ligações de aterramento Explanation: Em PT-PT seria "ligações à terra de protecção". Esta tradução é consistente com a frase original "... as ligações de aterramento devem ser removias conforme indicado a seguir, na ordem seguinte" O termo "spider" indica que as ligações dos diversos elementos a proteger são efectuadas num único ponto. Os cabos de aterramento assim ligados (com uma "cabeça" e muitas "pernas") parecem-se com uma aranha. Daí o termo "earthing spider". Spider earthing A good earthing scheme in most cases is a 'Spider' earth. Chose one point in the machine and run each and every signal and power earth back separately to this one point. It is often convenient to have this 'spider' point as the chassis earth. It should (as we have seen) be close to the battery negative terminal of the main power control device as is possible, without being silly. Clearly this requirement can get a bit tricky when the machine in question uses many power controllers, but the spider earthing system is then really the only way to minimise problems. |
