5.2. PROTECTION AND SIGNIFICANT CAUTION
All live wires or parts are electrically isolated
from the earth. However, there is an additional
safety feature, which composes of all accessible
conducting parts being connected to an earth wire
so that these parts cannot become hazardous
if the main isolating system fails.
5.3. RESIDUAL RISKS
A residual risk of entering into contact (even if
not accidentally) with the rotor in the suction
port exists due to pump construction.
The residual risk exists in models with thermal
motor protection, that once the trip has activated,
the pump may restart without notice once
the motor has cooled to within the required
operating temperature limits.
