ELECTRICAL CONNECTIONS
The electrical power supply must be in compliance with IEC 64-8
standard.
For the purposes of specifying components, remember that the
maximum power consumption figures indicated in the electrical
specifications table represent the maximum power draw during
operation.
Connection to the electricity mains must be fixed and include an earth
connection. It is also necessary to make the connection through a
differential switch with ≤ 30mA switch threshold, fitted outside the zones
0, 1, and 2 (IEC 64-8/7). The product must be connected to the
equipotential assembly using the relevant terminal (
base of the Spa-pack.

Make the power connection to the electrical panel using a 5-way cable
of specifications suitable for the application, which must be secured with
the PG 29 clamp provided on the panel for the purpose.
The connection must be made utilizing the terminals of the isolating
switch and the earth bar located internally of the panel (fig.13).
Thereafter, make the power connection to the underwater light (12V-2A),
which requires a two-core cable (not supplied). Specification: 2 x 1.5
H05VV-F.
Connect the wires to the panel using terminals 12 and 13, securing the
cable with the PG 13.5 clamp provided, and to the light fitting by way of
the relative terminal strip (fig. 13).
The underwater light must also be earthed, using a suitable green-
yellow wire (not supplied) of which the two ends are connected
respectively to the earth bar internally of the panel (PG 7 clamp
available), and to the screw on the body of the fitting (fig.13).
Secure both ends of the earth wire using suitable crimp terminals and
lockwashers.
Use the equipotential bonding terminal provided on the baseplate of the
Spa-pack to connect the equipment to the earth system of the building.

The buttons controlling the whirlpool Pump 1 and Pump 2 functions and
the underwater light are supplied with approximately 2000 mm of cable.
The Pump 1 button, identified by the label with the number 1 stamped
on the cable, is connected to terminals 14 and 18 (non-polar
connection).
Similarly, the Pump 2 button, identified by the number "2", and the
underwater light switch button numbered "3", are connected respectively
to terminals 15 and 19 and to terminals 16 and 20.
In the event of the cables being too short, the contractor can remedy the
situation with extensions, making certain that the connections meet
protection category IPX5 and using double insulated two-core cables of
section at least equal to that of the cable supplied with the buttons.
The underwater light and whirlpool buttons are mounted to a plate of
acrylic material with screw holes positioned to match a standard 4-gang
back-box or pattress made by any electrical hardware manufacturer.
The cables can be chased into the masonry along the selected route, by
the contractor.
Since the three buttons are completely watertight, any other type of
installation can be adopted by the contractor, on any surface.
The overflow tank must be fitted with the 3 level sensors (see fig.15),
which are supplied prewired to the electrical panel: the lowest of the
three, identified by lead number "4", is the minimum level indicator; the
middle sensor, identified by lead number "5", indicates the level that
should register permanently in the overflow tank, whilst the function of
the third sensor, uppermost and identified by wire number "6", is to
activate the filtration system whenever water is displaced from the pool
to the tank as the result of a bather stepping in.
Do not on any account alter the respective positioning of the level
sensors.
The leads "4", "5" and "6" cannot be extended, as this could cause the
system to malfunction. When preparing the layout, make certain the
Spa-pack and overflow tank are separated by a distance such that the
sensor leads will be long enough.
