ELECTRICAL INSTALLATION
Cables:
The Aquair 100 is fitted with 5m of 1.5sq mm cable. Having sited the Aquair 100 on the boat,
measure the cable run distance to the batteries. If this distance is less than 10 metres (20 metres 24v
systems), use 1.5sq mm (16 AWG) cable. If less than 20 metres (40 metres 24v systems), use 2.5sq
mm (14 AWG) cable. Use a similar type of cable to that on the Aquair. Always use tinned stranded
conductors.
Connectors:
To carry power from the Aquair to the wiring on the boat we recommend that a quality
watertight connector be fitted. In the case of a wind and water combination, a watertight socket can be
fitted at each site. Alternatively, an extension cable with in-line connectors can be used for the wind
mode. The plugs and especially the sockets should have watertight caps when not in use.
Installation:
Wiring between the deck socket (or junction box, deck gland etc.) and the battery area
should be clipped at regular intervals to the structure for safety and a neat job
Protection:
The simplest possible arrangement feeds the power from the Aquair directly to the battery,
through an in-line fuse rated at 10 Amps (5 Amps 24v system) in the positive line next to the battery.
Figure 12. Basic Wiring
Wiring options:
In fig. 12, two optional components have been added to show where they might be
wired in the circuit.
o
The switch, which may be used as a simple means of charge control, should be rated at
15 Amps DC to ensure long life.
o
The ammeter is wired in series (assuming it to be of the internal shunt variety) in one
line. This allows the machine output to be seen at all times. As shown, the positive (+)
connection of the ammeter is made to the generator, whilst the negative (-) is made to
the battery.
Never connect an ammeter across the supply.
CAUTION:
IT IS MOST IMPORTANT TO FIT A FUSE
. The fuse should be next to the battery
terminal since, in the event of a fault or damage to the cable, the battery will supply a
large fault-current.
CAUTION:
When wiring the system be aware that if the Aquair is connected to the battery with
REVERSE POLARITY the output rectifiers can be destroyed.
Check and double-check
polarity before final connection.
CABLE COLOURS
: Core 1 (formerly BROWN) = + Positive
Core 2 (formerly BLUE) = - Negative.
CAUTION:
The Aquair generator output
MUST GO STRAIGHT TO THE BATTERIES
. If the Aquair
is connected on the DOWNSTREAM (load-side) of the battery isolator switch, it leaves
scope for damage to electrical equipment on the boat. Under these conditions it is
possible to run the Aquair whilst the battery is isolated. This can subject the system to
excess voltage.
Core 1 = +
