When two or more SPAU 341 C regulators are
operated in parallel, using the bus connection
modules SPA-ZC 100 as communication de-
vices, certain slave numbers have to be selected
for the regulating modules. The bus connection
modules SPA-ZC 100 can be ordered with fac-
tory configurations, adapted for these specific

If the regulators are to be connected to a sub-
station bus system, and the slave address codes
of the factory configuration interferes with the
previously selected codes, the bus connection
modules have to be reconfigured. During con-

regulators are working independently, without
being connected to a substation bus system. The
