Orion-Tr Smart DC-DC Charger Non-Isolated The use of ferrules is not required for cables from the above table. If an even thinner cable is used, a ferrule can help to bundle the loose wires. However, it is up to the installer to make sure that the cable is properly secured. With or without a ferrule, the connecting cable must be adequately clamped to ensure low contact resistance. Preparation for correct mounting of fine strand wires in the screw terminal block 1. Cut the cable straight with no loose or staggered threads. Using a wire cutter will result in a straight cut. 2. Make sure no fine wires are cut when stripping the insulation. 3.
Open the screw on the screw terminal block completely to prevent fine wires from getting caught behind the screw and bunching up. Pay particular attention to this when using the maximum wire diameter. 4. Tighten the screw with the correct torque; see Recommended torque [6] and note the wire size and wire class. Never apply less than the recommended torque. 5. Hold the recommended torque for at least 5 seconds, this will give the screw time to settle to the set torque. This maximises the force on the wire, thereby maintaining a gas-tight contact pattern during heating and cooling cycles over time. Take the time to do it right. This is important.
This is a UL486 test requirement and a requirement for all factory and field installations.
