2.產(chǎn) 品 詳 情 資 料：
WOODWARD 5466-315大型分散工廠（如供水設(shè)施和煉油廠）的接地系統(tǒng)不足，信號(hào)電纜可能在地面上敷設(shè)。在這種情況下，必須安裝防雷設(shè)備。如果在接地系統(tǒng)外部發(fā)現(xiàn)電纜（即使距離較短，如10米[9.1碼]），則必須安裝防雷設(shè)備。電源在正常情況下，AC 800M控制器和相關(guān)現(xiàn)場(chǎng)設(shè)備所需的電源可從電廠的標(biāo)準(zhǔn)120/230 V AC電源獲得。電網(wǎng)濾波器使用WOODWARD 5466-315電源裝置時(shí)，無(wú)需使用電網(wǎng)濾波器。電源斷路器電源斷路器必須安裝在控制器裝置附近，以便在需要時(shí)立即斷開(kāi)設(shè)備的總電源。然而，電源斷路器的主要功能是在維護(hù)期間提供完全隔離電源的方法。電源斷路器必須安裝在易于接近且清晰可見(jiàn)的位置，即任何外殼或機(jī)柜外部。WOODWARD 5466-315
However, large dispersed plants such as water supply installations and oil refineries will have an inadequate grounding system where signal cables may be routed above ground. In such cases lightning protection equipment must be installed.WOODWARD 5466-315Should cables be discovered outside the grounding system (even at a short distance such as 10 m [9.1 yds]) lightning protection equipment must be installed.Power Supply Under normal circumstances, the power supply required by AC 800M Controller and associated field equipment can be obtained from the plant’s standard 120/230 V AC mains supply. Mains Net Filter It is not necessary to use mains net filters when using the WOODWARD 5466-315power supply units. Mains Breaker A mains breaker must be installed in the immediate vicinity of a controller installation to allow for immediate total power supply disconnection to the equipment, should the need arise. However, the prime function of the mains breaker is to provide a means of isolating the power supply completely during maintenance. The mains breaker must be installed in a location where it is both easily accessible and clearly visible, that is, outside any enclosure or cabinet.WOODWARD 5466-315
