5 General information about
installation/the bus system
5.1 General information about installation
The connections of the HMW components can
basically be divided into two groups: the load side
and the control side (24 V power supply, pushbutton
inputs, RS485 bus).
Due to its function, the surge protector only features
the control side.
On the control side, however, only non-hazardous
safety extra-low voltages are used. Since there is
electrical isolation between the load and control
sides in the module, no mains power capable wires
