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 Universal Run / Stop switch is
correctly wired as per these instructions and wiring schematics. Incorrect wiring may lead to a short
circuit being placed across the batteries which can lead to fire or explosion.
Please use common sense when installing and operating your turbine and associated equipment.
Installation
Please refer to electrical schematic for appropriate generic wiring diagrams. If the cables you are
using don’t easily fit into the run / stop switch terminals, the cable can be reduced to 4mm2 or
2.5mm2 before entering the run / stop switch. The cable can then be increased again to its
previous size after the switch and this will have a negligible effect on volt drop.
The Universal 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.
Switch Wiring for LE-450 Turbine – please ensure all 12 screw terminals of the switch are screwed
closed before finally placing the top cover on the switch:
