Safety Precautions
Safety must always be your primary concern during the assembly, installation and operation of your
turbine and other associated equipment. Always be aware of the risks involved with mechanical
and electrical installation work. If in doubt, please seek further assistance before proceeding.
Mechanical Safety Hazards:
Whilst installing the run/stop switch, ensure that the turbine is suitably restrained and not allowed
to operate during the installation.
Electrical Safety Hazards:
Our wind turbines generate rectified DC voltage and the run/stop switch also operates at these
voltages. Even at these low voltages there are inherent risks. Caution should always be used.
Ensure that you have followed the cable-sizing guidelines to ensure that the correct size of cable
has been selected. If a cable of insufficient cross-sectional area is used at any point in the electrical
system, heat will build up in the cables causing a potential fire hazard. A properly-sized fuse or
circuit breaker should be used in the cables connected to the battery. This will stop the risk of short
circuit currents.
Batteries used in renewable energy systems can deliver a serious amount of current. A short circuit
in the battery circuit can lead to hundreds of Amps flowing through the battery cables. This will
cause a heat build-up and ultimately an electrical fire. Batteries are also susceptible to exploding
when shorted. Always use insulated electrical tools when working on the battery’s electrical
connections.
Batteries are very heavy. Do not attempt to move batteries by yourself. Always use manual
handling tools and an assistant. Always keep lead-acid batteries the correct way up. Do not allow
the acidic electrolyte to spill or come into contact with your skin. Always follow the manufacturer’s
safety instructions when handling lead-acid batteries. Ensure that the run/stop switch is correctly
wired; incorrect wiring may lead to a short circuit across the batteries and lead to fire or explosion.
Installation
The Run / Stop Switch can either be mounted in the enclosure box (supplied), which, in turn, can be
mounted on an internal panel, or the switch can be integrated into an existing panel. If the unit is to
be integrated into an existing panel, a suitable cut-out, as detailed on the wiring diagram will need
to be made.
A shorting link needs to be added between pins 3 and 7, and pins 7 and 11.
Please ensure all 12 screw terminals of the switch are screwed closed before finally placing the
top cover on the switch:
