2.產(chǎn) 品 詳 情 資 料：
WOODWARD 5466-315保護接地（PE）始終在連接至115/230 V交流電源的設(shè)備上安裝保護接地連接。出于電氣安全的原因，所有導(dǎo)電部件（如DIN導(dǎo)軌或?qū)к壒潭ǖ膶?dǎo)電部件）都需要連接到PE。需要這種PE連接的安全原因是，例如，機柜內(nèi)布線僅提供基本絕緣，或意外接觸/連接（如松脫電線）導(dǎo)電金屬部件的危險電壓。該連接應(yīng)滿足IEC61131-2中PE連接的要求，即：靜態(tài)電流為30 A的導(dǎo)體，WOODWARD 5466-315測量的壓降對應(yīng)于<0.1歐姆。ABB強烈建議，如果是銅導(dǎo)線，設(shè)備PE導(dǎo)線的橫截面應(yīng)為35 mm2（2 AWG）。熔斷外部電源電纜標準AC 800M控制器配置的外部電源的推薦熔斷器額定值，安裝在地板或壁裝柜內(nèi)，WOODWARD 5466-315
Protective Earth (PE) Always install a protective earth connection on equipment connected to a 115/230 V AC supply. For electrical safety reasons all conductive parts, such as the DIN-rail or the conductive parts to which the rail is fastened, are required to be connected to PE. The safety aspect that requires such a PE-connection is due to e.g. in-cabinet wiring providing basic insulation only or accidental touch/connection (e.g. loose wires) of hazardous voltages to conductive metal parts. The connection shall fulfill the requirements in IEC61131-2 for PE connections, that is: A conductor which, having a static current of 30 A flowing through, measures a voltage drop which corresponds to <0.1 ohm. ABB strongly recommends that the equipment PE-conductor should be of 35 mm2 (2 AWG) cross section if copper lead.Fusing the External Mains Supply Cable The recommended fuse rating for the external mains supply of a standard AC 800M Controller configuration, housed within a floor or wall-mounted cabinet,WOODWARD 5466-315
