3.2 ELECTRICAL CONNECTIONS

WARNING
Verify that the voltage and frequency of the electropump shown on the nameplate correspond to those available on the mains.
DANGER - ELECTRIC SHOCK RISK
The installer must make sure that the electric system is grounded in accordance with the law in force.
DANGER - ELECTRIC SHOCK RISK
Make sure that the electric system has a high-sensitivity circuit breaker ∆ = 30mA (Din VDE 0100T739).
Single-phase motors have a permanently inserted condenser and a thermal protection fitted on the motor winding. Customers
will be responsible for protections of three-phase motors. Electric connections should be performed using cables H07RN-F (for
external connections) or H05RN-F or H07RN-F (for internal connections).
