230 V/12 V mains version
The power supply of the mains version is via a transformer
which converts  V AC to  V DC (order no. ,
order separately).
The electronics have one connection to the transformer
(connector with white marking) and one to an electronic
cartridge (connector with black marking). The third cable is
to earth the electronics onto the flush valve's brass hous-
ing.
Urinal electronics, 230 V/12 V mains version
Up to five urinal electronic units can be powered at the
same time by the transformer. For this reason, the trans-
former is not (!) located in the flush valve's bare-wall
protection system. The transformer fits conveniently in a
standard flush-mounted installation box.
For series installations, the electronics must be connected
in parallel and the connection cable between the trans-
former and the furthest electronic unit can be a maximum
of  m long.

It is recommended that only TECE original products are
used for the installation. Make sure that the polarity is cor-
rect when connecting the cables.
