20-1000TUL INVERTER—OWNER'S MANUAL
Use the following instructions to operate the 20-1000TUL Inverter.
Step 1: Install the 20-1000TUL unit.
Completely install the inverter and charger using the instructions provided in
Section 2 of this manual.
Step 2: Apply an AC load.
Apply an AC load with AC input power present. The AC load is run directly
from AC input power. The ON-OFF/RESET Inverter Switch does not affect
the inverter's AC output when shore power is present.
Step 3: Turn on the inverter Remote Switch.
Step 4: Apply shore power to the 20-1000TUL/Ambulance shore line connection.
Push the ON-OFF/RESET Inverter Switch to the ON position. When
powered by the AC power, the ON lamp flashes, indicating that the inverter
is standing by.
Step 5: Verify Power.
Apply an AC load, such as a shop light or drill. The AC load is run directly
from AC input power.
Step 6: Observe the inverter operation.
Remove the shore line connection from the emergency vehicle. The unit will
automatically switch to Inverter mode and operate the AC load using battery
power. When shore power is restored, the unit examines the AC input for five
seconds and then switches the loads back to run directly from AC input
power.
With the ON-OFF/RESET Switch in the ON position, a double flash of the
ON light indicates the load demand is turned ON and the load is less than
5 Watts.
