Also this jumper must be removed and exrnal surge suppressors instald in installations with a Floating Neutral input pase see the following section Special Instructions for Floating Neutral IT Sysms lar in this apr. If you want Hipot st this supply overvoltage proction must be disabd during the st by removing the board strap. Reenab overvoltage proction afr sting by reinstalling the strap. a Jumper Strap Connects Overvoltage Proction Devices Frame Ground Screw s on Board Frame Ground Figure . Overvoltage Proction Devices and Jumper Strap Q apr Installation Special Installation Instructions for Floating Neutral IT Sysms When the AC input power supplies lisd below are instald in a sysm where the Neutral line is not referenced Proctive Earth Ground these special installation instructions must be followed prevent dage the power supply. ICPWRS or lar version ICPWRA or lar version Definition of Floating Neutral Sysms A Floating Neutral Sysm is a sysm of power distribution wiring where Neutral and Proctive Earth Ground are not tied gether by a negligib impedance. In Europe this is referred as an IT sysm see IEC. In a Floating Neutral Sysm voltages measured from input s proctive earth ground y exceed the Volts AC input voltage specified in the power supply specifications in apr in this . Examp of Floating Neutral Sysm L N PE This sysm must be instald using the special installation instructions on the following page. Sysms in whi one g of the power distribution wiring is tied Proctive Earth or a tap between two gs of the power distribution wiring is tied Proctive Earth are not Floating Neutral Sysms. Ex of NonFloating Neutral Sysm L N PE L NPE L PE L These nonfloating neutral sysms do not require these special installation instructions. Installation and Hardware August Q Use These Special Installation Instructions for Floating Neutral Sysms . The input power s should be d according the instructions in the AC Power Source Connections section of this apr. . The facry instald jumper between s and of the Power Supply must be removed if using one of the Power Supplies that have this feature. See the Overvoltage Proction Devices section of the Power Supplies apr for details. . Voltage surge proction devices su as MOVs MUST be instald between the following s: From L earth ground From L Neutral earth ground The voltage surge devices must be rad su that the sysm is procd from power line transients that exceed Line voltage + V +NPEX. The expression NPE refers the voltage pontial between neutral and Proctive Earth PE ground. For examp in a Volt AC sysm with neutral floating V above earth ground the transient proction should be rad at: V + V +V V Q apr Installation DC Power Source Connections DC Input Wiring ACDC and DCOnly Power Supplies DC Input power can range from VDC for the VDC supply VDC for the VDC supply or VDC for the VDC supply. All power supplies have DC input capabilities. The following connection infortion applies all of them: Connect the + and s from the power source the p s on the board + the p the second . Connect the third from the p sysm ground. + VDC All Supplies The botm two s are connecd the isolad volt DC that can be used
