If the device is used in swimming pools, fountains or garden ponds, an automatic type "A" residual
current operated circuit breaker (with I∆n=30mA) must always be fitted.
The system comprising the Press•o•Matic and a motor pump is considered a "fixed system"; it is
therefore advisable to make arrangements to prevent the device being disconnected from the power line it
was originally connected to and mistakenly reconnected to another source of power not equipped with the
electrical protection required.
If the device is not fitted with a power lead and plug, to disconnect it from the mains install an omnipolar
cut-off device with a gap of at least 3 mm between the contacts.
To make the electrical connection, remove the green bipolar terminal marked "LINE" and connect the

The recommended wire section is 1.5mm2, which is compatible with motor pumps up to 1.1 kW. For
powers over 1.1 kW and up to 2.2 kW a 2.5mm
If the power lead is longer than 5-10 metres, a lead with a 2.5mm2 section should be used to reduce drops
in the power supplied by the lead and to reduce the chance of the under-voltage protection being
triggered.
The type of wire must be selected according to the conditions of use (domestic, dry or wet, indoor or
outdoor installation).
All installation restrictions stated by the manufacturer of the motor pump to which the Press•o•Matic is
connected must also be observed.
The device has a single-phase 230 Volt 50/60Hz power
line.
The electrical system to which the equipment is connected
must comply with the safety regulations in force and must
therefore be equipped with:
- an automatic magnetothermal switch with high breaking
capacity and with a trigger current proportional to the
capacity of the pump installed (see chart below)
- earthing with total resistance in conformity with local
standards and in any case never over 100Ω.
Warning: the pump must not be used when people are in
the water!

then fit the terminal back onto its seat and
proceed by attaching the earth wire to one
end of the earth faston. The faston terminals
must be crimped by specially trained
personnel, using proper crimping pliers.
