Important Safety Information
HIGH VOLTAGE WARNING – Always turn off power at the main service panel before installing
CAUTION: The RVMS100S must be mounted in an area where it will not be exposed to water or the elements. Exposure of the RVMS100S soft start to water can cause failure of the control and is a risk for fire or other electrical safety hazards.
We recommend that installation of any soft start be done by a certified technician or licensed electrician. All installations are to be done in accordance with local, state, and national electrical codes.
