Inverter
WARNING: When the refrigerator is plugged in, 120 VAC is always
present at the inverter.
Note: Certain voltmeters will not be able to read voltage output from the
inverter. If there is no voltage or erratic voltage is measured, it does not
necessarily indicate a faulty inverter.
The inverter receives 120 VAC line-in from the power supply. The inverter
converts this single-phase, 60 Hz, 120 VAC into 3-phase, 230 VAC, with frequency
variations between 57 Hz and 104 Hz. This voltage is delivered to the compressor
through 3 lead wires. Each wire will carry identical voltage and frequency.
Note: The compressor leads must be connected to measure voltage output. If the
compressor wires are not connected, or if an open occurs in one of the 3 lead
wires or in the compressor, the inverter will stop voltage output.
When checking the inverter voltage output, connect the test-meter leads to any
2 of the 3 compressor lead wires at the inverter plug (plug should be connected).
The same reading should be measured between any 2 of the 3 wires.
