1. Connect to Shore Power

• Plug the trailer into a 120V shore power source.

• The surge protector will automatically turn on when power is connected.

2. Check the Display

• Look at the screen once it powers up.

• It will show:

  • Voltage

  • Amperage

  • Hertz

  • An error code (if any)

3. Understand the Error Code

• E0 = Normal operation (no issues)

• Other codes may indicate a problem:

  • E2 = Open ground fault

4. If You See an Open Ground (E2)

• Try these steps:

  • First option (recommended):

    • Unplug from the current outlet.

    • Try a different power outlet or pedestal.

  • If the error continues:

    • Do NOT try to fix the wiring yourself.

    • The issue is likely with the campground pedestal or home wiring.

    • Contact:

      • Campground staff, or

      • A licensed electrician

5. Generator Use (Special Case)

• Open ground errors are common when using a generator.

• This is usually due to how generators are grounded.

• To resolve it:

  • Use a neutral bond plug designed for your generator.

  • This typically clears the open ground fault.

6. Bypass Mode (Not Recommended)

• Only use this if absolutely necessary.

  • Locate the EMS switch.

  • Flip it to “Bypass” mode.

•  Important:

  • This disables surge protection and diagnostics.

  • Your trailer becomes unprotected from electrical issues.

7. Normal Operation Reminder

• Always ensure the EMS is in NORMAL mode before plugging in shore power.

• In normal mode, the system protects your trailer and checks power quality before sending electricity inside.
