The speed controller is sturdy and durable enough to be installed in the control box or fixed on the peripheral parts of other control equipment on the engine. If water, moisture or condensed water enters into contact with the controller, it must be installed vertically so that the liquid can flow away from the speed controller;between/div>betweendiv>2. Prevent overheating: Drive at overspeed, not controlled by the speed control system to protect personnel and equipment from damage when the engine fails. Don't rely entirely on the electronic actuator of the speed control system for overspeed protection. You must use another set of parking drive, such as a fuel solenoid valve.between/div> Package List 1 x Engine Speed Regulator 1 x User Manual
