2. Second-level access - First, ensure no
power source of any kind is connected
to the inverter. If power has been
connected, wait 10 minutes after power-
down and verify the Charge Lamp
indicator is OFF to proceed. Then locate
the two screws at the bottom corners of
the main front panel. Use a Phillips
screwdriver to loosen the screws and tilt
the cover outward for removal. (The
screws are retained in the cover.)
Notice the large power terminals at the bottom of the wiring area. The rubber grommets
below the power terminals are for wire entry/exit to the power source and motor. Never
operate the inverter with the front panel removed.
The control terminals connect logic or analog signals for control and monitoring of the
inverter. The nearby alarm relay provides both normally-open and normally-closed logic for
interface to an external alarm. The alarm circuit may carry hazardous live voltages even
when the main power to the inverter is OFF. So, never directly touch any terminal or circuit
component.
