Note
Protect connectors against soiling
Protect all connections from contamination during module installation!
Protection class IP67 can only be guaranteed if all cables and connectors are
connected!
Unused connections must be protected with the appropriate connectors (connector
sets see catalog)!
The modules are mounted with two M3 screws. The bolts must be longer than 15 mm. The fixing holes
are not threaded. Note when mounting that the overall height is increased further by the fieldbus
connections.
4.1.4.1 Mounting rail ZS5300-0001
The mounting rail ZS5300-0001 (500 mm x 129 mm) allows time-saving configuration of the modules.
The rail is made of 1.5 mm thick stainless steel (V2A) and features ready-made M3 threads. Use M5
screws (5.3 mm oblong holes) to attach the rail to the machine.
The rail is 500 mm long and enables the installation of 15 modules, with a distance of 2 mm between
them. It can be shortened as required for your particular application.
