each country. Before doing manipulations inside the device,
it must be disconnected from the electric supply.
Wrong connection could spoil the electronic circuit.
The manufacturer declines all responsability in dama-
ges caused by wrong connections.
Check if power supply is beetween 110-230V.
If you have purchased the unit without cables follow dia-
gram B.
• Use cables type H07RN-F for power supply and motor
connection with section 3G1 or 3G1,5 depending on the
power installed.
• Do the pump connection U, V and
• Do the power supply connection L, N and
The earth conductor must be longer than the others.
It will be the first one to be mounted during the as-
sembly and the last one to be disconnected during the
dismantling.
Use cable H05VVV-F 4x0.5 for IN-OUT and COMMUNICA-
TION connection.
• Use IN connector for the external input.
• Use OUT connector for the alarm monitor.
• Use COMUNICATION connector to connect 2 DPR fo-
llowing the wiring diagram FIG. D.
Connect the IN-OUT wires of both DPR MASTER in parallel
inside of a junction box to connect the external input and
the alarm monitor to both devices.
The earth conductors connections are compulsory!
