WOODWARD 5466-258離散輸出模塊
顯示的預期壽命表中顯示了工作小時數（使用壽命），并由內置電解電容器的預期壽命決定。預期壽命以工作小時數表示。預期壽命根據電容器制造商規范計算。該預測模型允許從裝運日期算起最多15年。MTBF代表平均故障間隔時間，根據統計設備故障計算得出，表示設備的可靠性。它是裝置故障可能性的統計表示，并不一定代表產品的壽命。說明：a）使用適當的銅電纜，其設計工作溫度為：環境溫度不超過45°C時為60°C，環境溫度不低于60°C時，為75°C。b） 遵循國家安裝規范和安裝規定！c） 確保絞合線的所有絞線進入端子連接！d） 一個連接點中最多允許兩根具有相同橫截面的絞線（PE線除外）。e） 請勿在沒有PE連接的情況下使用該裝置。該電源適用于工業環境以及住宅、商業和輕工業環境，無任何限制。CE標志符合EMC指南89/336/EEC和93/68/EEC以及低壓指令（LVD）73/23/EWG。此設備符合FCC第15部分規則。操作需要滿足以下兩個條件：（1）該設備可能不會造成有害干擾；（2）該設備必須接受任何接收到的干擾，包括可能導致意外操作的干擾。
安裝和操作說明
設備內部的危險電壓。有觸電、嚴重燒傷或死亡的風險如果沒有正確的接地連接（保護接地），請勿使用該裝置。使用接線板上的插針進行接地連接，而不是使用外殼上的一個螺釘。?打開電源之前，請先關閉電源。防止意外重新通電。?遵循所有當地和國家規范，確保接線正確。?請勿打開、修改或維修裝置。?小心防止任何異物進入外殼。?請勿在潮濕位置或可能出現濕氣或冷凝的區域使用安裝方向：輸出端子必須位于頂部，輸入端子必須位于底部。其他方向見第27.14節。冷卻：對流冷卻，無需強制冷卻。不要覆蓋通風格柵（例如電纜導管）超過30%！安裝間隙：當永久滿載時，建議頂部40mm，底部20mm，左右側5mm。如果相鄰設備是熱源，建議間隙為15mm。維修零件：該裝置不包含任何可維修零件。內部保險絲跳閘是由內部缺陷引起的。通常，負載電流不是恒定的。它隨時間而變化。對于脈沖負載兼容性，必須滿足以下規則：a）脈沖功率需求必須低于標稱功率的150%。b） 脈沖功率的持續時間必須短于允許的功率提升時間。（見輸出部分）c）平均（R.M.S.）輸出電流必須低于規定的連續輸出電流。如果R.M.S.電流較高，裝置將在一段時間后響應熱關機。使用最大占空比曲線（圖27-2）檢查平均輸出電流是否低于標稱電流。d） 對于高于2000m的高度，降低脈沖負載（15W/1000m）或環境溫度（5°C/1000m）
The Lifetime expectancy shown
in the table indicates the operating hours (service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment. MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of the unit to fail and does not necessarily represent the life of a product.Instructions: a) Use appropriate copper cables that are designed for an operating temperature of: 60°C for ambient up to 45°C and 75°C for ambient up to 60°C minimum. b) Follow national installation codes and installation regulations! c) Ensure that all strands of a stranded wire enter the terminal connection! d) Up to two stranded wires with the same cross section are permitted in one connection point (except PE wire). e) Do not use the unit without PE connection The power supply is suitable for applications in industrial environment as well as in residential, commercial and light industry environment without any restrictions. CE mark is in conformance with EMC guideline 89/336/EEC and 93/68/EEC and the low-voltage directive (LVD) 73/23/EWG.This device complies with FCC Part 15 rules. Operation is subjected to following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
INSTALLATION AND OPERATION INSTRUCTIONS
Hazardous voltage inside device. Risk of electric shock, severe burns, or death. ? Do not use the unit without proper earth connection (Protective Earth). Use the pin on the terminal block for earth connection and not one of the screws on the housing. ? Turn power off before working on the power supply. Protect against inadvertent re-powering. ? Make sure the wiring is correct by following all local and national codes. ? Do not open, modify or repair the unit. ? Use caution to prevent any foreign objects from entering into the housing. ? Do not use in wet locations or in areas where moisture or condensation can be expected. ? Mounting Orientation: Output terminal must be located on top and input terminal on the bottom. For other orientations see section 27.14. Cooling: Convection cooled, no forced cooling required. Do not cover ventilation grid (e.g. cable conduits) by more than 30%! Installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended. Service parts: The unit does not contain any serviceable parts. The tripping of an internal fuse is caused by an internal defect.Typically, a load current is not constant. It varies over time. For pulse load compatibility, following rules must be met: a) The pulse power demand must be below 150% of the nominal power. b) The duration of the pulse power must be shorter than the allowed Power Boost Time. (see output section) c) The average (R.M.S.) output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit will respond with a thermal shut-down after a while. Use the max. duty cycle curve (Fig. 27-2) to check if the average output current is below the nominal current. d) For altitudes higher than 2000m reduce the pulse loading (15W/1000m) or the ambient temperature (5°C/1000m)
