4.4.1
Ground
DANGER: Electrical hazard
Always connect the external protection conductor (ground) to the ground terminal before
attempting to make any other electrical connections.
DANGER: Electrical hazard
Connect the unit and any electric accessories to a socket with protection conductor (ground).
DANGER: Electrical hazard
Check that the external protection conductor (ground) is longer than the phase conductors; In
case of accidental disconnection of the unit from the phase conductors, the protection
conductor must be the last one to detach itself from the terminal.
DANGER: Electrical hazard
Install suitable systems for protection against indirect contact, in order to prevent lethal electric
shocks.
4.4.2
Guidelines for the electrical control panel
NOTICE:
The electric panel must match the ratings on the unit data plate. Improper combinations could
damage the motor.
Install an overload circuit breaker with C-type curve and Icn ≥ 4.5 kA, or other equivalent
device, to protect the system against overloads and short circuits.
The unit has software that protects the pump unit against overloads and short circuits, see also
on page 24.
4.4.3
Guidelines for electrical connection
1.
Use a 3G1-1.5 multi-core power supply cord.
2.
Check that:
•
The mains voltage and frequency match the specifications on the data plate
•
The power supply cord is protected from high temperatures, vibrations, collisions and
abrasions.
3.
Check that the power supply line is provided with:
•
A short circuit protection device of appropriate size
•
A mains disconnection device with contact opening distance ensuring complete
disconnection for overvoltage III category conditions
•
An RCCB earth leakage switch with tripping current ≤ 30 mA.
