2-7-8 Over voltage protection indicator: (OVP)
The over voltage indicator indicates that the power inverter has shut itself down
because its input voltage exceeded 12V/24V/48VDC version. (See page 12)
2-7-9 Under voltage protection indicator: (UVP)
The under voltage indicator indicates that the power inverter has shut itself
down because its input voltage fell below 12V/24V/48VDC. (See page 12)
2-7-10 Over temp protection indicator: (OTP)
The over temp indicator indicates that the power inverter has shut itself down
because its temp has become overheated. The power inverter may overheat
because it has been operated at power levels above its rating, or because it
has been installed in a location which does not allow it to dissipate heat
properly. The power inverter will automatically back up, once it has cooled off.
2-7-11 Overload protection indicator: (OLP)
The overload indicator indicates that the power inverter has shut itself down.
When output voltage over continue power, then must return to operate manually.
