Installation Instructions for Pedestal/Shore Power
See next page for both Pedestal and Generator Protection
1. Unplug RV from the power source and be sure the generator is off.
2. Determine a location for the EMS control box. Keep in mind the input and output.
Make sure you will be able to view the digital display.
3. Cut the RV power cord about 3¼ inches greater than the distance from the junction
box to the desired location of the EMS control box. Then carefully remove 3¼
inches of the outer insulation on the input and output cables.
4. Strip back each conductor
⅜
inch on both input/output ends.
5. Remove control box cover. Back off the six set screws from the top of contactor

current sensor with the green tape on it. B) Insert the Red wire thru the other
current sensor. Make sure that the wire colors match across the relay from each
other.
8. Double check all connections and make sure they are secure.
9. Secure cable end by tightening down strain relief’s over outer jacket. Do not over
tighten this could bite through insulation and cause a short.
