Excel 500/600 Housing Layout (not XCL5010)
A controller comprises from one to a maximum of five
housings. The housings may be fitted alongside one another
or, one above the other. Any combination is possible.
Fig. 3. Up to five housings can be connected together
When housings are alongside one another, a minimum
spacing of 1.5 in. (35 mm) should be taken into consideration
to enable the hinged cover to be opened. The maximum
spacing between housings is limited by tailor-made internal
bus cables as shown in Fig. 3.
Excel 500/600 Internal Bus Wiring (not
XCL5010)
Each housing has four plug-in module locations. The
individual modules are connected by an internal bus in the
housing.
Configurations comprising more than one housing must have
the individual busses in the housings connected to one
another.
