Chapter VII.
Installation
Section 7.01
Introduction
The panel and the other components may be physically installed with a distance of
theoretically up to hundreds of meters. However , we recommend that all output
modules and the master controller are physically located near each other.
All systems are custom made. Refer to drawings for the specific s ystem for
connection diagram.
General block diagram.
Section 7.02
Power cables to modules
All modules should be powered from the same 24VDC supply which comes from the
Master CPU. All modules have dual terminals, so they may be terminated in a daisy
chain from module to module.
Use minimum 0.5 mm² wires.
Section 7.03
Communication cables to modules
All modules should be connected to the same network cables which starts at the Master
CPU and ends up in the panel. All modules have dual terminals, so they may be
terminated in a daisy chain from module to module.
Communication cable should be a twisted pair, 100 - 250 Ohm characteristic impedance
(Cat. 5 is ok). The cable should also provide wires for a common reference a nd shield.
Never use a end-of line resistor in the network. The communication cable should not
be connected in a loop; it should always be end to end .
Each module has been factory set with correct node addresses and labeled
accordingly. Do not make any changes.
