Temperature at terminals
The terminals on all equipment shall be so placed, arranged and ventilated that any conductors or cables connected thereto will not be liable to be exposed to temperatures in excess of those permissible for the conductor material and the class of insulation of the conductors or cables, where such insulation is relied upon to prevent short-circuit or contact with material through which leakage may occur.
Where temperature conditions are such as will require the use of connecting cables of heat-resisting type, prominent marking shall be provided adjacent to the terminals to indicate the type of connecting cable necessary.
For terminals for the connection of supply flexible cords to portable equipment, the temperature rises, in general, shall not exceed 50°C (to allow the connection of flexible cords having maximum operating temperature of 75°C) except under the circumstances covered by Footnote h to Table 5.7, which allows a higher operating temperature.

在终端的温度在所有设备上的终端位置须、 安排和通风任何导体或电缆或其连接将不会容易暴露在温度超过所允许的导体材料和绝缘的导线或电缆，在依赖这种保温是防止短路或与材料通过的泄漏可能会发生接触的类。温度条件在哪里如需要使用连接电缆的耐热型，突出标记须毗邻终端来指示必要的连接电缆的类型。为便携式设备供应软电线连接终端，温度的升高，一般情况下，不得超过 50 ° C （要允许的最高操作温度为 75 ° C 的绝缘导线连接） 除了下涉及脚注 h 对表 5.7，它允许更高的情况下操作温度。

在终端的温度所有的终端设备应放在通风安排是这样，任何conductors或电缆和连接thereto将不完全是一种暴露在这些permissible超额的导体材料和绝缘的conductors一流大学或绝缘电缆，是她在哪里搜索，以防止短电路或联系材料这可能发生泄漏的通孔。在温度条件是，如要使用连接电缆需要的热量耐磨型，突出打标应提供相邻的终端连接到电缆必要的显示类型。为终端的供应柔性绳连接到便携设备，温度上升，一般不超过50°C，（让连接有柔性绳的最大操作温度可以在不被覆盖），除了到20 h表5.7，它允许较高的操作温度。
