产品内容介绍
WOODWARD 5466-258离散输出模块
显示的预期寿命表中显示了工作小时数（使用寿命），并由内置电解电容器的预期寿命决定。预期寿命以工作小时数表示。预期寿命根据电容器制造商规范计算。该预测模型允许从装运日期算起最多15年。MTBF代表平均故障间隔时间，根据统计设备故障计算得出，表示设备的可靠性。它是装置故障可能性的统计表示，并不一定代表产品的寿命。说明：a）使用适当的铜电缆，其设计工作温度为：环境温度不超过45°C时为60°C，环境温度不低于60°C时，为75°C。b） 遵循国家安装规范和安装规定！c） 确保绞合线的所有绞线进入端子连接！d） 一个连接点中最多允许两根具有相同横截面的绞线（PE线除外）。e） 请勿在没有PE连接的情况下使用该装置。该电源适用于工业环境以及住宅、商业和轻工业环境，无任何限制。CE标志符合EMC指南89/336/EEC和93/68/EEC以及低压指令（LVD）73/23/EWG。此设备符合FCC第15部分规则。操作需要满足以下两个条件：（1）该设备可能不会造成有害干扰；（2）该设备必须接受任何接收到的干扰，包括可能导致意外操作的干扰。
安装和操作说明
设备内部的危险电压。有触电、严重烧伤或死亡的风险如果没有正确的接地连接（保护接地），请勿使用该装置。使用接线板上的插针进行接地连接，而不是使用外壳上的一个螺钉。•打开电源之前，请先关闭电源。防止意外重新通电。•遵循所有当地和国家规范，确保接线正确。•请勿打开、修改或维修装置。•小心防止任何异物进入外壳。•请勿在潮湿位置或可能出现湿气或冷凝的区域使用安装方向：输出端子必须位于顶部，输入端子必须位于底部。其他方向见第27.14节。冷却：对流冷却，无需强制冷却。不要覆盖通风格栅（例如电缆导管）超过30%！安装间隙：当永久满载时，建议顶部40mm，底部20mm，左右侧5mm。如果相邻设备是热源，建议间隙为15mm。维修零件：该装置不包含任何可维修零件。内部保险丝跳闸是由内部缺陷引起的。通常，负载电流不是恒定的。它随时间而变化。对于脉冲负载兼容性，必须满足以下规则：a）脉冲功率需求必须低于标称功率的150%。b） 脉冲功率的持续时间必须短于允许的功率提升时间。（见输出部分）c）平均（R.M.S.）输出电流必须低于规定的连续输出电流。如果R.M.S.电流较高，装置将在一段时间后响应热关机。使用最大占空比曲线（图27-2）检查平均输出电流是否低于标称电流。d） 对于高于2000m的高度，降低脉冲负载（15W/1000m）或环境温度（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)
