power checks that follow.
If a minus sign (–) appears in the meter display, the polarity of the 48VDC power to the
cage is reversed. Verify the meter settings and connections. If the meter is properly set
and connected, carefully examine the wiring between the external 48VDC power supply
and/or batteries, determine the location of the polarity reversal, and correct the wiring
error before continuing.
Do not insert or remove the power supply unit from the cage when turned ON.
Sudden power surges could damage system components.
