QUALIFIED PERSONNEL ONLY IN ACCORDANCE WITH LOCAL REGULATIONS.
Before to proceed, verify the following steps:
1. Verify the data on nameplate.
Make sure that the electrical data on the nameplate of the motor corresponds to the
electrical supply.
2. Verify the grounded power outlet.
The pump must be plugged to a grounded power outlet. Pump must be connected to a
motor protection switch (Residual Current Circuit Breaker - MCCB).
3. Install a relay switch. Do not install it in parallel with heavy inductance load (for
example: engines). See fig. 10.
