10.8 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 five 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 PSk2 pump systems.
For more information on installing, wiring and technical
specifications please refer to the PV Disconnect manual.
