connected to the remote switch input. For PSk3-7
to PSk3-15 refer to "Figure 7: Sensor terminal wiring
example" en la página 30.
Manual remote control switch – The oat switch
circuit can be used with a manual switch to turn the
pump on and o from a distance. Use any simple
on/o switch available from an electronic supply,
electrical supply, or hardware store (it only carries
low voltage, very low current).

9.8 Sacrical Anode
The LORENTZ Sacricial Anode is designed for use
with LORENTZ pump ends. Where solar pump ends
operate in aggressive water conditions acidic water
can attack the passive layer of the high quality-steel
pump end. This corrosion reduces the life-time of the
product. The LORENTZ Sacricial Anode contributes
to the protection of the pump system from this type
of corrosion and extends the pumps life.
For further information about the Sacricial Anode
please refer to the COMPASS datasheet.
9.9 PV Disconnect 1000-40-5
The LORENTZ PV Disconnect is a PV connection box
with an integrated disconnect switch. The box is
designed to connect up to ve PV module strings
with the pump controller by using the terminal
clamps located inside the box. The DC-rated
disconnect switch is used as a manual circuit breaker
between the solar array and the load. This switch
is easily accessible by opening the hinged lid at the
bottom spring lock.
The use of a properly sized DC disconnect switch is
an important safety measure and obligatory for a
professional installation of a solar pumping system.
The switch must be installed between the solar
generator and the pump controller. It must meet the
electrical requirements of the connected devices.
The PV Disconnect has been designed to cover the
range of PSk3 pump systems.
For more information on installing, wiring and
technical specications please refer to the PV
Disconnect manual.
