PACKAGE CONTENTS Before installation, please refer to the following chart to ensure you have received the appropriate components for your model of Manual Transfer Switch.
OPERATION & INSTALLATION Utilizing a portable generator, your Manual Transfer Switch will power to selected circuits in the event that utility power is interrupted. The MMTS normal operation is to connect the Utility to the selected circuits using the internal Load Subpanel. The MMTS system can manually switch up to 8 AC circuits when operating on generator power.
OPERATION & INSTALLATION ! The installation of the MMTS shall conform to national and local electrical codes and should only be performed by a licensed electrician. Each installation of a manual transfer switch is unique and as such it is not possible for this manual to cover every configuration and procedure necessary to complete the installation; neither can potential hazards and/or the result of each method or procedure be anticipated in this manual. See Figure 2 for a typical install.
OPERATION & INSTALLATION FUNCTIONAL TESTING At the completion of the installation, test for proper operation; 1. Attach the portable generator to the MMTS 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.

SET UP The MMTS monitors power of the selected loads connected to the MMTS and displays the power output on each Phase using 8 LED’s for each Phase. After the MMTS is installed the breakers should be shut off before applying power to the MMTS. To test the unit turn on the Utility circuit breaker and turn on each load circuit breaker. Figure 4 show the MMTS circuit breakers set properly before turning on the generator.
SET UP Learn Function should be activated when on generator power to ensure that the generator can support the desired loads being controlled. The loads are should be turned on until desired generator capacity is reached. Additional loads, such as an electric heater, may be added during the Learn Mode process to force the generator to full capacity. To establish the capacity of the generator several methods may be used: 1.
SET UP NORMAL OPERATION As each circuit breaker is turned on the LED display should be examined to verify that the loads are balanced, within 2 LED’s illuminated on each side. The following figures show how the LEDs advance as the circuit breakers are turned on. Figure 6 – Only A2 “On A2 & B2 “On As each circuit breaker is turned on the LED display should be examined to verify that the loads are balanced, within 2 LED’s illuminated in each side.
TROUBLESHOOTING Problem Cause Correction No LED’s light on the control panel 1. All Circuit breakers are off 2. Utility is off and the Generator is not running or not connected 3. No load is on the circuits 1. Turn off the Circuit Breakers 2. Connect the Generator and turn on 3. Turn on loads on the circuits The LED’s are unbalanced 1.
