NOTE! The nodes are always located close to the components they control. A power train node, the Power train Control Unit (PCU), is located in the engine room. A helm node, the Helm station Control Unit (HCU), is located close to the helm station. Cables and connectors must never be located where they are exposed to water. Locate the electrical equipment far from heat sources. Choose cable lengths to minimize the number of connectors and never locate a connection in a non accessible area.
NOTE! You are not allowed to build network in a way that branches will be formed. Bus cables with branches longer than 0.5 m (1.6 ft) cannot exist in an EVC system. Also please refer to the Building a network. Requirements chapter for more information. IMPORTANT! Always make sure that the locking mechanism between the male and female connectors closes with a click. This guarantees a water-tight correct closure. IMPORTANT! Only use grease on gear shift solenoid and power supply connections. Other connections should not be greased.
