OPERATION & INSTALLATION
The MTS only switches the two hot wires coming from the generator; with this configuration the neutral wire
will always maintain contact between the generator and your main panel. Most portable generators have a
neutral ground bond for safe remote operation. In order to avoid an unsafe ground loop situation when using a
portable generator with this switch the generator should be converted to operate with a floating neutral. Making
this change should only be done by a licensed electrician. Consult your generator manual for details on this
procedure.

FUNCTIONAL TESTING
At the completion of the installation, test for proper operation;
1. Attach the portable generator to the MTS through the inlet.
2. Turn off all sub panel circuit breakers and the utility circuit breaker.
3. Start the backup Generator.
• Turn on circuit breaker A2 and verify that the lower left and the upper right LED’s are illuminated. If the
LED’s are not illuminated verify that the circuit has a load attached to the circuit.
• Turn on circuit breaker B2 and verify that the lower right LED is illuminated. If the LED is not illuminated
verify that the circuit has a load attached to the circuit.
• Turn on circuit breaker A3 and verify that the middle left LED’s are illuminated. If the LED’s are not
illuminated verify that the circuit has a load attached to the circuit.
• Turn on circuit breaker B3 on and verify that the middle right LED’s are illuminated. If the LED’s are not
illuminated verify that the circuit has a load attached to the circuit.
• Turn on ganged circuit breakers A4 and B4 and verify that the upper left and right LED’s are illuminated. If
the LED’s are not illuminated check the load attached to the circuits.
4. Perform the Learn function described in the Setup section.
- See page 15
5. Restore the Utility power by turning on the Utility Circuit Breaker which will toggle off the Generator Circuit Breaker.
6. Turn off the portable generator and disconnect from the MTS and store the generator per the manufacturers
instructions.
7. The system is now properly installed.
At the end of the Functional Test, train the home owner on the operation of the
MTS system and generator.
ELECTRICAL
All wiring must be the proper size and supported by appropriate conduit or raceways. All wiring and conduit
sizes and types should be in accordance with federal, state and local codes, standards and regulations.
