DANGER
During the entire period in which the device is powered, regardless of whether it is operated or
remains in stand-by (digital shutdown), high voltage is present inside the device and at the input and
output terminals.
DANGER
The device, previously in stand-by condition, may suddenly start up following the reset of an alarm
or changed system conditions. This may result in serious mechanical and electrical danger to the
operator who, upon seeing the device stopped, may have intervened on it, on the load or on the
system in which it is installed.
DANGER
Disconnect the device from the power supply, check that the load is completely stopped and wait at
least 15 minutes before intervening on it or on the load applied to it.
DANGER
If the motor is of the permanent magnet type, the device may be energized by the passive rotation of
the motor. In this case, both the power supply and the load should be disconnected before working
on the device itself.
DANGER
Ensure that the device is fully closed and all fixing screws are properly tightened before supplying
power. Do not remove the protective parts for any reason while the device is powered on.
DANGER
It is recommended to install the appropriate protection devices upstream of the device, such as a
circuit breakers, fuses and a residual current device (RCD).
DANGER
Make sure that the device and the loads connected to it are properly grounded with the appropriate
connection terminals before commissioning.
Ensure that the grounding system is compliant and refer to local regulations for grounding devices.
Each load must be fitted with its own earthing cable, the length of which must be as short as
possible. Do not make interconnected grounding connections.
Leakage currents may exceed 3.5 mA. It is recommended to use the reinforced ground connection if
necessary.
CAUTION
During operation, some surfaces may reach high temperatures that may cause burns upon contact
with skin. Be very careful when touching the device!
Avoid contact with flammable products.
WARNING
Do not start the pump for any reason unless it is completely filled with water.
Failure to do so may cause serious damage to the pump and the warranty will be void.
WARNING
During operation the pump produces a strong suction action that may trap people (especially chil-
dren) causing severe physical injury or even death. To reduce these risks, it is recommended to
install the pump and the system according to local regulations and check the correct functioning of
the grids that protect the suction points.
DANGER
Pay attention as the photovoltaic panels exposed to sunlight supply a DC voltage to any connected
devices.
