0 VDC operating voltage
Short circuits between Dupline signal conductors and the 24 V operating voltage or con-
nections to the grounding lead to malfunction and are not allowed. The correct polarity
of operating voltage and Dupline signal conductors has to be ensured.
In order to avoid malfunctions, the length of leads at the input side should not exceed
50 m with AC voltage, and 100 m with DC voltage. Because of rectification at the input
side, there is no need to check for correct polarity even when using DC voltages.
In order to meet the requirements for protective low voltage, VDE0100, Part 410, should
be observed and put into practice during installation. In cases of mixed operation with
AC voltage at one input and DC voltage at the other, the above requirements are not
fulfilled.
When connecting please observe that the maximum torque of the terminals of 0.6 Nm
will not be exceeded.
The patented click-and-lock-mechanism allows an easy removal of the unit from the rail
by pushing the housing upwards until it is released.
