Note:
When laying cables, safe isolation between different types of currents within an
installation system must be ensured
without exception
. Comply with the
requirements of DIN EN 50174 and DIN VDE 0100-520 for communication wir-
ing when laying the cables.
Safety isolation
For reasons of electrical safety, the sensor button must without exception be
operated via "safety isolation" such as a control box item no. 61405 or directly
on the NT switch box. The defined maximum line lengths must also be
observed.
The converter box 3.0 also serves as a
safety isolating element and for
evaluating button pulses of the sensor
button.
The signal output for the
XANAS
® is via an
analog output (AOUT).
The main task of the converter box is to
ensure a safe isolation between the sensor
buttons (buttons 1-3) on one side and the
analog and Vcc connections on the other
side of the frequency inverter. The purpose
of the converter box is to ensure safe and
reliable operation of the sensor buttons in the
swimming pool.
The converter box must always be positioned above the water level of the
pool!
