5 Electrical Installation
5.1 Precautions
WARNING:

EQUIPMENT HAZARD. Rotating shafts and electrical equipment can be hazardous. All
electrical work must conform to national and local electrical codes. Installation, start-up, and
maintenance must be performed by trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
Electrical Hazard:

All electrical wiring must be carried out by an authorized electrician, in accordance with the
electrical regulations locally in force.
5.2 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 power supply line is provided with:

A high-sensitivity differential switch (30 mA) [residual current device RCD] suitable for earth
fault currents with DC or pulsating DC content (a Type B RCD is suggested).

A mains isolator switch with a contact gap of at least 3 mm.
The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the electric pump. Improper combinations could fail to
guarantee the protection of the unit.
Check that the following requirements are met:

The control panel must protect 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.

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 ground (earth) terminal before making other
electrical connections.
All electrical equipment must be ground (earth) connected. This applies to the pump unit and
related equipment. Verify the pump ground terminal is earthed.

Keep the ground wire connections as short as possible.

Use high-strand wire to reduce electrical noise is recommended.
