Note
Note or pointer
While mounting the modules, protect all connectors, especially the IP­Link, against contam­
ination! Only with connected cables or plugs the protection class IP67 is guaranteed!
Unused connectors have to be protected with the right plugs! See for plug sets in the cata­
logue.
Modules with narrow housing are mounted with two M3 bolts.
Modules with wide housing are mounted with two M3 bolts to the fixing holes located at the corners or
mounted with two M4 bolts to the fixing holes located centrally.
The bolts must be longer than 15 mm. The fixing holes of the modules are not threaded.
When assembling, remember that the fieldbus connectors increases the overall height. See chapter
accessories.
Mounting Rail ZS5300­0001
The mounting rail ZS5300­0001 (500 mm x 129 mm) allows the time saving assembly of modules.
The rail is made of stainless steel, 1.5 mm thick, with already pre­made M3 threads for the modules. The rail
has got 5.3 mm slots to mount it via M5 screws to the machine.
Fig. 58: Mounting Rail ZS5300­000
The mounting rail is 500 mm long, that way 15 narrow modules can be mounted with a distance of 2 mm
between two modules. The rail can be cut to length for the application.
Mounting Rail ZS5300­0011
The mounting rail ZS5300­0011 (500 mm x 129 mm) has in addition to the M3 treads also pre­made M4
treads to fix 60 mm wide modules via their middle holes.
Up to 14 narrow or 7 wide modules may be mixed mounted.
