Version: 50F
All contactors in the area of the converter must be equipped with an appropriate
suppressor circuit.
All contactors or comparable switching amplifiers must be equipped with appropriate
protective circuitry (e.g. free-wheeling diodes).
Suitable measures for protection against overvoltages are to be taken.
5.2 Installation and mounting PSC1 module
The module is only installed in switch cabinets that meet degree of protection IP54 as a
minimum.
The modules must be fastened vertically on a DIN rail
The ventilation slots must be kept adequately clear to ensure the circulation of air inside the
module.
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.
There is currently only one type of backplane bus connector:
PSC1-A-80-CON-TBUS-POWER:
Standard version (all contacts are available)
(Colour may differ from backplane bus connectors shown in 5.3.1)
Usage of the backplane bus connector PSC1-A-80-CON-TBUS-POWER:
The backplane connector PSC1-A-80-CON-TBUS-POWER can only be installed in
conjunction with expansion modules without a dedicated supply of power. It is not possible to
connect several standalone modules.
