5 General information on
bus system

5.1 General information on the installation

Basically, the connections of the HMW components
can be divided into two groups. In the load side and
in the control side (24 V power supply, button inputs,
RS485 Bus).
Load side
Since normally a 230 V consumer is on the load side,
using VDE-conforming installation wires, such as e.g.
NYM wiring, etc. is required. The wire cross-section
conform with the standard VDE regulations and is
1.5 mm2 for installations in the nominal load range of
actuators.
