3.7 Electrical connections: General instructions
Cable glands All electric cables are fed from below through openings prepared in the enclo-
sure of the DIQ/S 28X and the DIQ modules. Cable glands with different clamp-
ing ranges are included with the DIQ/S 28X to provide sealing between the
cable and enclosure as well as for strain relief. Select the suitable cable gland
for the relevant cable type and cable diameter:
 Small , clamping range 4.5 to 10 mm.
This cable gland is suitable for all cables (earth cable after stripping the outer
insulation, see section 3.6) and sensor connection cables.
 Large , clamping range 7 to 13 mm.
This cable gland is required for cable sheaths with an outside diameter of
more than 10 mm and is screwed into the enclosure via an extension piece.
6 Fix the impact protection plate (Pos. 4) to the back of the DIQ/S 28X
with the bolts (Pos. 5).
If necessary, you can order more big cable glands (see
