This system must be installed using the special installation instructions on the following page. Systems in which one leg of the power distribution wiring is tied to Protective Earth or a tap between two legs of the power distribution wiring is tied to Protective Earth are not Floating Neutral Systems. Examples of Non-Floating Neutral System Use These Special Installation Instructions for Floating Neutral Systems 1. The input power terminals should be wired according to the instructions in the “AC Power Source Connections” section of this chapter. 2. The factory installed jumper between terminals 3 and 4 of the Power Supply module must be removed if using one of the Power Supplies that have this feature. See the “Overvoltage Protection Devices” section of the “Power Supplies” chapter for details. 3. Voltage surge protection devices, such as MOVs, MUST be installed between the following terminals: Ŷ From L1 to earth ground Ŷ From L2 (Neutral) to earth ground The voltage surge devices must be rated such that the system is protected from power line transients that exceed Line voltage + 100V +(N-PE)MAXABB INNPM11
