What to do if my Hach SC4500 will not power up?

If the Hach Controller isn't powering up, ensure the power cable is securely connected to the controller and that all power connections are properly terminated. Verify that the power strip, line power, and wall plug are correctly plugged in. Also, confirm that the controller is connected to the appropriate power source: 100-240 VAC for AC controllers or 18-28 VDC for DC controllers.
