E. Turn the inverter bypass breaker to the position noted in the residence wiring diagram on the
bypass box that will turn the inverter system on. The Power Module system is now fully connected
and operable. Should any problems arise that are not covered in this installation manual, contact
Trace Engineering or your dealer. Note: Perform the next step only if the inverter fails to Power up
when turned on.
F. Using a multi meter, check for appropriate battery voltage at the inverter DC terminals. (This will
require removing the end cover from the inverter.) If the battery voltage is appropriate confirm proper
battery cable polarity and connection, and make sure the batteries are not completely discharged. If
the inverter still doesn’t work contact your dealer or Trace Engineering.
Stacked Pair Inverters
If your P M includes a stacked pair of inverters the physical connection of the PM is no different. However,
since 240 volts AC is available across the two inverter’s AC outputs, connection of the AC loads to the
system via the bypass breaker is a little different. Refer to the section on stacking inverters in the individual
inverters owner’s manual included with the system.
Connect the AC loads that will run from 120 volts AC, to the AC output of the individual inverters at the
bypass breaker box. It is best to try and balance the AC loads between the two inverters if possible. The
load(s) that is to run from 240 volt AC output should be connected across the two inverters outputs by
connecting the neutral wire (white) to the neutral block in the bypass box, and one hot wire to each of the
inverter bypass box AC load points
