Installation After Transfer Box for
Protection from both Generator and AC Power.
For installation, in addition to the EMS Kit, you will need:
• 6 mounting screws
• In some cases you will need a jumper cable, length to be
determined based on the placement of the EMS
• Always use #6 wire.
1. Unplug RV from the AC power and be sure generator is off.
2. Locate transfer switch box; determine where the EMS control box
will be mounted.
3. Measure the distance between the transfer switch and the control
box and add one (1) foot. This is the length of cable that will be
required for the installation. Make sure 6-gauge, 4-conductor
cables are used.
4. Remove lid from transfer box, disconnect and remove the output
cable.
5. Take jumper cable and strip back one end three (3) inches, and the
other end the same as the end removed from the transfer box. The
cable removed from the transfer box must have at least three (3)
inches of the outer insulation removed. (See Picture A)
