4.9 INVERTER
The inverter converts 48 VDC to 110 VAC to allow operation of
power tools from the machine’s batteries.
• The inverter is operational when the emergency stop switch is
pulled out.
• The machine and inverter can be operated at the same time.
• The inverter will shut off at approximately 42 VDC and stay off
until the emergency stop switch is recycled. It will operate
again until voltage drops to 42 VDC.
• The machine will operate down to 36 VDC.
• The inverter will shut down if the high temperature light indi-
cated overheating. It will automatically turn back on when
cooled.
• The overload light indicates an output wiring short circuit or a
load that is too large for the rating of the inverter.
