21 mm), on the
side faces of the base. See Table 5.7 for recommended cable glands.
DX170
The DX170 can accommodate one gland plate on each side - see figure 5.2 for details. Table 5.6 lists
suppliers of suitable gland plate kits and Table 5.7 lists recommended glands.
