这些条款好像跟NFPA20的基本一致：
10.5.3.2* Emergency-Run Mechanical Control at Controller. 控制柜上的紧急运行机械控制
10.5.3.2.1 The controller shall be equipped with an emergency run handle or lever that operates to mechanically close the motor-circuit switching mechanism. 控制柜应配备一个紧急运行手柄或操作杆，用来采用机械手段闭合电动机回路的开关机构。
10.5.3.2.1.1 This handle or lever shall provide for nonautomatic continuous running operation of the motor(s), independent of any electric control circuits, magnets, or equivalent devices and independent of the pressure-activated control switch. 这个操作手柄或操作杆使电动机非自动连续运行，与任何电气控制电路、电磁机构或类似的装置无关，并且与压力开关无关。
10.5.3.2.1.2 Means shall be incorporated for mechanically latching or holding the handle or lever for manual operation in the actuated position. 应具备措施，将手柄或操作杆采用机械方法手动锁定在动作位置。
10.5.3.2.1.3 The mechanical latching shall not be automatic, but at the option of the operator. 机械锁定装置不得自动动作，而是有操作人员选定动作。
10.5.3.2.2 The handle or lever shall be arranged to move in one direction only from the off position to the final position. 手柄或操作杆只能以一个方向从断开位置向最终的闭合位置运动。
10.5.3.2.3 The motor starter shall return automatically to the off position in case the operator releases the starter handle or lever in any position but the full running position除在运行位置外，操作者在其他任何位置松开该手柄或操作杆，该电机起动器均应自动回到停止位置。
