Overload protection
The single phase motors are protected from overloads by a thermal device installed in the winding. The protection for
the three phase motor must be installed by the user.
Supply cables and extensions should have a section below that of H07 RN-F. The plug and connections should be
protected by water splashes.
For connecting single phase motors see Fig. 2

Instructions for a safe pump start
Avoid exposing the pump to humidity. Protect the pump from rain, making sure that there are no leaking fittings over the
pump. Avoid using the pump in wet or damp environments.
Make sure that the pump and the electric connections are protected from possible inundation.
Before using the pump, always inspect it visually (especially power cables and plugs). Do not use the pump if it is
damaged.
If the pump is damaged, have it inspected by the specialised assistance service only.
Do not transport the pump using the cable or use the cable to remove the plug from the socket. Protect the plug and the
power cables from heat, oil or sharp edges.

Verify that the voltage and frequency of the electropump shown on the nameplate
correspond to those available on the mains.
The installer must make sure that the electric system is grounded
in accordance with the law in force.
Make sure that the electric system has a high-sensitivity circuit
breaker
Use the electropump for the applications listed on the nameplate.
Do not operate the pump dry, since lack of water could cause it to overheat. In
this case, the water inside the system gets very hot, so there is a risk of
scalding. Take off the plug and let the system cool down.
Do not run the electropump with a completely closed delivery.
The power cable must be replaced by qualified personnel only.
