5.2 Installation and mounting PSC1 module
The module is only to be installed in switch cabinets that meet degree of protection IP54 as a
minimum.
The modules must be fastened vertically on a DIN rail
Note:
When used in non-closed rooms it must be ensured that the environmental conditions of the
individual assemblies (see technical data) are complied with.
cULus only:
Installation is only permitted indoors.
The ventilation slots must be kept adequately clear to ensure the circulation of air inside the module.
A free space of
30 mm must be provided at the top and bottom of the device. A stringing together of
expansion modules is permitted. A free space of 20 mm must be maintained to adjacent devices that
can generate waste heat.
5.3 Mounting backplane bus
The backplane bus comprises a 5-pin connector with spring contacts. As standard, all 5 contacts are
used on the connectors.
Remark:
Expansion modules do not have a dedicated power supply unit and rely on the backplane bus for a DC
supply. Basic modules (PSC1-C-10(-SDMx)(-FBx)) have a more powerful power supply unit and always
provide a supply on the backplane bus.
