5.2 ELECTRICAL PROTECTION

The installation on the fixed wiring of an electrical connection/disconnection, protection and
switching system which includes all necessary and recommended elements is compulsory. The
system must be equipped with:
A disconnecting circuit breaker that guarantees omnipolar disconnection, directly connected to the
power supply terminals and with contact separation on all of its poles, providing total disconnection
in overvoltage category III conditions.
Short-circuit and overload protection devices on motors.
Power supply via a residual current device (RCD) (differential switch), which has an assigned
operating current not exceeding 30 mA.
The unit must not be operated without additional protection (i.e. motor protection relay).
The characteristics and settings of such devices must be suitable for the equipment to be
protected and the expected operating conditions. The manufacturer's instructions must be followed
at all times (see rating plate).
See section 10. "TABLE OF CONDUCTORS AND CIRCUIT

5.3 ELECTRICAL CONNECTION

GROUND CONNECTION.
The earthed apparatus must be permanently connected to the fixed electrical installation.
All exposed non-live metal parts of the unit that may accidentally become live must be electrically
connected to the mains earthing conductor and to the earth connection of the pool structure, in
accordance with the specification of the applicable National or Local Electrical Code. Use a copper
conductor with a minimum section of 2,5mm² or AWG 13.
POWER SUPPLY.
DIN Standard
4844-W8
Never connect the power supply using the factory testing cables.
The unit must be permanently connected to the fixed electrical installation.
Ensure that no other equipment is connected to the same circuit.
The types and sections of power cables must comply with the specifications of the applicable Loca
or National Electrical Code.
withstand at least the current absorbed by the unit (see nameplate). Cables must be connected to
the unit's terminals blocks using the appropriate terminals.
The conductors must enter and exit the unit's connection box through a cable gland, providing a
watertight seal to prevent the ingress of water and dirt.
On three phase units, care must be taken to correctly position the motor winding connections.
(see fig. 4, 5).
Check the motor rotation direction before connecting the pump to the installation and before
making the final connection to the mains power supply.
To change the rotation direction on three-phase motors, swap the position of two of the motor's
power supply cables.
This unit is supplied with power cables used for factory testing

connected to its connection terminals. These cables must be
removed in order to connect the power supply.
