E 1. Always ensure the Earth conductor DOES NOT pass through the N N toroid. If it is unavoidable, the Earth must be routed back through 3 1 2 3 3 E the toroid again and around, as shown in Fig.2 below. 1 2 1 2 2. As a rule, select a toroid that has an inside diameter which is twice that or greater than the outsider diameter of the cable(s) to be passed through. 3. Ensure the cable is central in the toroid. 4. Place the toroid on a straight section of cable, not near a bend. 5. Keep the cable and toroid away from intense magnetic fields from nearby equipment. 6. DO NOT pass individual conductors through separate toroids, as shown Fig. 1 Fig.2 Fig.3 in Fig. 3.
