range of actuators.
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
have to be used. Using interior telecommunications
wiring or comparable control wiring is recommen-
ded. Make sure however, that the wires of the load
and the control side are separated conforming with
VDE regulations within the sub-distribution. Keep a
minimum spacing of 8 mm between the two types
of wiring.
When connecting the RS485 bus, the A terminals
(1.3), the B terminals (1.7), the 24 V power supply
and the ground terminal (1.8) of the modules of
a sub-distribution (max. 127 segments) are to be
connected with one another. A connection diagram
with bus system is provided in the system manual.
When using several modules, a bus termination is
required. Information on the connections is provided
in the respective operating instructions.
