Inverter Operation
DANGER
DANGER OF SHOCK OR ELECTROCUTION - TREAT INVERTER
OUTPUT THE SAME AS COMMERCIAL AC POWER.
If servicing remove any frame covers required to gain
access to the inverter unit.
1. Turn ON the inverter at the ground control station
inverter ON/OFF switch. (Make certain the overload
LED is not lit on the inverter.)
2. Turn OFF the inverter. The overload LED may briefly
"blink" and the audible alarm may also sound a short
"chirp". This is normal.
3. When you have confirmed that the appliance (tool)
to be operated is turned off, plug the appliance cord
into the inverter AC output cord.
4. Turn ON the inverter.
5. Turn on the appliance (tool).
6. Plug in any additional appliances (tools).
NOTE: The audible alarm may make a momentary "chirp"
when the inverter is turned OFF. This same alarm
may also sound when the inverter is being con-
nected to or disconnected from the 24 volt battery
bank.
Inverter Troubleshooting
Inverter Specifications
Problem: No Input Voltage
Poor contact with battery termi-
nals. Shut down the inverter and dis-
connect battery power. Clean ter-
minals thoroughly and reconnect.
Blown DC battery fuse(s). Turn off inverter. Replace fuse(s)
with the same type and rating.
Problem: Inverter Is In Shut Down
Battery voltage is below 20 volts. Charge or replace battery.
Inverter is too hot (thermal shut
down mode). Overload LED indi-
cator on inverter is lit ORANGE/
RED. Allow inverter to cool. Check for
adequate ventilation. Reduce the
load on the inverter to rated con-
tinuous power.
Unit may be defective. See warranty and call customer
service.
Problem: Low Battery Alarm On All The Time
Input voltage below 21 volts -
buzzing sound. Keep input voltage above 21 volts
to maintain regulation.
Poor or week battery condition. Recharge or replace battery(s).
Inadequate power being delivered
to the inverter or excessive volt-
age drop. Use lower gauge (heavier) cable.
Keep cable length as short as pos-
sible.
