Safety Precautions
Safety must always be your primary concern during the assembly, installation and operation of your
LE-v50 turbine and DL-300 charge controller. Always be aware of the risks involved with mechanical
and electrical installation work. If in doubt about any issue regarding your turbine system, please
seek further assistance before proceeding.
Mechanical Safety Hazards:
Whilst installing the DL-300 charge controller or when performing routine inspection or
maintenance, always stop the turbine by activating the stop switch.
Electrical Safety Hazards:
The LE-v50 generates rectified DC voltage and the DL-300 controller also operates at these voltages.
Even at these low voltages there are inherent risks. Caution should always be used when
connecting an LE-v50 turbine or DL-300 controller to the electrical system.
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 explode
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 or face. Always follow the manufacturer's safety instructions
when handling lead-acid batteries.
Please use common sense when installing and operating your turbine and DL-300 Charge Controller
