Output Load
These five green LED's show the unit’s loading as a percentage of its maximum output.
The Overload LED is on if:
• The output exceeds the unit’s maximum rating.
• The output exceeds either of the transformer output winding ratings (Section 2.8).
WARNING: Do not run the unit when it is overloaded. Damage to the unit, the inverter
or the batteries can result.
If the unit is in Output Voltage Shutdown mode the LED’s will continuously sequence until
the condition is cleared (Section 4.5.2, “Sub Menu #50: Set Output Shutdown Param-
eters”).
