6.3 Wiring
6.3.1 Wiper system
This section describes how to connect the
housings equipped with glass wiper system
For these versions it is not necessary to mount
any component inside the casing since the units
are supplied complete with all the elements
necessary, according to the model requested.
• Connect terminal S of clamp J1,
to the mains power phase
• Connect terminal C of clamp J1, to
the mains power neutral.
• Connect terminal P of clamp J1, to a push-
button which in turn is connected to the
mains power phase, and allows the activation
of the wiper system by keeping it pressed.
By releasing the push-button the wiper
blade will return to the rest position.
Should a receiver with wiper command be
available, connect terminals SW, PER and COM
respectively to terminals S, P and C of clamp J1.

g In the 230Vac model it is necessary to
insert on the supply line, upstream of
the equipment, a unipolar 1 0 main
switch (distance of contacts opening
d>3 mm). This switch must be used as
circuit breaker to the power supply
before carrying out any maintenance
operation or opening of the equipment.
