ons and cable passages
1.1.1 Electric box power supply
Fig. 1
- Prepare a 230 V power supply using an R2V 3G2.5 mm²
(or Ro2V 3G2.5 mm²) cable for the electric box, which
must be installed outside the volumes,
0
,
1
and
2
,
and in a dry place (technical room).
1.1.2 Electrical
protec
ti
on
- The power supply must be protected by a circuit breaker
or a 10 A fuse holder and a 30 mA ground fault circuit
breaker.
1.1.3 Sheaths and cable passages
- Prepare a connection protected by a sheath for
the 24 V DC power supply between the electric
box and the box located by the roller using
2 x 6 mm² if the cable is less than 15 m and
2 x 10 mm² if the cable is between 15 m and 30 m long.
- Prepare a connec
ti
on protected by a sheath for the end
of run stop management between the electric box and
the box located close to the roller using 5 x 1.5 mm².
- Prepare a connec
ti
on protected by a sheath for the
control between the electric box and the switch using
3 x 1.5 mm².
- Separate cables carrying di
ff
erent voltages (24 V and
220 V) by passing them through di
ff
erent sheaths which
are spaced in compliance with NF C 15-100.
1.2 Building

1.2.1 Concrete
belt

- Plan a concrete belt using a 350 Kg cement per m
3
concrete mix with a size of w 40 cm x h 50 cm x l 150 cm
using at least 0.30 m
3
to stabilise the
fi
xture of the roller.
Consult the current electric standards and in par
ti
cular
NF C 15-100.

- Plan to control the water level at 12 cm below the edge
using a ø 50 mm over
fl
ow which is independent of the
skimmers and automa
ti
c
fi
lling. Take into account that
when the cover is rolled-in it will raise the water level
by 10 mm.
