Safety Precautions 

 
Safety must always be your primary concern during the assembly, installation and operation of your 

LE-v50

  turbine.  Always  be  aware  of  the  risks  involved  with  mechanical  and  electrical  installation 

work.  If  in  doubt  about  any  issue  regarding  your  turbine,  please  seek  further  assistance  before 
proceeding. Installation of the 

LE-v50

 turbine should only be undertaken by suitably competent and 

qualified personnel.  
 

Mechanical Safety Hazards 

 

The main rotor is the most obvious and serious mechanical safety risk. When the turbine is 
operating  at  its  rated  performance,  the  blades  may  be  very  difficult  to  see,  due  to  the 
speed of rotation. Never approach the turbine whilst it is operating at speed. 

Ensure that 

the turbine is installed in a suitable position where nobody can  interfere with the rotor 
blades.  

 

Working with tools of any kind can be dangerous. Your 

LE-v50

 turbine requires some basic 

mechanical assembly with rudimentary hand tools. If you are in any doubt about how to 
use these tools correctly, please seek advice from a suitably experienced person. 

 

Your 

LE-v50

  turbine  will  inevitably  be  installed  upon  a  mast  or  tower  or  other  support 

structure.  This  may  mean  working  at  height.  Always  ensure  that  all  personnel  in  the 
immediate  vicinity  are  aware  of  any  lifting  /  hoisting  operations  that  will  be  occurring. 
Check  there  are  no  loose  components  or  tools  likely  to  fall  and  cause  injury  during  the 
lifting operation. Where possible, all assembly work should be completed at ground level.  

 

Ensure that the batteries are disconnected during the installation procedure. 

 

Twist the turbine output cables together (to create a short circuit) during the mechanical 

installation process. This will prevent the turbine from ‘spinning up’ during the installation.

 

 

Never install the turbine upside down or in any orientation other than that depicted on the 
installation instructions. 

 

Install your turbine during a calm day. 

 

Electrical Safety Hazards 

 

The

 LE-v50

 generates rectified DC voltage. Even at these low voltages there are inherent 

risks. Caution should always be used when connecting the 

LE-v50

 to the electrical system. 

 

Ensure  that  you  have  followed  the  cable-sizing  chart  to  ensure  that  the  correct  size  of 
transmission cable has been selected. If a cable of insufficient cross-sectional area is used, 
heat may build up in the cables causing a potential fire hazard. Using cables of insufficient 
cross-sectional area may also reduce the power transmission efficiency of the turbine. 

 

Battery  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 can explode when shorted. Always 

use insulated electrical tools when working on the battery’s electri

cal 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 contac

t 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!
