5.3 Connectors with non-pluggable input
Some gesis® SPZ distribution boxes do not have a pluggable input. In this case, a cable
screw gland or a T-head rail can be used as an input. The connections must be wired directly
to the installed connection points. Variants with a flat cable adapter are already wired
internally and just have to be connected to the flat cable.
5.4 Fitting the flat cable adapter to the flat cable

If your gesis® SPZ distribution box is designed for decentralized data distribution, the
distribution box will feature recesses for keystone elements. The relevant elements must be
installed on site in accordance with standards.
5.6 Connecting the earthing point
In order to ground the gesis® SPZ distribution box, connect the protective conductor
connections to the ground connections on the housing and, if applicable, the cover in
accordance with standards.
6Commissioning
All international, national and regional guidelines, standards, safety instructions and safety
regulations must be observed throughout the entire life cycle of the product.
The distributor is fully functional once it has been mounted and installed correctly. It may
be necessary to reset e.g. the switching and protective devices. If necessary, carry out a
functional test of the switching and protective devices.
Distribution boxes with electronic components may require commissioning and
configuration. The necessary manuals are enclosed with the distribution box and can be
found on the manufacturer's homepage.
During installation and commissioning, you must make sure that the necessary EMC
directives are complied with.
