• To avoid electro-magnetic interferences, power connection and sensors connections will be
isolated. Also avoid using diversion box.
• Connectors will be of electrolitic quality brass (no corrosion of denuded ends at connection
points).
• Never use telephone wire (cross-section of sub-connectors too thin and easy breakable at
connections points).
• Cross-section of connectors must be between 0,5 and 1mm².
