To start-up and test the stacked Trace Series:
1. Switch on the inverter designated as primary or INVERTER 1 (L1).
2. The inverter designated as secondary or INVERTER 2 (L2) will automatically
turn on.
The inverter should be providing 120 VAC/240 VAC to the sub-panel.
3. Use a true RMS voltmeter and measure the voltage between the L1 terminal
and the neutral bus in the sub-panel.
This voltage should be 120 VAC.
4. Use a true RMS voltmeter and measure the voltage between the L2 terminal
and the neutral bus in the sub-panel.
This voltage should be 120 VAC.
5. Use a true RMS voltmeter and measure the voltage between the L1 terminal
and the L2 terminal in the sub-panel.
This voltage should be 240 VAC.
6. Switch off one inverter (the other inverter will automatically switch off).
7. Replace all covers and panels on the inverters and sub-panel.
8. Switch on the inverter designated as primary or INVERTER 1 (L1).
9. The inverter designated as secondary or INVERTER 2 (L2) will automatically
turn on.
10. Switch on the breakers in the main panel feeding the inverters.
Ensure the inverters start to charge the batteries and power the sub-panel.
The stacked inverter system is now ready for use.

If the search mode is used on the Trace Series, the load that “awakens” the
inverters must be connected to the primary unit.

Until the unit is tested, no loads must be connected to the inverter’s
120 VAC or 240 VAC output.

The input source to the stacked pair should be 240 VAC with a neutral. If
only 120 VAC is supplied to one inverter (primary), the other inverter (secondary) will
enable its AC transfer relay. This will disconnect the AC output power to the loads
connected to the secondary inverter.

Remote controls can not be used with stacked inverters.
