4.3 Electrical installation
Electrical Hazard:
The connection to the electric power supply must be completed by an electrician possessing
the technical-professional requirements outlined in the current regulations.
4.3.1 Electrical requirements
• The local regulations in force overrule specified requirements listed below.
Electrical connection checklist
Check that the following requirements are met:
• The electrical leads are protected from high temperature, vibrations, and collisions.
• The current type and voltage of mains connection must correspond to the specifications
on the data plate on the pump.
• The supply power line is provided with:
– A disconnect switch with a contact gap of at least 0.12 in (3 mm) must be installed
between the electrical service panel and controller.
WARNING:
To reduce the risk of electric shock, install only on a circuit protected by a ground-fault circuit
interrupter (GFCI)
The electrical control panel checklist
NOTICE:
The electrical service panel must match the ratings of the electric pump. Inappropriate
combinations do not guarantee the protection of the unit.
Check that the following requirements are met:
• The electrical service panel must protect the converter and the pump against short
circuit. A time lag fuse or a circuit breaker (Type C model is suggested) can be used to
protect the pump. Use only time-delay fuses to protect the pump.
• The pump has built-in overload and thermal protection. No additional overload protection
is required.
Electrical Hazard:
Before starting work on the unit, make sure that the unit and the control panel are isolated
from the power supply and cannot be energized.
Grounding (earthing)
Electrical Hazard:
• Always connect the external protection conductor to the ground terminal before
attempting to make any other electrical connections.
• Connect all the electric accessories of the pump and the motor to the ground, making
sure that the connections are completed correctly.
• Check that the protection conductor (ground) is longer than the phase conductors; in
case of accidental disconnection of the power supply conductor, the protection conductor
(ground) must be the last one to detach itself from the terminal.
Use a cable with several strands to reduce electric noise.
