Bom manual de uso

As regras impõem ao revendedor a obrigação de fornecer ao comprador o manual com o produto Cooper Lighting M-LIB3. A falta de manual ou informações incorretas fornecidas ao consumidor são a base de uma queixa por não conformidade do produto com o contrato. De acordo com a lei, pode anexar o manual em uma outra forma de que em papel, o que é frequentemente utilizado, anexando uma forma gráfica ou manual electrónicoCooper Lighting M-LIB3 vídeos instrutivos para os usuários. A condição é uma forma legível e compreensível.

O que é a instrução?

A palavra vem do latim "Instructio" ou instruir. Portanto, no manual Cooper Lighting M-LIB3 você pode encontrar uma descrição das fases do processo. O objetivo do manual é instruir, facilitar o arranque, a utilização do equipamento ou a execução de determinadas tarefas. O manual é uma coleção de informações sobre o objeto / serviço, um guia.

Infelizmente, pequenos usuários tomam o tempo para ler o manual Cooper Lighting M-LIB3, e um bom manual não só permite conhecer uma série de funcionalidades adicionais do dispositivo, mas evita a formação da maioria das falhas.

Então, o que deve conter o manual perfeito?

Primeiro, o manual Cooper Lighting M-LIB3 deve conte:
- dados técnicos do dispositivo Cooper Lighting M-LIB3
- nome do fabricante e ano de fabricação do dispositivo Cooper Lighting M-LIB3
- instruções de utilização, regulação e manutenção do dispositivo Cooper Lighting M-LIB3
- sinais de segurança e certificados que comprovam a conformidade com as normas pertinentes

Por que você não ler manuais?

Normalmente, isso é devido à falta de tempo e à certeza quanto à funcionalidade específica do dispositivo adquirido. Infelizmente, a mesma ligação e o arranque Cooper Lighting M-LIB3 não são suficientes. O manual contém uma série de orientações sobre funcionalidades específicas, a segurança, os métodos de manutenção (mesmo sobre produtos que devem ser usados), possíveis defeitos Cooper Lighting M-LIB3 e formas de resolver problemas comuns durante o uso. No final, no manual podemos encontrar as coordenadas do serviço Cooper Lighting na ausência da eficácia das soluções propostas. Atualmente, muito apreciados são manuais na forma de animações interessantes e vídeos de instrução que de uma forma melhor do que o o folheto falam ao usuário. Este tipo de manual é a chance que o usuário percorrer todo o vídeo instrutivo, sem ignorar especificações e descrições técnicas complicadas Cooper Lighting M-LIB3, como para a versão papel.

Por que ler manuais?

Primeiro de tudo, contem a resposta sobre a construção, as possibilidades do dispositivo Cooper Lighting M-LIB3, uso dos acessórios individuais e uma gama de informações para desfrutar plenamente todos os recursos e facilidades.

Após a compra bem sucedida de um equipamento / dispositivo, é bom ter um momento para se familiarizar com cada parte do manual Cooper Lighting M-LIB3. Atualmente, são cuidadosamente preparados e traduzidos para sejam não só compreensíveis para os usuários, mas para cumprir a sua função básica de informação

    M-LIB3 Low Impedance Bus Differential Relay 22 6.1 GENERAL CHARACTERISTIC Currents from the CTs of the Feeders connected to each protected zone are conveyed to a wiring bus (one for each phase) that drives the positive and negative halfwave of the current on two different wires. The wiring bus also carries the signal from the CT ’ s saturation de[...]
