CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the pictured interfaces, leads and visible ends to review the low-voltage battery-side and maintenance connection.以图示接口、引线及可见端部结构为依据，确认低压电池侧与维护连接的设计要点。
Low-voltage battery and maintenance scope低压电池侧与维护范围
Connection requirements can be reviewed for a solar controller battery side, auxiliary-power accessory or maintenance equipment. Photovoltaic-string and starter-current circuits require separate design and validation.可围绕太阳能控制器电池侧、辅助电源附件或维护设备讨论连接要求。光伏串侧及启动机大电流回路需要独立设计与验证。
Red/black leads and circuit mapping红黑导线与回路对应
Match red/black lead identification to a complete circuit table and verify the actual polarity of both end interfaces rather than relying on appearance.将红黑导线标识与完整回路表对应，并核对两端接口的实际正负极，避免只凭外观判断极性。
Ring-terminal installation环形端子安装
Confirm ring bore, fasteners, contact surface and insulation termination together. Allow lead bends and service access after installation without transferring cable pull to the ring ends.端子孔径、紧固件、接触面和绝缘收口需配套确认。安装后预留引线弯曲和维护空间，避免端子承受线缆牵拉。
Visible inline fuse holder可见串联保险座
Review the pictured holder with the fuse, conductors and load, confirming protection location, component ratings and replacement access.图示保险座需与熔断器、导体和负载共同评审，确认保护位置、物料额定及更换空间。

APPLICATIONS连接的应用
Application directions应用方向
These directions concern low-voltage battery-side, auxiliary-supply and maintenance connections. Confirm actual equipment and interfaces; photovoltaic-string or starter-circuit suitability is not claimed.以下为低压电池侧、辅助供电与维护接入的项目方向。实际设备及接口需要确认，本示例不声明适用于光伏串侧或起动机回路。
Controller low-voltage battery side控制器低压电池侧
For the battery side of a solar controller, confirm the controller battery terminals, battery connections and protection requirements from equipment data. This direction concerns low-voltage battery connections; it does not establish a photovoltaic-string connection.太阳能控制器的电池侧接线需按控制器电池端、蓄电池端和保护要求确认。此方向讨论低压电池连接，不将图示接口作为光伏组件串侧接口使用。
Detachable battery-maintenance leads电池维护可拆引线
For detachable maintenance leads, define the equipment interface, polarity and operating duration. Confirm whether ring ends remain installed and whether the plug-in end needs a cover, then check access and handling during sampling.维护设备的可拆引线需要确认设备端接口、正负极和使用时长。环形端子是否长期固定、插接端是否需带盖，都应在安装要求与样品阶段明确。
DC accessory interface adaptation直流附件接口转接
Create a connection table from the input/output data of both devices for a DC accessory adapter. The XT60, SAE-style or barrel-interface form does not replace checks of polarity, permitted current, supply direction and circuit protection.接口转接应按两端设备输入输出资料建立回路表。XT60、SAE式接口或DC圆孔端的形状不能代替极性、允许电流、供电方向和保护配置确认。
Battery-side circuit protection电池侧回路保护
For a lead with a fuse holder, review the fuse, holder, conductors and equipment load as a complete circuit. Define protection-device location and service access; ratings depend on the approved components and electrical duty.带保险座的结构需要把熔断器、保险座、导体和设备负载作为整套回路评审。明确保护器件位置及维护空间，实际额定值以确认物料和项目工况为准。
Auxiliary-distribution installation辅助配电安装
Arrange fixing points, terminal contact surfaces, insulation coverage and routing from the equipment drawing for auxiliary distribution. Match ring bores to their fasteners as a set; cable outside diameter does not establish electrical capability.辅助配电的固定点、端子接触面、绝缘覆盖和引线路径应按设备图纸安排。环形端子孔径与紧固件需成套核对，不根据线缆外径推定使用能力。
Maintenance-lead sample checks维护引线样品检查
Check continuity, polarity, mating, fuse-holder access and behavior under the agreed electrical duty during sampling. Record the test limits and connected equipment; a connector that can mate does not by itself establish suitability for service.样品可按项目确认导通、极性、插合、保险座操作和约定电气负载下的表现。测试限值与接入设备应记录，不能只以连接器能插合判断可投入使用。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is this a photovoltaic-string cable?这类线可以直接用于光伏组件串侧吗？
This page concerns low-voltage battery-side and maintenance connections. Photovoltaic-string connectors, voltage, insulation and exposure require separate review; an SAE-style, XT60 or barrel-interface form does not establish those requirements.本页讨论低压电池侧与维护连接。光伏串侧的连接器、电压、绝缘及环境要求需独立评审，不能从 SAE、XT60 或DC圆孔端外观推定满足。
Can it be selected for a starter circuit?可以用于启动机回路吗？
Starter-current duty is outside the confirmed scope of this page. Supply the system, load and installation conditions for a separate starter-circuit design, component selection and validation.启动机大电流不在本页确认范围。需要起动回路时，应另行提供系统、负载及安装工况，独立设计、选料与验证。
Does mating alone establish equipment compatibility?接口能插合就能接入设备吗？
Verify the actual interface specification, polarity, supply direction, permitted load and protection. A fuse holder does not replace confirmation of the complete circuit rating and operating conditions.仍需核对接口实际规格、正负极、供电方向、允许负载及保护配置。带保险座也不能代替整套回路的额定和工况确认。
Define the battery-side or maintenance interface确认电池侧或维护设备的接口
Share controller or maintenance-equipment data, both interfaces, polarity, target voltage and load, length, terminations and protection for configuration and sample review.请提供控制器或维护设备资料、两端接口与极性、目标电压及负载、线长、端子和保护配置，以便开展选配和样品评审。
