5.
Set the power switch to the ON position. Check the power and RUN / GREEN POWER LED
indicators on the front panel of the inverter source. If the LED is not lit, check your power source
and the connections to inverter. The other indicators should be off.
6.
Set power inverter switch to the OFF position. The indicator lights may blink and the internal alarm
may sound momentarily. This is normal. Plug the test load into the AC receptacle on the front
panel of the inverter. Leave the test load switch off.
7.
Set power inverter switch to the ON position and turn the test load on. The inverter should supply
power to the load. If you plan to measure the output voltage of the inverter, a meter such as
FLUKE 45, BECKMAN or other Digital Volt meter must be used.
K. Operation
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The power
inverter is now ready to deliver AC power to your loads. If you are operating several loads from
the power inverter, turn them on separately after the inverter has been turned on. This will ensure
that the power inverter does not have to deliver the starting currents for all the loads at once.
1. Controls and indicators
The ON/OFF switch turns the control circuit in the power inverter on and off. It does not disconnect
power from the power inverter.
The Inverter operates from an input voltage ranging from:
10 to 16 VDC for 12V models
20 to 32 VDC for 24V models
42 to 62 VDC for 48V models (By custom design only)
Peak performance for the inverter occurs when DC input voltage is in the Range of 10 volts to 16
volts for 12V models and 20 volts to 32 volts for 24V models, and 42 volts to 62 volts for 48V models,
from 150Watts up to 6000Watts.
2. Over voltage indicator
The over voltage indicator indicates that the power inverter has shut itself Down because its input
voltage higher than the detect voltage (12V / 24V / 48VDC versions).
3. Under voltage indicator
The under voltage indicator indicates that the power inverter has shut itself down because its input
voltage has been lower than detect voltage (12V / 24V / 48VDC versions).
4. Over temp indicator
The over temp indicator indicates that the power inverter has shut down because it has become
overheated. The power inverter may overheat because it has been operated at power levels above
its rating, or because it has been installed in a location which does not allow it to dissipate heat
properly. The power inverter will restart automatically once it has cooled off.
5. Overload indicator
The overload indicator indicates that the power inverter has shut itself down because its output
circuit has been short circuited or drastically overloaded. Switch the ON/OFF switch to OFF, correct
the fault condition, and then switch the ON/OFF switch back to ON.
L. Green Power Adjustment
Our inverter features automatic load-sensing, which allows the inverter to wait in Standby mode
until an AC load is switched ON. When an AC load appears the inverter will immediately start.
This feature conserves valuable battery energy as the inverter uses only about 10% of normal
power when in standby mode (standby is indicated by flashing green lamp). The amount of AC
power required to start the inverter can be adjusted, following the procedure below. Ensure
battery voltage is at nominal, i.e. 12V or 24V as appropriate for your inverter.
