DS40M Pump User Manual / 87-900-147-01(B) 89/112
NOTE
If you start a pump at low temperature, the current absorbed by the motors will
be for several seconds higher than the nominal one, for this reason the fuse or
the protection device on the line must be of the slow-blow type.
WARNING! If you use a mains cable with a length of 3 m max and a separable plug, it is
recommended to connect the pump to mains power through a dedicated
switch on the main electrical panel of the installation, or in proximity of the
power supply connection point.
In all other cases (cable length more than 3 m or permanently connection)
the pump must be connected to mains power through a dedicated switch in
the building installation.
